Definitions
- Excellent unaided distance vision is also known as emmetropia.
- the inability to focus on distant focal points is known as myopia and the inability to focus on near focal points is known as hyperopia.
- “distance” vision is considered any focal point 1 meter or more from the eye and near vision is any focal point less than 1 meter from the eye.
- the minimum focal length at which an object will come into focus is known as the“near point”.
- Accommodation The change in focus from distance to the near point and any focal point in between is called accommodation.
- Presbyopia occurs because as a person ages the eye’s accommodative ability which uses near reflex-pupil constriction, convergence of the eyes and particularly ciliary muscle contraction, decreases. This reduction in accommodation results in an inadequate change in the normal thickening and increased curvature of the anterior surface of the lens that is necessary for the shift in focus from distant objects to near objects.
- Important near focus tasks affected by presbyopia include viewing computer screens (21 inches) and reading print (16 inches).
- Presbyopia is a normal and inevitable effect of ageing and is the first unmistakable sign for many in their forties that they are getting older.
- Presbyopia carries with it a stigma resulting from the limitation in ability to quickly function at many tasks requiring focusing at both distant and near points, which once occurred almost immediately.
- these tasks can be performed only by the use of eyeglasses, contact lenses or after undergoing invasive surgery.
- One such optical modification, the monovision procedure can be executed with the use of glasses, contact lenses or even surgery.
- the monovision procedure corrects one eye for near focus and the other eye for distance focus.
- monovision correction is normally accompanied by loss of depth perception and distance vision particularly in dim light (e.g. night).
- AcuFocus work by inlaying a pinhole on the cornea to increase the depth of focus.
- a similar effect can be achieved with general miotic agents, such as pilocarpine (a non- selective muscarinic acetylcholine receptor agonist), carbachol (a non-selective muscarinic acetylcholine receptor agonist), and phospholine iodide (an acetylcholinesterase inhibitor).
- general miotic agents such as pilocarpine (a non- selective muscarinic acetylcholine receptor agonist), carbachol (a non-selective muscarinic acetylcholine receptor agonist), and phospholine iodide (an acetylcholinesterase inhibitor).
- Miotic agents have been described in various patent and patent applications for the treatment of presbyopia.
- US Patent Nos. 6,291,466 and 6,410,544 describe the use of pilocarpine to regulate the contraction of ciliary muscles to restore the eye to its resting state and potentially restore its accommodative abilities.
- WO/2013/041967 describes the use of pilocarpine with oxymetazoline or meloxicam to temporarily overcome ocular conditions such as presbyopia.
- US Patent No. 8,299,079 (HEK Development LLC) describes the use of direct acting general miotic agents such as pilocarpine, carbachol and phospholine iodide with the alpha 2 selective vasoconstrictor brimonidine at a concentration from 0.05% to 3.0% w/v.
- brimonidine concentrations of about 0.20% (or any at or above 0.05%) w/v induces ciliary spasm with often migraine intensity brow and/or head aches, and frequently results in increased rebound hyperemia.
- rebound redness occurs in 25% of patients using brimonidine 0.20% w/v (Alphagan ® , registered trademark of Allergan, Inc.) twice daily.
- US Patent Application Publication No. 2014/0113946 describes the use of pilocarpine with the alpha 1 and mild alpha 2 agonist vasoconstrictor oxymetazoline, demonstrating limitations in distance sharpness and duration, whereby a cohort largely restricted to mild hyperopes is required to neutralize the induced myopia (Table 1). Of the 16 eyes treated only three were -0.25 to -0.50 diopters, and eight were mildly hyperopic. Of the -0.50 diopter eyes two were reduced to 20.40 distance. Further, duration was limited as full effect became diminished in about four hours. Pupil size range was from 2.0 mm to 2.7 mm, where enhanced near effect and distance sharpness from depth of focus was minimal to absent.
- aceclidine is unstable in solution. Normally, aceclidine is stored in a two-bottle system; one bottle containing the lyophilized aceclidine and the second bottle containing the diluent necessary to reconstitute the lyophilized aceclidine before topical instillation.
- the primary issue with its use as a presbyopic miotic is the attendant pain and in some cases distance blur that may be induced.

- a two-bottle system one bottle containing the lyophilized aceclidine and the second bottle containing the diluent necessary to reconstitute the lyophilized aceclidine before topical instillation.
- compositions and methods of the present invention treat presbyopia by improving depth of focus in patients with presbyopia by administering an ophthalmological composition to the eye that reduces pupil dilation in the dark or in dim light, produces a particular degree and duration of miosis without accommodation, provides cosmetic whitening and/or induce redness prophylaxis.
- the compositions and methods of the present invention also do not cause significant pupil rebound, tachyphylaxis, ciliary spasms, induction of myopia or reduction in distance vision. Additionally, the compositions and methods of the present invention allow for the further improvement in visual acuity and depth perception of binocular (both eyes) treatment.
- the ophthalmological composition of the present invention surprisingly creates a pupil of from about 1.5 to about 2.4 mm at the anterior iris plane and about 2.0 mm at the comeal surface.
- the clinical effect appears to involve both with modulated increase in accommodative tone and enhanced pinhole near depth of focus for improved near vision, estimated to be about -1.25 D or less, but restricted in power to remain wihin the range of pinhole correction for distance, found to be about -1.00 D or less creating a sum increase that may in some cases create a near vision add of +2.00 D or more without distance blur; and with a reduction or ablation of the redness that is otherwise a hallmark of the use of miotic agents.
- accommodative tone is superior to the pinhole effect of the Kamra ® and Flexivue Microlens ® comeal inlays, allowing binocular treatment without peak dimming.
- Pupil miosis of the present invention with modulated accommodation is also superior to inlays because the constriction of the actual pupil does not result in the attendant severe night vision disturbance caused by the light scattering borders of the pre-comeal pinholes created by the inlays.
- Further pupil miosis provides a greater field of vision and transmission of more focused light, and in a discovered optimal pupil range of about 1.5 mm to 2.1 mm using formulation discoveries of the present invention does so with negligible to mild and very tolerable dimming and enhanced contrast, distance vision, reduced glare at night, and improved near vision.
- aceclidine has a minimal effect on the longitudinal ciliary muscle, thus reducing risk of retinal detachment when compared to the use of general muscarinic agonists such as pilocarpine and carbachol.
- a cycloplegic agent resulted in only 0.04 mm of anterior chamber shallowing.
- Aceclidine, particularly as enhanced for the present invention also has greater magnitude, duration, and control of minimum pupil diameter than conventional pilocarpine with or without alpha agonists, and less anterior chamber inflammation with chronic use.
- compositions of the present invention achieve these advantages by allowing both pinhole near vision depth perception benefit and modest accommodative increase below the threshold of induced myopic distance blur through the miotic pupil, whereby, not wishing to be held to particular theory, it is believed the rate of miosis and the rate of accommodative increase maintain a synchronous balance in preferred embodiments allowing pinhole correction of otherwise induced accommodative blur in prior art applications of miotics for presbyopic correction.
- pilocarpine must be instilled monocularly to minimize intolerable distance blur to a still bothersome 2-3 lines of distance blur. Even instilled monocularly, pilocarpine still may create bothersome attendant distance blur and must be restricted to about 1.0%.
- pilocarpine pupil size is about 2.3 mm or larger in most subjects and thereby restricts any significant pinhole depth perception benefit as well as any pinhole filtering of induced myopic rays.
- the restriction to about 1.0% for these conventional formulations of pilocarpine with the attendant short duration and still bothersome but reduced distance blur in emmetropes or myopes (somewhat neutralized in low hyperopes) are attempts to prevent extremely strong
- any effects on accommodation may be further reduced or totally eliminated in preferred embodiments by combining a miotic with a cycloplegic agent in a narrow and particular ratio of miotic to cycloplegic, where such ratios as discovered for US 9, 089,562, such as about 35:1 for a preferred embodiment, become greatly increased for the present invention in the presence of cryoprotectant as to a factor of about 300% - 700%.
- Aceclidine is capable of producing the increased depth of focus by both pupil miosis below 2.3 mm and modest accommodation described in the present invention. Particularly enhanced miosis occurs with use of compositions of the present invention.
- aceclidine may produce either less than optimal pupil miosis at low concentrations or at higher concentrations require more than desired peak miosis to attain satisfactory duration of greater than 3-4 hours.
- a cycloplegic agent has been found to be highly sensitive to other inactive ingredients in the formulation not usually associated with effects on active agents, and particularly for cryoprotectants as found to be preferred commercially for aceclidine reduce or eliminate the need for this cycloplegic requirement to extremely low concentrations in a preferred embodiment, rendering 0.042% sufficiently high when a cryoprotectant is present (e.g.
- aceclidine without formulation enhancements of the present invention causes dimming of vision in dim or absent lighting as well as ciliary pain above a reasonably tolerable threshold that may last for an hour or more and be similar to a severe migraine headache.
- Certain embodiments of the present invention enhance the discovered preferred degree of pupillary miosis by providing a consistent range of effect of about 1.50 - 2.20 mm for most patients using a preferred embodiment of a nonionic surfactant and viscosity enhancer. Similar benefit may be achieved using other permeation enhancers, particularly hydroxypropylmethyl cellulose, high viscosity carboxymethyl cellulose, Carbopol ® (polyacrylic acid or carbomer), and various viscosity additives that increase drug residence time, such as xanthan gums, guar gum, alginate, and other in situ gels well known to experts in the art.
- the present invention further prevents nasal congestion otherwise occurring when substantial aceclidine levels reach the nasal mucosa, due to the rheologic properties of the preferred embodiment.
- a selective a-2 adrenergic receptor agonist such as fadolmidine, brimonidine or guanfacine
- a selective a-2 adrenergic receptor agonist such as fadolmidine, brimonidine or guanfacine
- brimonidine 0.20% w/v when topically applied for pupil modulation for night vision, result in tachyphylaxis of pupil modulation due to a-2 receptor upregulation in almost 100% of treated subjects within four weeks of use.
- the addition of a cycloplegic agent results in reduction of any brow ache or associated discomfort by further reducing the degree of ciliary spasms on topical instillation without impairing the miotic response.
- the ratio of 1.40% aceclidine to about 0.040% tropicamide in a preferred embodiment of U.S. Patent No. 9,089,562 (35:1) becomes about 1.75% aceclidine to about 0.004% to 0.010% tropicamide (350:1, 175:1 respectively) in the presence of mannitol, where 2.5% provides better effect than 4.0%.
- cycloplegic agents cause pupil mydriasis (i.e. dilation of the radial muscle of the iris). Further, the addition of a cycloplegic agent to the miotic agent unexpectedly increases the time at which the pupil maintains the desired size range without becoming too restricted. Peak miotic effect at 30 - 60 minutes can be titrated in inverse relation to the cycloplegic
- concentrations of tropicamide discovered in the present invention apparently cause more relaxation of the ciliary muscle than the iris radial musculature.
- iris mydriasis is discovered to be suppressed by the addition of tropicamide to compositions containing concentrations of aceclidine used in the present invention, with instead a more consistent level of miosis for the duration of the miotic effect.
- the addition of tropicamide can reduce the degree of peak pupil miosis without inducing mydriasis thereby creating a more constant and ideal pupil size throughout the drug induced miosis.
- This more consistent pupil size allows for beneficial near and distance vision without the adverse dimming or loss of resolution due to diffraction limits at the very reduced pupil sizes seen at peak pupil miosis (e.g. 1.25 mm).
- aceclidine (1.40%) to the eye, in a preferred embodiment, but such
- formulations are not as constituted sufficiently stable for commercial use, and typically have a duration of about five to six hours maximum.
- cryoprotectant can therefore also be used to greatly reduce (i.e. no more than 0.025% w/v cycloplegic agent, preferably 0.004% to 0.015% and most preferably 0.005% to 0.010%) the concentration of cycloplegic required to further eliminate mild, but potentially bothersome, ciliary side effects particularly in younger presbyopes and further modulate pupil miosis over aceclidine and a cryoprotectant combinations alone, reducing and in most cases eliminating any bothersome peak concentration dimming, as found in preferred embodiments of the present invention.
- aceclidine about 1.50% - 2.0% and more preferably 1.75% and mannitol about 0.5% - 4.0% and more preferably 2.5% provide optimal concentration combinations for the present invention, that are necessary but not sufficient for about 3 lines of near improvement and 5 or more hours duration desired for an effective topical presbyopic composition, where additional formulation discoveries can further enhance the desired clinical near improvement magnitude and duration;
- Viscosity agents such as high viscosity carboxymethyl cellulose (“CMC”) are surprisingly discovered to moderately enhance magnitude and greatly enhance duration, unlike with formulations in a. above alone.
- High molecular weight CMC concentrations of 0.75% to 1.75%, and most preferably about 1.40%, or hydroxypropylmethyl cellulose (“HPMC”) at about 0.25% to 2.0%, more preferably about 0.50% or 1.50%, and most preferably about 1.0% to 1.25%, when combined result now in about +3 lines of near vision improvement or greater, at a duration of 5 - 10 hours, at a mean of about 7 hours or greater vs. pilocarpine 1.0% of about less than 4 hours;
- citrate in combination with EDTA as a preferred embodiment buffer appears to 1) reduce redness; 2) enhance sorbate preservative shelf life, and in combination of the above with BAK 0.005% to 0.02% (0.02% preferred) further enhances near vision lines to about 4 lines and duration to about 8 to 12 hours.
- sodium chloride may be substituted with boric acid, preferably at 0.35% or potassium borate, preferably at 0.47%;
- nonionic surfactant at optimized concentration of about 2.5% to 5.0% enhances permeation of aceclidine into the eye, which may relate to optimal micellar size particularly once of micromicallar or nanomicellar range. This increased permeation coincides with the desirable increase in magnitude and duration and absent tropicamide but in the presence of mannitol with slight increases in ciliary sensation and dimming. Therefore in the presence of the combined formulation enhancements of a-d. above, where a cycloplegic agent is no longer required for a-d.
- addition of a nonionic surfactant at concentrations found to be preferred may be further improved with much lower concentrations of a cycloplegic agent than those found in US 9.089,562, such as the use of about 0.042% tropicamide with aceclidine 1.40%.
- a nonionic surfactant at concentrations found to be preferred may be further improved with much lower concentrations of a cycloplegic agent than those found in US 9.089,562, such as the use of about 0.042% tropicamide with aceclidine 1.40%.
- embodiments include aceclidine of about 1.75%, mannitol 2.5%, polysorbate 80 of about 2.5% to 5.0%, CMC of about 1.42%, or HPMC of about 1.8% and tropicamide of about 0.004% - 0.010%, more preferably about 0.005% to 0.007%, and most preferably about 0.005% - 0.006%.
- Micelle formation above the critical micellar concentration may allow for micelles to spread across the tear film surface and spread at low concentrations to cover this surface, while at higher concentrations these micelles becoming increasingly contracted and“squeezed” along the surface.
- a minimal micelle diameter is achieved before significant multiple lamellae (layering) occurs.
- nanomicelles of about 100 to 250 ran along the surface are achieved surrounding the highly charged and hydrophilic aceclidine, facilitating its penetration through the very lipophilic epithelium;
- BAK 0.02% to sorbate about 0.10%, EDTA about 0.10%, in a preferred composition of aceclidine 1.75%, mannitol 2.5%, tropicamide 0.01%, and citrate buffer (1 to 100 mM 3-5 mM preferred) is above the BAK critical micellar concentration.
- BAK being a cationic surfactant
- the concentration of such nonionic nucleophiles at a preferred pH in the preferred embodiment is relatively low, but the ability of these nonionic nucleophiles to destabilize adjacent aceclidines repeatedly without themselves degrading is otherwise high.
- the result may be improved potency for 1 month plus of a mixed solution once opened in a dual chamber bottle and mixing occurs of lyophilized aceclidine/mannitol with the remainder of the formulation in the diluent and or improved stability sufficient for commercialization in solution, either at room temperature or via cold chain; [066] It is discovered that BAK alone does not provide sufficient bacterial and fungal preservative efficacy but that BAK and sorbate, or sorbate alone satisfactorily preserve diluent and or mixed solutions of the invention;
- preferred embodiments of the present invention such as containing 1.25% hydroxypropyl methyl cellulose may have a viscosity of about 400 cps prior to instillation, yet unlike conventional high viscosity artificial tear formulations such as Celluvisc® at about 400 cps, which may blur vision for 10-20 minutes or Liquigel® at about 100 cps, which causes similar but slightly reduced blurring causes only about 60 seconds of blur dissipating rapidly with an influx of tear secretion; where both a
- nonnewtonian reduction in viscosity at high shear (such as about 1/1000 sec during a blink, and aceclidine parasympathetic trigger of tear secretion as a sialogen may contribute.
- General miotic agents such as pilocarpine, carbachol and phospholine diesterase, are capable of causing pupil miosis resulting in improved near vision of presbyopic patients.
- Comfort, safety, and efficacy of a preferred embodiment of an ophthalmological composition of the present invention results from the presence of a nonionic surfactant, such as cyclodextrin alpha, beta, or gamma chains, preferably 2-hydroxypropyl beta-cyclodextrin (‘ ⁇ RbOO”), and, sulfobutyl ether derivative of b-cyclodextrin (Captisol ® ), a polyoxyl alkyl such as polyoxyl 40 stearate and polyoxyl 35 castor oil, or a poloxamer such as poloxamer 108 and poloxamer 407, a polysorbate such as polysorbate 80 or Brij® 35(Brij is a registered trademark of Uniqema Americas LLC); a viscosity enhancing agent, such as carboxymethyl cellulose (“CMC”); a tonicity adjustor, such as sodium chloride; a preservative, such as benzalkonium chloride and
- compositions of the present invention comprising a viscosity enhancer may be from about 1 to about 10,000 cps prior to topical instillation in the eye.

- Advantages of such a device for embedding an active agent or agents as drug into a daily disposable contact lens include one or more of:
- Such an invention minimizes risk of contact lens material change as well as providing a means for ensuring stability of the formulation to be embedded.
- more conventional active agent miotics such as pilocarpine or carbachol may similarly be embedded within a contact lens using a similar device at the time of wear to minimize material exposure to these agents until the time of wear such that one chamber contains the active agent in higher concentration than desired dissolved in desired and typically proprietary blister pack vehicle, and another a blisterpack conventional vehicle such that the combination when mixed achieves the desired percentage of active agent.
- This also allows for a subject to wear contact lenses embedded with active agent miotics with minimal risk of modification to contact lens material and stability retained during shelf life until embedding in to contact lens occurs at the time of wear.
- a longer duration of delivery per day of the same concentration found safe and efficacious may allow for greater total drug delivery per day and a compressed time frame to achieve efficacy improving from the current weeks to month to significantly fewer days to weeks.
- any topical solution containing an active agent or agents designed to provide topical delivery for presbyopic correction whether transient or permanent to said eye of a subject by delivery to a contact lens at the time of blister pack sterilization.
- the agent or agents are determined to be safe to the contact lens material, and maintain stability for an acceptable commercial shelf life.
- This addition at time of instillation would allow at the time of wear of said daily wear disposable contact lens prolonged delivery over a greater time frame during the wearing cycle - including particularly even the first 30 minutes of wear.
- the advantage of this delivery in all cases of topical presbyopic drugs results in prolonged wearing times and or potential for compressed time frames to achieving onset of efficacy in presbyopic improvement for said subject.
- the ability to immerse said daily wear disposable contact lenses with desired active agents of any drug at the time of wear improves not only the integrity of the contact lens material over its commercial shelf life of typically several years, but also the stability of the active agent being in a separate chamber until embedded within said contact lens on the day of wear when opened and the chambers mix.

- the selective a-2 agonist may be included within the composition of the present invention or applied topically preferably just minutes before or less preferably just minutes afterward if additional means to reduce nasal congestion or redness is desired for sensitive subjects.
- Selective a-2 agonists suitable for the present invention have minimal a-1 agonist activity at low concentrations. For example, for brimonidine or fadolmidine, 1% to 2% w/v is considered extremely high, 0.5% to 1.0% w/v still highly inductive of a-1 receptors and toxic for purposes of the present invention. Further, 0.10% to 0.5% w/v is still too high and even 0.070% to 0.10% w/v is associated with a higher than preferred incidence of rebound hyperemia
- brimonidine, fadolmidine and guanfacine preferentially stimulate a-2 adrenergic receptors, and even more preferably a-2b adrenergic receptors so that a-1 adrenergic receptors are not stimulated sufficiently enough to cause excessive large vessel arteriolar constriction and vasoconstrictive ischemia.

- cyclodextrins and/or polyoxyl 40 stearate as a nonionic surfactant component or as the sole nonionic surfactant, result in a greater whitening effect when the a-2 agonist is included in the composition rather than poloxamer 407.
- the a-2 agonist may optionally be applied separately or in certain preferred embodiments with formulations of the present invention that do not include an a-2 agonist, such as those formulas with polyoxyl 40 stearate 5.5% w/v as the non-ionic surfactant, although the a-2 agonist is not required except for occasional sensitive subjects. Fadolmidine represents the a-2 agonist with highest hydrophilicity and therefore high surface retention for the present invention.
- Guanfacine is also highly selective and hydrophilic.
- Brimonidine is highly selective with moderate lipophilicity.
- dexmedetomidine has high selectivity with high lipophilicity that may be used with less efficacy for reducing redness for the purposes of the present invention (although possibly inducing fatigue as a side effect in some patients).
- borate buffer 5 mM and BAK 0.007% w/v results in redness of about 1.0 to 1.5 out of 4 which is transient lasting about ten minutes, and by 30 minutes returns to about baseline.
- the selective a-2 adrenergic receptor agonist is a compound which has binding affinity of about 900 fold or greater, even more preferably about 1000 fold or greater, and most preferably, about 1500 fold or greater.

Analogues of these compounds that function as highly selective a-2 agonists may also be used in compositions and methods of the present invention.
- the selective a-2 agonist is selected from the group consisting of fadolmidine, guanfacine and brimonidine.
- the selective a-2 agonist is brimonidine in the form of a salt at a concentration of 0.025% to 0.065% w/v, more preferably from 0.03% to 0.035% w/v.

- HCl hydrochloride
- the selective a-2 agonist is guanfacine at a concentration from about 0.005% to about 0.05% w/v, more preferably from 0.02% to about 0.035% w/v in the form of an HCl salt.
- the selective a-2 agonist is dexmedetomidine at a concentration from about 0.005% to about 0.05% w/v, more preferably from 0.04% to about 0.05% w/v in the form of an HCl salt.
- a pH less than physiologic pH is found to enhance the whitening effect for brimonidine, preferably pH 4.5 to 6.5, and more preferably pH 5.5 to 6.0.
- redness reduction is achieved at all pHs, and enhancement of aceclidine absolution occurs at alkaline pH, such that more effect occurs from a given concentration, and therefore while effective at pH ranges from 4.5 to 8.0, pH range of 6.5 to 7.5 is preferred for the present invention, and 7.0 to 7.5 most preferred.
- the present invention is further directed to an ophthalmological composition further comprising a cycloplegic agent.
- a cycloplegic agent can be combined with miotic agents, particularly for the present invention, aceclidine, without reducing miotic onset, magnitude, or duration; and further blunt the normally attendant spike in miotic effect coinciding with time of peak absorption in aqueous formulations to provide a constant miosis versus time after onset from 15 to 30 minutes to 6 to 10 hours depending on the desired formulation.
- the addition of the cycloplegic agent also reduces any residual associated discomfort that may otherwise occur soon after topical instillation, which presumably is a result of ciliary spasms or excessive pupillary miosis.
- Cycloplegic agents suitable for the present invention include, but are not limited to, atropine, Cyclogyl ® (cyclopentolate hydrochloride), hyoscine, pirenzepine, tropicamide, atropine, 4-diphenylacetoxy-N-methylpiperidine methobromide (4-DAMP), AF-DX 384, methoctramine, tripitramine, darifenacin, solifenacin (V esicare), tolterodine, oxybutynin, ipratropium, oxitropium, tiotropium (Spriva), and otenzepad (a.k.a.
- the cycloplegic agent is tropicamide at a concentration from about 0.004% to about 0. 025% w/v, more preferably from about 0.005% to about 0.015% w/v and still more preferably from about 0.005% to about 0.011% w/v, from about 0.005% to about 0.007% w/v and from about 0.005% to about 0.006% w/v.
- the cycloplegic agent is a mixture of tropicamide at a concentration from about 0.04% to about 0.07% w/v or pirenzepine or otenzepad at a concentration from about 0.002% to about 0.05% w/v.
- tropicamide 0.01% w/v was found to slightly reduce brow ache, 0.030% w/v to further reduce brow ache and from 0.04% to about 0.07% w/v to completely eliminate brow ache without reduction of the average pupillary miosis diameter over duration of effect.
- Tropicamide in preferred embodiments has demonstrated completely unexpected sensitivity of effect, where at about 0.04% w/v unexpectedly and very effectively reduces or eliminates brow ache and ciliary spasm pain, becoming very noticeably further reduced at 0.042% w/v and absent at 0.044% w/v in a preferred embodiment with no cycloplegia (surprising due to its common use as a pupil dilating agent).
- tropicamide did not reduce the mean degree of pupil miosis, the time of onset of pupil miosis or the subsequent visual benefits.
- tropicamide blunted the peak miosis seen in aqueous formulations to create a smooth consistent miotic effect over time. It allowed modulation of peak pupil miosis to achieve a more even effect over time with no dilation as has been found with its prior use.
- tropicamide is useful to prevent transient constriction below 1.50 mm at 30 to 60 minutes following aceclidine in some embodiments and to reduce transient excessive and undesirable dimming of vision that may otherwise occur at peak onset of about 30 minutes.
- an ophthalmological composition comprising 1.53% w/v aceclidine, 5% w/v HPpCD, 0.75% w/v CMC, 0.25% w/v NaCl , 0.01% w/v BAK and a phosphate buffer at pH 7.0; or 1.45% w/v aceclidine; 5.5% w/v polyoxyl 40 stearate; 0.80% w/v CMC; 0.037% w/v NaCl; 0.015% w/v EDTA; 0.007% w/v BAK and 5mM phosphate buffer at a pH 7.0; was varied from 0.040% w/v tropicamide, where moderate dimming was noted, to 0.044% w/v tropicamide where dimming became almost undetectable other than in extremely dim light conditions.
- tropicamide achieves this blunting effect without causing mydriasis. Further, in a preferred embodiment, tropicamide 0.014% w/v was found to reduce brow ache, 0.021% w/v to further reduce brow ache and from 0.028% to 0.060% w/v and in some embodiments up to 0.09% w/v to completely eliminate brow ache without cycloplegia (i.e. paralysis of ciliary muscle of the eye).
- FIG. 1 shows the effect of a miotic agent with or without a cycloplegic agent and with or without a carrier.
- Subject is an emmetrope over the age of 45 with a baseline near vision of 20.100 and baseline distance vision of 20.20.
- Topical administration to the eye of 1 % w/v pilocarpine in saline solution results in an improvement of near vision to 20.40 (8a), however this improvement comes at the expense of a reduction in distance vision to 20.100 (8b).
- the carrier increases the beneficial effect of aceclidine resulting in better than 20.20 near vision.
- lOe and lOf show the effects of adding 0.042% w/v tropicamide to the aceclidine in the carrier.
- FIG. 1 shows that aceclidine is capable of temporarily correcting near vision in a presbyopic subject without affecting the baseline distance vision. Similar results can be achieved with a different miotic agent, pilocarpine, with the addition of a cycloplegic agent such as tropicamide. A proper drug carrier can also have a beneficial effect.

- Example 1 Effect of aceclidine on vision of subjects aged 47 to 67 years
- Table 1 demonstrates the effect on the near focus ability of presbyopic subjects before and after ophthalmological administration of a composition containing aceclidine.
- Each composition included aceclidine in the concentrations indicated and 5.5% w/v HPpCD, 0.75% w/v CMC, 0.25% w/v NaCl and 0.01% w/v BAK.
- compositions administered to subjects 4 and 5 included 0.125% w/v tropicamide.
- aceclidine is an enantiomer
- the clinical effectiveness may vary with different ratios. For the present studies a nearly exact 50:50 ratio of stereoisomers was measured as best determined by polarimetry.
- Table 2 Effect of concentration of concentration of acedidine and tropicamide.
- (C) indicates corrected vision
- (m) indicates minutes
- (hr) indicates hour
- mm indicates millimeters
- BD indicates baseline distance vision
- BN indicates baseline near vision
- BP indicates baseline pupil size
- OD indicates right eye
- OS indicates left eye and OU indicates both eyes.
- Time refers to duration of the effect.
- aceclidine at a concentration of at least 1.1% w/v was able to reduce the size of the pupil to 1.63 mm 1 hour after topical instillation resulting in corrected near and distance vision for at least 10 hours.
- Lowering of the concentration of aceclidine to 0.75% w/v (formula #3) reduced the miotic effect to 2.0-2.5 mm after 1 hour and vision correction lasted only 6.5 hours.
- the addition of 0.03% w/v brimonidine reduced redness of the eye (4 out of 4 without brimonidine, not shown) to 1.5 out of 4 within 30 minutes after topical instillation which was maintained for the entire time vision was corrected.
- formula #7 To determine the effect of brimonidine on pupil miosis, formula #7, was administered. Administration of formula #7 resulted in only a slight decrease in pupil miosis to 1.70 mm with identical distance and near vision improvement to that of formula #5. A 2-3+ conjunctival injection was noted.
- Example 3 Effect of concentration of aceclidine, brimonidine, guanfacine, fadolmidine, tropicamide and additives Table 3: Effect of concentration of aceclidine, brimonidine, guanfacine, fadolmidine, tropicamide and additives.
- Baseline vision was 20.20 both eyes for distance; 20.70 right eye unaided for near; 20.80 left eye for near (best @ 16”).
- D/C stands for discontinued after eye washing due to intolerable stinging.
- Aceclidine at a concentration of 1.55% w/v was able to reduce the size of the pupil to about 1.63 mm 30 minutes after topical instillation resulting in corrected near and distance vision to 20.20 or better for at least 6 hours, with noticeable affect lasting about 7.5 hours as seen in Table 3.
- Lowering of the concentration of aceclidine to 1.25% w/v resulted in useful near vision improvement to about 20.25 - 20.30, but not as effective as at the higher dose range alkaline pH resulted in quicker onset, longer duration, and greater effect.
- AB11T did not include glycerin, poloxamer 188, or polyoxyl 40 stearate, which resulted in substantial stinging and discontinuation of the experiment with eye flush irrigation immediately after topical instillation.
- Substitution of guanfacine 0.037% w/v in AB12T for brimonidine resulted in minimal initial redness with prolonged redness reduction and some degree of whitening, and appeared to provide overall the best cosmesis though requiring slightly higher aceclidine concentration for optimal effect.
- AB4T and AB6T were repeated both monocularly and binocularly. Substantial improvement in depth perception, near point acuity to 3 pt (20.15), and near point distance (8”, 20.20) was noted when both eyes were treated vs. monocular treatment. Monocular treatment resulted in worsening of vision with both eyes open versus testing only the treated eye.
- Example 4 Effect of concentration of aceclidine, brimonidine, tropicamide, and additives Table 4: Effect of concentration of aceclidine, brimonidine, tropicamide, and additives.
- a decrease in the amount of aceclidine from 1.61% to 1.53% w/v resulted in a pupil size range from 1.8-2.0 mm. Dimming as a result of the restriction of the pupil decreased linearly from 1.5 to 0.5 with the decreased amount of aceclidine.
- the 1.8 to 2.0 mm pupil created 41% more light than the 1.5 to 1.7 mm pupil.
- the 1.8 to 2.0 mm pupil had a near depth increase of 1.75 D. This is only a 0.25 D loss from the beneficial 2.00 D seen with the 1.5-1.7 mm range.
- the 1.80 to 2.0 mm range produces 41% more light while still allowing the full benefit of increased near vision in individuals under 60 years of age; whereas, individuals 60 years of age and over still experience total computer benefit and some increased near benefit.
- Table 4 shows an unexpected result seen in formulas #13 and #17 where the increase ofNaCl from 0.25% w/v to a range of 0.50 to 0.75% w/v resulted in an acceptable redness score of only 1.0 even without the addition of the redness reducing agent brimonidine.
- Formulas #15, #16 and #17 each result in an overall maximum rating of 5 by combining the benefits of: (1) reduced aceciidine concentrations to improve the amount of light produced without significantly affecting the near vision benefits seen in formulas #8 - #12; (2) increased NaCl concentrations resulting in a further reduction in redness even in the absence of brimonidine; and (3) increased CMC concentrations resulting in longer residency time on the eye.
- Formula #19 is an excellent alternative for the minority of individuals that are high responders to formulas #15- #17 and get noticeable dimming with 1.53% w/v aceciidine.
- Formula #20 is an excellent alternative for the minority of individuals that are low responders to formula #19.
- Formula #21 is an excellent alternative for the minority of individuals that are low responders and get poor pupil response with Formula #20.
- a viscosity enhancer preferably CMC 0.80% w/v or an amount of Carbopol ® 934 or 940 sufficient to achieve a viscosity of from about 5 to about 35 cps upon topical instillation, such as Carbopol® 940 at a concentration from about 0.09% to about 1.0% w/v;
- a phosphate, citrate, citrophosphate, or acetate buffer from about 3 to about 10 mM
- pH is from about 4.75 to about 6.0.
- Example 7 Use of a preferred embodiment to prolong contact lens wear.
- a viscosity enhancer preferably CMC 0.80% w/v or an amount of Carbopol ® 934 or 940 sufficient to achieve a viscosity of from about 5 to about 35 cps upon topical instillation, such as Carbopol® 940 at a concentration from about 0.09% to about 1.0% w/v;
- a phosphate, citrate, citrophosphate, or acetate buffer from about 3 to about 10 mM
- pH is from about 4.75 to about 6.0.
- compositions (Formulas #25 and #26).
- CAPB cocamidopropyl betaine
- Replacing polyoxyl 40 stearate with Captisol ® (sulfobutylether b-cyclodextrin) and adding mannitol achieves similar results in redness reduction as the addition of CAPB to polyoxyl 40 stearate but without the attendant ache resulting in the highest overall rating among aceclidine compositions (Formula #32).
- Captisol ® sulfobutylether b-cyclodextrin
- aceclidine at a concentration of about 1.40%- 1.80% w/v;
- polyoxyl 40 stearate at about 5.5% w/v;
- mannitol at a concentration of about 2.5% to 4.5% w/v;
- carbomer 940 at a concentration of about 0.09% to about 2.0% w/v;
- a preservative such as BAK at a concentration of about 0.2% w/v; optionally citrate at a concentration of about 0.1%;
- acetate or phosphate buffer at 2-100 mM, more preferably 3-5 mM
- composition has a pH of about 4.50 to about 5.0; and preferably, about 4.75 to about 5.0; and
- a composition as described above was administered to a 62 year old subject. It resulted in pupils of 1.8-1.9 mm ou, 20.20 + reading vision, and 20.20 + distance vision; whereas without carbomer 940 reduced effectiveness resulted at 2.5% mannitol, and no near vision effect resulted at 4.0% mannitol. No ciliary spasm or loss of distance vision resulted. Onset was within about 15 minutes. Transient redness of about 1+ /out of 4 was noted for about 20 minutes without alpha agonist vasoconstrictor. The presence or absence of BAK had no clinical effect, and was used to provide an optional preservative.
- aceclidine at a concentration of about 1.50% w/v;
- polyoxyl 40 stearate at a concentration of about 5.5% w/v;
- mannitol at a concentration of about 2.5% w/v;
- citrate at a concentration of about 3 mM
- composition has a pH of about 4.75.
- Example 11 Use of compositions containing little or no cycloplegic agent
- Aceclidine alone causes incidence migraine- like severe ciliary spasm (brow ache) and myopic blur. These effects are inversely correlated to age with subjects age 40 reporting the highest incidence and subject age 60+ reporting the lowest incidence.
- the addition of a cycloplegic agent reduces ciliary spasms and attendant brow ache, migranious headache, squeezing pressure around eyes or other symptoms of ciliary spasms.
- the addition of the cycloplegic agent surprisingly, does not reduce the myopic effect of aceclidine.
- the addition of 2.5% w/v mannitol however does reduce the myopic effect of aceclidine.
- aceclidine concentration overcomes this reduction in myopic effect seen with the addition of mannitol. Surprisingly, however, the increase in aceclidine is not coincident with an increase in ciliary spasm. Even more surprising, the concentration of the cycloplegic agent can be reduced or even eliminated in the presence of mannitol without an increase in ciliary spasm . Thus, combining a higher concentration of aceclidine with little to no cycloplegic agent in the presence of mannitol results in an improvement of near vision acuity without attendant side effects on par with lower concentrations of aceclidine and higher concentrations of the cycloplegic agent in the absence of a cycloplegic agent.
- the addition of a nonionic surfactant increases both the quantitative measure of near vision improvement and the duration. This effect is concentration sensitive.
- the non-ionic surfactant is at least 1%, preferably at least 2%, more preferably from about 1% to about 5%, and most preferably about 5%.
- polysorbate 80 or polyoxyl 40 stearate at a concentration from about 1% to about 5% w/v results in about 1.5 to about 2.0 lines of improvement and a duration from about 4 to about 5 hours.
- the increase in concentration of a surfactant may crowd the surface of the cornea, and at an optimal concentration this crowding result in small and probably nanometer diameters, which given the dual polarity of surfactants, where nonionic are most preferred, enhances corneal absorption of the entrapped highly polar aceclidine molecules.
- a viscosity enhancer in a formulation with optimal ratios of aceclidine, tropieamide and a non-ionic surfactant dramatically improves duration.
- a formulation of the present invention comprising 1.75% aceclidine, 2.5% mannitol, 0.01% tropieamide, 5% polysorbate 80 improves near vision in a presbyopic patient by up to 3 lines of vision acuity for about 4 to about 5 hours.
- the addition of 1.4% CMC further increases the near vision improvement to from about 7 to about 10 hours.
- a threshold above the critical micellar threshold greatly enhances permeation through the cornea by reducing micelle size from micrometers to nanometers. See Figure 2.
- compositions containing little or no cycloplegic agent are shown in Table 8 below.
- mm denotes millimeter
- %* denotes amount can optionally vary from about 0.01% to about 1% w/v.
- # denotes formulation can include polysorbate 80 or not include polysorbate 80.
- the efficacy index is demonstrated in Figure 3.
- the score is calculated by multiplying the lines of improvement in near visual acuity by the number of hours the improvement lasts. For example a score of: 5 is equal to +1 lines of improvement in near visual acuity for 5 hours; 10 is equal to +1.5 lines of improvement for 6.7 hours; 15 is equal to 2 lines of improvement for 7.5 hours; 20 is equal to 2.5 lines of improvement for 8 hours; 25 is equal to 3+ lines of improvement for 8.3 hours and 35 is equal to 3.75+ lines of improvement for 9 hours.
- formulas containing 1.75% aceclidine and 2.5% mannitol have an increased efficacy and duration in treating presbyopia that is correlated with an increase in polysorbate 80 up to 5.0% and then inversely correlated with a decrease in CMC from 1.45% to 1.40%
- Example 14 Use of a preferred embodiment optimizing tropicamide and hydroxypropyl methyl cellulose
- Comfort, duration and efficacy were assessed. Stinging upon instillation and over the first hour was minimal with a score of 0.25 out of 4. Redness over the first hour was also minimal with a score of 0.5 out of 4 assessed at 20 minutes. Onset of vision improvement occurred with the first 20 to 25 minutes after instillation. Baseline near vision (i.e. 40
- Table 10 lists the active ingredients, excipients and their concentrations for compositions with both tested and prophetic examples of nonionic surfactants.
- Comfort and duration for each non-ionic surfactant were also tested and are noted in Table 10. Stinging and Redness are based on a scale of 0 to 4 with 0 being none and 4 being the most severe. Other than Brij® 35 stinging and redness were mild to nearly absent. Duration was excellent for each nonionic surfactant tested.
- Example 16 Use of a compound containing optimizing nonionic surfactant and antioxidant additives and concentrations
- HPMC 1.25% w/v high MW equaling viscosity of about 400 eps units
- Comfort, duration and efficacy were assessed. Stinging upon instillation and over the first hour was minimal for each subject with a score of 0.50 out of 4 for about 15 seconds. Redness over the first hour was also minimal for each subject with a score of 0.25 out of 4 assessed at 20 minutes. Onset of vision improvement occurred with the first 20 to 25 minutes after instillation. For subject 1 baseline near vision (i.e. 40 centimeters) was improved by 4.0 - 4.25 lines of visual acuity and lasted for 11.5 hours. For subject 2 baseline near vision was improved by 3.5 lines of visual acuity and lasted for 9.5 hours. The Efficacy Index score was 47.38 and 33.25, among the highest achieved for any formulation.
- Example 17 Compositions for the treatment of presbyopia
- Example 18 Compositions for the treatment of presbyopia in a contact lens
- composition from Example 17, above will be embedded in a daily contact lens, preferably a silicone-hydrogel or hydrogel contact lens.
- the contact lens will be inserted into the eye of the 6 patients from Example 17.
- the 6 patients will experience an improvement over topical installation alone. For example, the patients will experience a 10%, 25% or even 40% increase in duration when inserting the contact lens embedded with the composition of Example 17 compared to topical installation.
- Example 19 A dual-chamber blister pack for storage of contact lens and a composition for treatment of presbyopia
- a blister pack comprises both the lyophilized composition and the vehicle composition in two separate chambers constructed of semi-rigid to rigid material separated by an inert foil tab.
- a daily wear contact lens resides in an upper chamber containing the vehicle composition. When the tab is pulled the vehicle drops from the upper chamber into the lypophilized aceclidine in the lower chamber, and is completely solubilized in about 30 to 60 seconds without agitation.
- the blister pack chambers are constructed of foil and are sealed with a foil or other seal and an inert plastic tab glued to both foil surfaces. Upon pulling the tab an opening is created allowing the compositions of the two chambers to be mixed regardless of which is the superior blister pack chamber.
