[0002] FIELD OF THE INVENTION The present invention relates to UV and high-energy visible light absorbers. More specifically, the present invention relates to compounds having polymerizable functional groups that absorb UV and / or high-energy visible light at various wavelengths and are optically transparent when incorporated into articles. Thus, the compounds can be used in polymeric articles, including biomedical devices such as ophthalmic devices. [Background technology]
[0003] High-energy light from the sun, such as UV light and high-energy visible light, is known to be involved in cell damage. While most radiation with wavelengths below 280 nm is absorbed by the Earth's atmosphere, photons with wavelengths in the 280-400 nm range have been linked to degenerative changes in the cornea and several eye disorders, including age-related cataracts and macular degeneration. (See Statement on Ocular Ultraviolet Radiation Hazards in Sunlight, American Optometric Association, November 10, 1993.) The human cornea absorbs some radiation up to 320 nm (30% transmission) (Doutch, JJ, Quantock, AJ, Joyce, NC, Meek, KM, Biophys. J, 2012, 102, 1258-1264), but is inefficient at protecting the back of the eye from radiation in the 320-400 nm wavelength range.
[0004] Contact lens standards define the upper ultraviolet wavelength at 380 nm. The current Class I UV absorption standard defined by the American Optometric Association requires that >99% of radiation between 280 and 315 nm (UV B) and >90% of radiation between 316 and 380 nm (UV A) be absorbed by contact lenses. While this standard effectively addresses corneal protection (<1% UV B transmittance), little attention is paid to lower-energy UV radiation (>380 and <400 nm) associated with retinal damage (Ham, W.T., Mueller, H.A., Sliney, D.H. Nature 1976;260(5547):153-5) or high-energy visible light.
[0005] High-energy visible (HEV) light can cause visual discomfort or disrupt circadian rhythms. For example, computer and electronic device screens, flat-screen televisions, energy-efficient lights, and LED lights are known to emit HEV light. Long-term exposure to such HEV light sources can cause eye strain. Viewing devices that emit HEV light at night is also thought to disrupt natural circadian rhythms, leading to, for example, sleep deprivation.
[0006] Absorption of high-energy light rays before they reach the eye remains a desirable goal in ophthalmology. However, the degree to which certain wavelength ranges are absorbed is also important. For example, in the UV-A and UV-B ranges, it may be desirable to absorb as much radiation as possible. On the other hand, because HEV light forms part of the visible spectrum, complete absorption of HEV light may have adverse effects on vision. Therefore, partial absorption of HEV light may be more desirable. Summary of the Invention [Problem to be solved by the invention]
[0007] There is a need for materials that provide targeted absorption of undesirable wavelengths of high-energy radiation and that can be processed into functional products. Compounds that absorb or attenuate high-energy radiation, when used in ophthalmic devices, can help protect the cornea, as well as internal cells in the ocular environment, from deterioration, fatigue, and / or circadian rhythm disruption. [Means for solving the problem]
[0008] The present invention relates to high-energy light absorbing compounds that absorb UV and / or high-energy visible (HEV) light but substantially transmit (e.g., greater than 80% transmittance) wavelengths longer than about 450 nm. The compounds are therefore effective in providing targeted absorption of high-energy light, such as UV (UV A and UV B), low-energy UV light (385 nm to 400 nm), or HEV light (e.g., 400 to 450 nm).
[0009] The compounds are also polymerizable and generally compatible with the polymerization and processing conditions typically used to make ophthalmic devices such as soft contact lenses, in addition to other raw materials, and therefore can be easily covalently incorporated into final products without requiring significant modifications to existing manufacturing processes and equipment.
[0010] Thus, in one aspect, the present invention provides a compound of formula I:
[0011] [ka] provide During the ceremony, m and n are independently 0, 1, 2, 3, or 4; T is a bond, O, or NR; X is O, S, NR, SO, or SO; Y is a linking group, P g is a polymerizable group, R, at each occurrence, is independently H, C1-C6 alkyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, or YP g and R 1 and R 2 is, when present, independently at each occurrence C1-C6 alkyl, C1-C6 alkoxy, C1-C6 thioalkyl, C3-C7 cycloalkyl, aryl, halo, hydroxy, amino, NR 3 R 4 or benzyl, where R 3 and R 4 are independently H or C1-C6 alkyl, or two adjacent R 1 or R 2 the groups, together with the carbon atoms to which they are attached, are joined to form a cycloalkyl or aryl ring; The EWG is an electron-withdrawing group such as cyano, amide, ester, keto, or aldehyde (preferably cyano).
[0012] In another aspect, the present invention provides an ophthalmic device that is a free radical reaction product of a reactive mixture comprising one or more monomers suitable for making an ophthalmic device and a polymerizable high-energy light absorbing compound comprising a compound of Formula I described herein.
[0013] In a further aspect, the present invention provides a method of making an ophthalmic device, the method comprising: (a) providing a reactive mixture containing a compound of Formula I described herein, one or more device-forming monomers, and a radical initiator; and (b) polymerizing the reactive mixture to form the ophthalmic device.
[0014] In still a further aspect, the present invention provides an ophthalmic device that is a reaction product of a reactive mixture, the ophthalmic device comprising a polymerizable high-energy light absorbing compound and one or more monomers suitable for making an ophthalmic device, the ophthalmic device transmitting no more than 45 percent of light having a wavelength between 280 and 399 nm, between 1 percent and 70 percent of light having a wavelength between 400 and 409 nm, and at least 80 percent of light having a wavelength between 450 and 800 nm.
[0015] In a further aspect, the present invention provides an ophthalmic device that is a polymerization reaction product of a reactive mixture that includes one or more reactive components (such as a hydrophilic component and a silicone-containing compound), wherein the polymerization reaction product includes, as covalently attached substituents, one or more chromophores of Formula IV:

[0018] It is to be understood that the invention is not limited to the details of construction or process steps set forth in the following description, as the invention is capable of other embodiments and of being practiced or carried out in various ways using the teachings set forth herein.
[0019] As mentioned above, in one aspect, the present invention provides a UV / HEV absorbing compound. The compound contains a polymerizable functional group. It has been discovered that ophthalmic devices that absorb a significant amount of UV light as well as some amount of HEV light can be readily prepared as described herein.
[0020] It has also been discovered that light-absorbing compounds can be selected to provide targeted absorption of UV and / or high-energy visible light (e.g., increased UV absorption and decreased HEV absorption, or increased HEV absorption). Such targeting can be achieved, for example, using compounds of Formula I containing a heterotricyclic core chromophore. For example, as described in more detail below, compounds of Formula I in which the heteroatom (X in Formula I) is sulfur can absorb HEV light. On the other hand, compounds of Formula I in which the heteroatom is oxygen (X is O) can absorb less HEV light but more UV light. Thus, the compounds can be used to absorb selected regions of UV and / or HEV light, or can be mixed together or with other absorbing compounds to provide broad-spectrum protection (e.g., UV and HEV light). Advantageously, the compounds exhibit a transmission cutoff (e.g., absorb 20 percent or less) at visible wavelengths of 450 nm or greater.
[0021] The compounds of Formula I have further been found to be substantially photostable, meaning that when incorporated into an ophthalmic device, the compounds do not undergo significant degradation over time when exposed to lighting, such as indoor or outdoor lighting. Such photostability can be determined by measuring the UV / Vis transmittance spectrum of the ophthalmic device over a test period, such as 21 weeks. A significant change in the spectrum over the test period indicates a lack of photostability. By way of example, an ophthalmic device (such as a contact lens) containing a compound of the present invention exhibits a change in its average transmittance of no more than 5%, preferably no more than 2%, more preferably no more than 0.5%, and even more preferably no more than 0.4% over the wavelength range of 380-700 nm when exposed to indoor office lighting at room temperature for 21 weeks. As a further example, an ophthalmic device (such as a contact lens) containing a compound of the present invention exhibits a change in its average transmittance of no more than 5%, preferably no more than 2%, more preferably no more than 1%, and even more preferably no more than 0.7% over the wavelength range of 400-500 nm when exposed to indoor office lighting at room temperature for 21 weeks. Such changes can be calculated as the absolute difference between the mean transmittance (over a specified wavelength range) at 21 weeks and at time zero.
[0022] Thus, the compounds of the present invention are transparent in the visible spectrum but can successfully absorb UV (UVA, UVB) and / or HEV radiation, making them suitable for incorporation into a variety of products, including biomedical and ophthalmic devices.
[0023] The following definitions are provided for terms used in this disclosure.
[0024] Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention belongs. The definition of polymer is consistent with the definition disclosed in Compendium of Polymer Terminology and Nomenclature, IUPAC Recommendations 2008, edited by: Richard G. Jones, Jaroslav Kahovec, Robert Stepto, Edward S. Wilks, Michael Hess, Tatsuki Kitayama, and W. Val Metanomski. All publications, patent applications, patents, and other references mentioned herein are incorporated by reference.
[0025] As used herein, the term "(meth)" refers to any methyl substitution. Thus, a term such as "(meth)acrylate" refers to both methacrylate and acrylate.
[0026] Wherever a chemical structure is depicted, it should be understood that the disclosed options for substituents in the structure may be combined in any combination. * and R ** and each of these contains a list of three possible groups, then nine combinations are disclosed. The same is true for combinations of properties.
[0027] General formula [ *** ] n When a subscript, such as "n" in {overscore (R)} is used to denote the number of repeating units in a chemical formula of a polymer, the formula should be interpreted as representing the number average molecular weight of the polymer.
[0028] The term "individual" includes humans and vertebrates.
[0029] The term "biomedical device" refers to any article designed to be used in or on mammalian tissue or fluid, preferably human tissue or fluid. Examples of these devices include, but are not limited to, wound dressings, sealants, tissue prostheses, drug delivery systems, coatings, adhesion barriers, catheters, implants, stents, and ophthalmic devices such as intraocular lenses and contact lenses. The biomedical device may be an ophthalmic device, specifically a contact lens, most specifically a contact lens made from a silicone hydrogel or a conventional hydrogel.
[0030] The term "ocular surface" includes the surface and glandular epithelium of the cornea, conjunctiva, lacrimal gland, accessory lacrimal gland, nasolacrimal duct, and meibomian gland, as well as their apical and basal matrices, puncta, and adjacent or associated structures, including the eyelids, which are connected as a functional system by both epithelial continuity through innervation and by the endocrine and immune systems.
[0031] The term "ophthalmic device" refers to any apparatus that resides in or on the eye or any part of the eye (including the ocular surface). These devices can provide optical correction, appearance enhancement, vision enhancement, therapeutic effects (e.g., as a bandage), or delivery of active ingredients such as pharmaceutical and nutritional supplements, or any combination of the foregoing. Examples of ophthalmic devices include, but are not limited to, lenses, optics, and ocular inserts (including, but not limited to, punctal plugs). "Lens" includes soft contact lenses, hard contact lenses, hybrid contact lenses, intraocular lenses, and overlay lenses. Ophthalmic devices can include contact lenses.
[0032] The term "contact lens" refers to an ophthalmic device that can be placed on the cornea of an individual's eye. Contact lenses can provide corrective, cosmetic, or therapeutic benefits, including wound healing, delivery of medications or nutritional supplements, diagnostic evaluation or monitoring, ultraviolet absorption, visible light or glare reduction, or any combination thereof. Contact lenses can be of any suitable material known in the art and can be soft lenses, hard lenses, or hybrid lenses containing at least two distinct portions with different physical, mechanical, or optical properties, such as modulus of elasticity, water content, light transmission, or a combination thereof.
[0033] The biomedical devices, ophthalmic devices, and lenses of the present invention may be composed of silicone hydrogels or conventional hydrogels, which typically contain at least one hydrophilic monomer and at least one silicone-containing component covalently bonded to each other within the cured device.
[0034] "Target macromolecule" means a macromolecule that has been synthesized from a reactive monomer mixture, including monomers, macromers, prepolymers, crosslinkers, initiators, additives, diluents, and the like.
[0035] The term "polymerizable compound" means a compound containing one or more polymerizable groups. This term includes, for example, monomers, macromers, oligomers, prepolymers, crosslinkers, and the like.
[0036] A "polymerizable group" is a group capable of undergoing chain growth polymerization, such as a carbon-carbon double bond that can polymerize when subjected to free radical and / or cationic polymerization, e.g., radical polymerization initiation conditions. Non-limiting examples of free radical reactive groups include (meth)acrylate, styrene, vinyl ether, (meth)acrylamide, N-vinyl lactam, N-vinyl amide, O-vinyl carbamate, O-vinyl carbonate, and other vinyl groups. Preferably, the free radical polymerizable group comprises (meth)acrylate, (meth)acrylamide, N-vinyl lactam, N-vinyl amide, and styryl functional groups, as well as mixtures of any of the foregoing. More preferably, the free radical polymerizable group comprises (meth)acrylate, (meth)acrylamide, and mixtures thereof. The polymerizable group may be unsubstituted or substituted. For example, the nitrogen atom in (meth)acrylamide may be bonded to hydrogen, or the hydrogen may be substituted with alkyl or cycloalkyl (which may themselves be further substituted).
[0037] Any type of free radical polymerization can be used, including but not limited to bulk, solution, suspension, and emulsion, as well as any controlled radical polymerization method, such as stable free radical polymerization, nitroxide-mediated living polymerization, atom transfer radical polymerization, reversible addition-fragmentation chain transfer polymerization, organotellurium-mediated living radical polymerization, etc.
[0038] A "monomer" is a monofunctional molecule that can undergo chain growth polymerization, particularly free radical polymerization, thereby creating repeating units within the chemical structure of a target macromolecule. Some monomers have difunctional impurities that can act as crosslinkers. A "hydrophilic monomer" is also a monomer that, when mixed with deionized water at a concentration of 5% by weight at 25°C, gives a clear, single-phase solution. A "hydrophilic component" is a monomer, macromer, prepolymer, initiator, crosslinker, additive, or polymer that, when mixed with deionized water at a concentration of 5% by weight at 25°C, gives a clear, single-phase solution. A "hydrophobic component" is a monomer, macromer, prepolymer, initiator, crosslinker, additive, or polymer that is slightly soluble or insoluble in deionized water at 25°C.
[0039] A "macromolecule" is an organic compound having a number average molecular weight greater than 1500, and may be reactive or non-reactive.
[0040] A "macromonomer" or "macromer" is a macromolecule having one group capable of undergoing chain-growth polymerization, particularly free-radical polymerization, thereby creating repeating units within the chemical structure of a target macromolecule. Generally, the chemical structure of a macromer differs from that of a target macromolecule; i.e., the repeating units of the pendant group of the macromer differ from the repeating units of the target macromolecule or its backbone. The only differences between a monomer and a macromer are the chemical structure of the pendant group, the molecular weight, and the molecular weight distribution. Consequently, and as used herein, patent literature sometimes defines a monomer as a polymerizable compound having a relatively low molecular weight of about 1,500 daltons or less, which essentially includes some macromers. Specifically, monomethacryloxypropyl-terminated, mono-n-butyl-terminated polydimethylsiloxane (molecular weight = 500-1500 g / mol) (mPDMS) and mono-(2-hydroxy-3-methacryloxypropyl)-propyl ether-terminated, mono-n-butyl-terminated polydimethylsiloxane (molecular weight = 500-1500 g / mol) (OH-mPDMS) may be referred to as monomers or macromers. Furthermore, the patent literature sometimes defines macromers as having one or more polymerizable groups, essentially expanding the general definition of macromer to include prepolymers. Consequently, and as used herein, difunctional and multifunctional macromers, prepolymers, and crosslinkers may be used interchangeably.
[0041] A "silicone-containing component" is a monomer, macromer, prepolymer, crosslinker, initiator, additive, or polymer in a reactive mixture that has at least one silicon-oxygen bond, usually in the form of a siloxy group, a siloxane group, a carbosiloxane group, and mixtures thereof.
[0042] Examples of silicone-containing components useful in the present invention are disclosed in U.S. Pat. Nos. 3,808,178, 4,120,570, 4,136,250, 4,153,641, 4,740,533, 5,034,461, 5,070,215, 5,244,981, 5,314,960, 5,331,067, 5,371,147, 5,760,100, 5,849,811, 5,96 No. 2,548, No. 5,965,631, No. 5,998,498, No. 6,367,929, No. 6,822,016, No. 6,943,203, No. 6,951,894, No. 7,052,131, No. No. 7,247,692, No. 7,396,890, No. 7,461,937, No. 7,468,398, No. 7,538,146, No. 7,553,880, No. 7,572,841, No. 7,666,921 , No. 7,691,916, No. 7,786,185, No. 7,825,170, No. 7,915,323, No. 7,994,356, No. 8,022,158, No. 8,163,206, No. 8,273, No. 802, No. 8,399,538, No. 8,415,404, No. 8,420,711, No. 8,450,387, No. 8,487,058, No. 8,568,626, No. 8,937,110, No. 8,9 37,111, 8,940,812, 8,980,972, 9,056,878, 9,125,808, 9,140,825, 9,156,934, 9,170,349, 9,217,813, 9,244,196, 9,244,197, 9,260,544, 9,297,928, 9,297,929, and European Patent No. 080539. These patents are incorporated herein by reference in their entirety.
[0043] A "polymer" is a target macromolecule made up of repeating units of the monomers used during polymerization.
[0044] A "homopolymer" is a polymer made from one monomer; a "copolymer" is a polymer made from two or more monomers; and a "terpolymer" is a polymer made from three monomers. A "block copolymer" consists of compositionally distinct blocks or segments. A diblock copolymer has two blocks. A triblock copolymer has three blocks. A "comb or graft copolymer" is made from at least one macromer.
[0045] A "repeating unit" is the smallest group within a polymer that corresponds to the polymerization of a particular monomer or macromer.
[0046] An "initiator" is a molecule that can decompose into radicals that can subsequently react with monomers to initiate a free-radical polymerization reaction. Thermal initiators decompose at a specific rate depending on the temperature, and typical examples are azo compounds such as 1,1'-azobisisobutyronitrile and 4,4'-azobis(4-cyanovaleric acid); peroxides such as benzoyl peroxide, tert-butyl peroxide, tert-butyl hydroperoxide, tert-butyl peroxybenzoate, dicumyl peroxide, and lauroyl peroxide; peracids such as peracetic acid and potassium persulfate; and various redox systems. Photoinitiators decompose by a photochemical process, and typical examples are derivatives of benzil, benzoin, acetophenone, benzophenone, camphorquinone, and mixtures thereof, as well as various monoacyl and bisacylphosphine oxides and combinations thereof.
[0047] A "crosslinker" is a di- or polyfunctional monomer or macromer that can undergo free radical polymerization at two or more positions on the molecule, thereby creating branch points and polymer networks. Common examples are ethylene glycol dimethacrylate, tetraethylene glycol dimethacrylate, trimethylolpropane trimethacrylate, methylene bisacrylamide, triallyl cyanurate, etc.
[0048] A "prepolymer" is a reaction product of monomers that contain remaining polymerizable groups that can undergo further reaction to form a polymer.
[0049] A "polymer network" is a cross-linked macromolecule that can swell but cannot be dissolved in a solvent. A "hydrogel" is a polymer network that swells in water or an aqueous solution, typically absorbing at least 10% by weight of water. A "silicone hydrogel" is a hydrogel made from at least one silicone-containing component together with at least one hydrophilic component. The hydrophilic component may also include a non-reactive polymer.
[0050] "Conventional hydrogel" refers to a polymer network made from components that do not have any siloxy, siloxane, or carbosiloxane groups. Conventional hydrogels are prepared from reactive mixtures that include hydrophilic monomers. Examples include 2-hydroxyethyl methacrylate ("HEMA"), N-vinylpyrrolidone ("NVP"), N,N-dimethylacrylamide ("DMA"), or vinyl acetate. U.S. Patent Nos. 4,436,887, 4,495,313, 4,889,664, 5,006,622, 5,039459, 5,236,969, 5,270,418, 5,298,533, 5,824,719, 6,420,453, 6,423,761, 6,767,979, 7,934,830, 8,138,290, and 8,389,597 disclose the formation of conventional hydrogels.

[0052] An "interpenetrating polymer network" comprises two or more networks that are at least partially entangled on a molecular scale, but are not covalently bonded to each other and cannot be separated without interlocking chemical bonds. A "semi-penetrating polymer network" comprises one or more networks and one or more polymers characterized by some intermixing at the molecular level between at least one network and at least one polymer. A mixture of different polymers is a "polymer blend." Although a semi-penetrating network is technically a polymer blend, in some cases the polymers are entangled so that they cannot be easily removed.
[0053] The terms "reactive mixture" and "reactive monomer mixture" refer to a mixture of components (both reactive and non-reactive) that, when mixed together and subjected to polymerization conditions, form the biomedical devices, ophthalmic devices, and contact lenses made therefrom, in addition to conventional or inventive silicone hydrogels. Reactive monomer mixtures may include reactive components such as monomers, macromers, prepolymers, crosslinkers, and initiators; additives such as wetting agents, polymers, dyes; light-absorbing compounds such as UV absorbers, pigments, dyes, and photochromic compounds (all of which may be reactive or non-reactive but can be retained in the resulting biomedical devices, as well as pharmaceutical and nutraceutical compounds); and optional diluents.

[0128] Specific examples of compounds of Formula I include, but are not limited to, the compounds shown in Table 1.
[0129] [Table 1-1]
[0130] [Table 1-2]

[0134] [Table 1-6]
[0135] The compounds of the present invention can be selected to provide targeted absorption of UV and / or high-energy visible light. Such targeting can be achieved, for example, by selecting the heteroatom (X in Formula I) of the core tricyclic structure. For example, compounds of Formula I-1 (where the heteroatom is sulfur) can absorb HEV light. On the other hand, compounds of Formula I-2 (where the heteroatom is oxygen) can absorb UV light and some HEV light, although to a lesser extent than compounds of Formula I-1.
[0136] The absorption characteristics for a given X in a compound of formula I can be modified, for example, by changing the substituent R 1 and R 2 The absorption spectrum can be further adjusted by adding or modifying the substituents. Electron-donating substituents can cause, for example, a red shift in the UV-VIS absorption spectrum, while electron-withdrawing groups can cause a blue shift. The magnitude of these shifts can depend on the electron-donating or -withdrawing ability and position of the substituent. For example, an alkoxy substituent can cause a smaller red shift than, for example, an amino or thioalkyl group at the same carbon center.
[0137] Preferred X groups in the compounds of the present invention are S, O, and NR, more preferably S and O. However, further oxidation states of sulfur, such as sulfoxides and sulfones, may also provide a means of modifying the UV-VIS spectrum of the compounds. Sulfoxides and sulfones have reduced electron density on the sulfur atom and can be used to impart a hypsochromic (blue) shift to the spectrum.
[0138] The compound of Formula I can be used in combination with other absorbing compounds to provide desirable absorption properties. For example, a preferred composition may include a compound of Formula I-1 (where X is S) and a second compound that absorbs UV. The second compound may be, for example, a compound of Formula I that absorbs in the UV region (such as a compound of Formula I-2 (where X is O)), or it may be another UV-absorbing compound. Suitable UV-absorbing compounds are known in the art and fall into several categories, including, but not limited to, benzophenones, benzotriazoles, triazines, substituted acrylonitriles, salicylic acid derivatives, benzoic acid derivatives, cinnamic acid derivatives, chalcone derivatives, dipnone derivatives, crotonic acid derivatives, or any mixture thereof. A preferred class of UV-absorbing compounds are benzotriazoles, such as Norbloc (2-(2'-hydroxy-5-methacrylyloxyethylphenyl)-2H-benzotriazole).
[0139] A particularly preferred composition comprises 2-(2-cyano-2-(9H-thioxanthen-9-ylidene)acetamido)ethyl methacrylate and 2-(2-cyano-2-(9H-xanthen-9-ylidene)acetamido)ethyl methacrylate. Another preferred composition comprises 2-(2-cyano-2-(9H-thioxanthen-9-ylidene)acetamido)ethyl methacrylate and 2-(2'-hydroxy-5-methacrylyloxyethylphenyl)-2H-benzotriazole. A further preferred composition comprises N-(2-(2-cyano-2-(10-methylacridin-9(10H)ylidene)acetamido)ethyl)methacrylamide.

The acyclic polyamide may be any of the acyclic polyamides or copolymers thereof described herein, and the cyclic polyamide may be any of the cyclic polyamides or copolymers thereof described herein.

[0232] The total amount of all polyamides in the reactive mixture can be in the range of 1% to about 35% by weight, such as in the range of 1% to about 15% by weight, and in the range of about 5% to about 15% by weight, in all cases based on the total weight of the reactive components of the reactive monomer mixture.
[0233] Without being bound by theory, when used with silicone hydrogels, polyamides function as internal wetting agents. The polyamides of the present invention may be non-polymeric, in which case they are incorporated into the silicone hydrogel as a semi-interpenetrating network. The polyamides are encapsulated or physically held within the silicone hydrogel. Alternatively, the polyamides of the present invention may be polymeric, for example, as polyamide macromers or prepolymers, in which case they are covalently incorporated into the silicone hydrogel. Mixtures of polymeric and non-polymeric polyamides may also be used.
[0234] When a polyamide is incorporated into the reactive monomer mixture, the polyamide may have a weight average molecular weight of at least 100,000 daltons, greater than about 150,000, from about 150,000 to about 2,000,000 daltons, or from about 300,000 to about 1,800,000 daltons. High molecular weight polyamides can be used if they are compatible with the reactive monomer mixture.
[0235] Crosslinking agent It is generally desirable to add one or more crosslinking agents, also referred to as crosslinking monomers, multifunctional macromers, and prepolymers, to the reactive mixture. The crosslinking agent may be selected from difunctional, trifunctional, tetrafunctional crosslinkers, and mixtures thereof, including silicone-containing and non-silicone-containing crosslinkers. Non-silicone-containing crosslinkers include ethylene glycol dimethacrylate (EGDMA), tetraethylene glycol dimethacrylate (TEGDMA), trimethylolpropane trimethacrylate (TMPTMA), triallyl cyanurate (TAC), glycerol trimethacrylate, methacryloxyethyl vinyl carbonate (HEMAVc), allyl methacrylate, methylenebisacrylamide (MBA), and polyethylene glycol dimethacrylate, where the polyethylene glycol has a molecular weight of up to about 5000 daltons. The crosslinking agent is used in the reactive mixture in conventional amounts, for example, from about 0.000415 to about 0.0156 moles per 100 grams of reactive formulation. Alternatively, if the hydrophilic monomer and / or silicone-containing component is multifunctional due to molecular design or impurities, adding a crosslinker to the reactive mixture is optional. Examples of hydrophilic monomers and macromers that can act as crosslinkers and, if present, do not require the addition of additional crosslinkers to the reactive mixture include (meth)acrylate and (meth)acrylamide end-capped polyethers. Other crosslinkers will be known to those skilled in the art and can be used to prepare the silicone hydrogels of the present invention.
[0236] It may be desirable to select a crosslinker that has similar reactivity with one or more of the other reactive components in the formulation. In some cases, it may be desirable to select a mixture of crosslinkers with different reactivities to control some of the physical, mechanical, or biological properties of the resulting silicone hydrogel. The structure and morphology of the silicone hydrogel may also be affected by the diluent(s) and curing conditions used.
[0237] To further increase the modulus and maintain tensile strength, multifunctional silicone-containing components, including macromers, crosslinkers, and prepolymers, may also be included. Silicone-containing crosslinkers may be used alone or in combination with other crosslinkers. An example of a silicone-containing component that can act as a crosslinker and, when present, does not require the addition of a crosslinking monomer to the reactive mixture, is α,ω-bismethacryloylpropyl polydimethylsiloxane. Another example is bis-3-acryloxy-2-hydroxypropyloxypropyl polydimethylsiloxane (ac-PDMS).
[0238] Crosslinkers with rigid chemical structures and polymerizable groups capable of undergoing free radical polymerization can also be used. Non-limiting examples of suitable rigid structures include crosslinkers containing phenyl and benzyl rings, such as 1,4-phenylenediacrylate, 1,4-phenylenedimethacrylate, 2,2-bis(4-methacryloxyphenyl)-propane, 2,2-bis[4-(2-acryloxyethoxy)phenyl]propane, 2,2-bis[4-(2-hydroxy-3-methacryloxypropoxy)phenyl]propane, and 4-vinylbenzyl methacrylate, and combinations thereof. The rigid crosslinkers can be present in an amount of about 0.5 to about 15, or about 2 to 10, or 3 to 7, based on the total weight of all reactive components. The physical and mechanical properties of the silicone hydrogels of the present invention can be optimized for specific applications by adjusting the components in the reactive mixture.
[0239] Non-limiting examples of silicone crosslinkers also include the multifunctional silicone-containing components described above, such as compounds of Formula E (and subformulas thereof) and the multifunctional compounds shown in Table 3.

[0244] More preferred diluents include 3,7-dimethyl-3-octanol, 1-dodecanol, 1-decanol, 1-octanol, 1-pentanol, 1-hexanol, 2-hexanol, 2-octanol, 1-dodecanol, 3-methyl-3-pentanol, 1-pentanol, 2-pentanol, t-amyl alcohol, tert-butanol, 2-butanol, 1-butanol, 2-methyl-2-pentanol, 2-ethyl-1-butanol, 3,3-dimethyl-2-butanol, 2-octyl-1-dodecanol, mixtures thereof, and the like.
[0245] When a diluent is present, there is generally no particular limit as to the amount of diluent present. When a diluent is used, the diluent may be present in an amount ranging from about 2 to about 70 weight percent, such as from about 5 to about 50 weight percent and from about 15 to about 40 weight percent, based on the total weight of the reactive mixture (including reactive and non-reactive formulations). Mixtures of diluents may also be used.
[0246] A polymerization initiator may be used in the reactive mixture, and may include at least one of those that generate free radicals at moderately high temperatures, such as lauryl peroxide, benzoyl peroxide, isopropyl percarbonate, azobisisobutyronitrile, and photoinitiator systems, such as aromatic α-hydroxyketones, alkoxyoxybenzoins, acetophenones, acylphosphine oxides, bisacylphosphine oxides, and tertiary amines plus diketones, and mixtures thereof. Specific examples of photoinitiators include 1-hydroxycyclohexyl phenyl ketone, 2-hydroxy-2-methyl-1-phenyl-propan-1-one, bis(2,6-dimethoxybenzoyl)-2,4-4-trimethylpentylphosphine oxide (DMBAPO), bis(2,4,6-trimethylbenzoyl)-phenylphosphine oxide (Irgacure 819), 2,4,6-trimethylbenzyldiphenylphosphine oxide and 2,4,6-trimethylbenzoyldiphenylphosphine oxide, benzoin methyl ester, and a combination of camphorquinone and ethyl 4-(N,N-dimethylamino)benzoate.
[0247] Commercially available visible light initiator systems (manufactured by IGM Resins BV, The Netherlands) include Irgacure® 819, Irgacure® 1700, Irgacure® 1800, Irgacure® 819, Irgacure® 1850, and Lucrin® TPO initiators. Commercially available UV photoinitiators (manufactured by IGM Resins BV) include Darocur® 1173 and Darocur® 2959. These and other photoinitiators that can be used are disclosed in Volume III, Photoinitiators for Free Radical Cationic & Anionic Photopolymerization, 2nd Edition by J.V. Crivello & K. Dietliker; edited by G. Bradley; John Wiley and Sons; New York; 1998. The initiator is used in the reactive mixture in an amount effective to initiate photopolymerization of the reactive mixture, for example, from about 0.1 to about 2 parts by weight per 100 parts of the reactive monomer mixture. Polymerization of the reactive mixture can be initiated using heat, visible or ultraviolet light, or other means, appropriately selected depending on the polymerization initiator used. Alternatively, initiation can be carried out using an electron beam without a photoinitiator. However, when a photoinitiator is used, preferred initiators are bisacylphosphine oxides, such as bis(2,4,6-trimethylbenzoyl)-phenylphosphine oxide (Irgacure® 819) or a combination of 1-hydroxycyclohexyl phenyl ketone and bis(2,6-dimethoxybenzoyl)-2,4-4-trimethylpentylphosphine oxide (DMBAPO).

For the hydrophilic component, a mixture of DMA and HEMA is preferred. For the silicone-containing component, a mixture of SiMAA and mPDMS is preferred.
[0255] A preferred reactive mixture may include a high-energy light absorbing compound, such as a compound of Formula I, a hydrophilic component including a mixture of DMA and HEMA, and a silicone-containing component including a mixture of OH-mPDMS having 2 to 20 repeating units (preferably a mixture of 4 and 15 repeating units). Preferably, the reactive mixture further includes a silicone-containing crosslinker, such as ac-PDMS. Also preferably, the reactive mixture includes a wetting agent, preferably DMA, PVP, PVMA, or a mixture thereof.
[0256] A preferred reactive mixture comprises a high-energy light absorbing compound, such as a compound of Formula I, from about 1 to about 15 weight percent of at least one polyamide (e.g., an acyclic polyamide, a cyclic polyamide, or a mixture thereof), at least one first monofunctional hydroxyl-substituted poly(disubstituted siloxane) having 4 to 8 siloxane repeat units (e.g., OH-mPDMS, where n is 4 to 8, preferably n is 4), and at least one second hydroxyl-substituted poly(disubstituted siloxane) that is a monofunctional hydroxyl-substituted poly(disubstituted siloxane) having 10 to 200, or 10 to 100, or 10 to 50, or 10 to 20 siloxane repeat units (e.g., OH-mPDMS, where n is 10 to 20). 00, or 10-100, or 10-50, or 10-20, preferably n is 15), about 5 to about 35 weight percent of at least one hydrophilic monomer, and optionally a multifunctional hydroxyl-substituted poly(disubstituted siloxane) (e.g., ac-PDMS) having 10-200 or 10-100 siloxane repeat units.

[0257] The reactive mixture may contain optional ingredients such as, but not limited to, one or more initiators, internal wetting agents, crosslinkers, other UV or HEV absorbers, and diluents.
[0258] When copolymerized with other reactive components, compounds of Formula I provide polymerization products containing chromophore substituents. Such chromophore substituents can provide products with desirable light absorption properties, as described above. For example, ophthalmic devices, such as contact lenses, containing chromophore substituents can block undesirable high-energy light, as described in detail above. Accordingly, the present invention provides an ophthalmic device that is the polymerization reaction product of a reactive mixture (e.g., including a hydrophilic component and a silicone-containing compound), wherein the polymerization reaction product contains, as a covalently bonded substituent, one or more chromophores of Formula IV:
[0259] [ka] and an ophthalmic device comprising: wherein m and n are independently 0, 1, 2, 3, or 4; X is O, S, NR, SO, or SO; R, in each occurrence, is independently H, C1-C6 alkyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, or a bond to a polymerization reaction product; and R 1 and R 2 is, when present, independently at each occurrence C1-C6 alkyl, C1-C6 alkoxy, C1-C6 thioalkyl, C3-C7 cycloalkyl, aryl, halo, hydroxy, amino, NR 3 R 4 or benzyl, where R 3 and R 4 are independently H or C1-C6 alkyl, or two adjacent R 1 or R 2 The groups, together with the carbon atoms to which they are attached, are linked to form a cycloalkyl or aryl ring, and R 5is the bond to the polymerization reaction product, and EWG is an electron withdrawing group (preferably cyano).
[0260] In Formula IV, X is preferably O or S. In Formula IV, the bond to the polymerization reaction product preferably includes a residue of a polymerizable group and one or more of an alkylene group, a cycloalkylene group, a heterocycloalkylene group, an arylene group, a heteroarylene group, an oxaalkylene group, an alkylene-amide-alkylene group, or an alkylene-amine-alkylene group. Preferred polymerizable groups include styryl, vinyl carbonate, vinyl ether, vinyl carbamate, N-vinyl lactam, N-vinyl amide, (meth)acrylate, or (meth)acrylamide.
[0261] Preferred polymerization reaction products may further comprise one or more covalently bound UV-absorbing chromophores in addition to the chromophore of Formula IV. Preferred UV-absorbing chromophores include residues of benzophenones, benzotriazoles, triazines, substituted acrylonitriles, salicylic acid derivatives, benzoic acid derivatives, cinnamic acid derivatives, chalcone derivatives, dipnone derivatives, crotonic acid derivatives, or mixtures thereof.
[0262] Curing of Hydrogels and Lens Fabrication The reactive mixture may be formed by any method known in the art, such as by shaking or stirring, and used to form a polymeric article or device by known methods. The reactive components are mixed together, either with or without a diluent, to form the reactive mixture.
[0263] For example, an ophthalmic device can be prepared by mixing the reactive components and optionally diluent(s) with a polymerization initiator and curing under appropriate conditions to form a product that can later be formed into a suitable shape by lathing, cutting, etc. Alternatively, the reactive mixture can be placed in a mold and then cured into a suitable article.
[0264] A method of making a molded ophthalmic device such as a silicone hydrogel contact lens may include preparing a reactive monomer mixture, transferring the reactive monomer mixture to a first mold, placing a second mold over the first mold filled with the reactive monomer mixture, and curing the reactive monomer mixture by free radical copolymerization to form a silicone hydrogel in the shape of a contact lens.
[0265] The reactive mixture may be cured via any known process for shaping reactive mixtures in the production of contact lenses, including rotational molding and static molding. Rotational molding processes are disclosed in U.S. Patent Nos. 3,408,429 and 3,660,545, and static molding processes are disclosed in U.S. Patent Nos. 4,113,224 and 4,197,266. The contact lenses of the present invention may also be formed by direct molding of silicone hydrogels, which is economical and allows for precise control of the final shape of the hydrated lens. In this method, the reactive mixture is placed into a mold having the shape of the desired final silicone hydrogel, and the reactive mixture is subjected to conditions that polymerize the monomers, thereby producing a polymer of the approximate shape of the desired final product.
[0266] After curing, the lens may be subjected to extraction to remove unreacted components and remove the lens from the lens mold. Extraction may be performed using conventional extraction fluids, such as organic solvents such as alcohols, or may be extracted using aqueous solutions.
[0267] An aqueous solution is a solution containing water. The aqueous solution of the present invention may contain at least about 20% by weight water, or at least about 50% by weight water, or at least about 70% by weight water, or at least about 95% by weight water. The aqueous solution may also contain additional water-soluble ingredients, such as inorganic salts or release agents, wetting agents, slip agents, pharmaceutical ingredients, and nutritional supplements, or combinations thereof. A release agent is a compound or mixture of compounds that, when combined with water, reduces the time required to remove a contact lens from a mold compared to the time required to remove a contact lens using an aqueous solution without the release agent. The aqueous solution may not require special handling, such as purification, recycling, or special disposal.
[0268] Extraction can be accomplished, for example, by immersing the lens in an aqueous solution or by exposing the lens to a stream of aqueous solution. Extraction can also include, for example, one or more of: heating the aqueous solution; agitating the aqueous solution; increasing the concentration of a release agent in the aqueous solution to a level sufficient to cause lens release; mechanically or ultrasonically agitating the lens; and incorporating at least one filter aid or extraction aid into the aqueous solution to a concentration sufficient to facilitate adequate removal of unreacted components from the lens. The foregoing, with or without the addition of heat, vibration, or both, can be carried out in a batch or continuous process.
[0269] To facilitate leaching and demolding, it may be desirable to apply physical agitation. For example, the lens mold part to which the lens is attached can be vibrated or moved back and forth in the aqueous solution. Other methods may include passing ultrasound through the aqueous solution.
[0270] The lenses may be sterilized by known means, such as, but not limited to, autoclaving.
[0271] As noted above, the preferred ophthalmic device is a contact lens, more preferably a soft hydrogel contact lens. The transmission wavelengths and percentages described herein can be measured on lenses of various thicknesses, for example, using the methods described in the Examples. For example, preferred center thicknesses for measuring transmission spectra in soft contact lenses can be 80-100 micrometers, 90-100 micrometers, or 90-95 micrometers. Measurements can typically be performed at the center of the lens, using, for example, an instrument slit width of 4 nm. Various concentrations of one or more polymerizable high-energy light-absorbing compounds can be used to achieve the above transmission characteristics. For example, concentrations can range from at least 1 percent, or at least 2 percent, and up to 10 percent or up to 5 percent, based on the weight percent of all components in the reactive mixture excluding the diluent. Typical concentrations can range from 3 to 5%.
[0272] Silicone hydrogel ophthalmic devices (e.g., contact lenses) according to the present invention preferably exhibit the following properties. All values are preceded by "about," and the device can have any combination of the listed properties. Properties can be determined by methods known to those skilled in the art, for example, as described in U.S. Pregrant Publication No. 2018 / 0037690, which is incorporated herein by reference.
[0273] Water concentration %: at least 20%, or at least 25% and at most 80%, or at most 70% Haze: 30% or less, or 10% or less Kruss dynamic contact angle (°): 100° or less, or 50° or less Tensile modulus (psi): 120 or less, or 80 to 120 Oxygen permeability (Dk, Barrer): at least 80, or at least 100, or at least 150, or at least 200 Elongation at break: at least 100 With regard to ionic silicone hydrogels, the following properties (in addition to those mentioned above) may also be desirable: Lysozyme uptake (μg / lens): at least 100, or at least 150, or at least 500, or at least 700 Polyquaternium 1 (PQ1) uptake (%): 15 or less, or 10 or less, or 5 or less Some embodiments of the present invention will now be described in detail in the following examples. [Example]
[0274] Test Method The UV-visible spectra of compounds in solution were measured on a Perkin Elmer Lambda 45 or Agilent Cary 6000i UV / VIS scanning spectrometer. The instruments were allowed to thermally equilibrate for at least 30 minutes before use. For the Perkin Elmer instrument, the scan range was 200-800 nm, the scan speed was 960 nm per minute, the slit width was 4 nm, the mode was set to transmittance or absorbance, and baseline correction was selected. For the Cary instrument, the scan range was 200-800 nm, the scan speed was 600 nm / min, the slit width was 2 nm, the mode was set to transmittance or absorbance, and baseline correction was selected. Baseline correction was performed before analyzing samples using the autozero function.
[0275] The ultraviolet-visible spectra of partially formed contact lenses from the claimed compositions were measured using packing solutions on a Perkin Elmer Lambda 45 UV / VIS or Agilent Cary 6000i UV / VIS scanning spectrometer. The instruments were allowed to thermally equilibrate for at least 30 minutes before use. The Perkin Elmer instrument had a scan range of 200-800 nm, a scan speed of 960 nm per minute, a slit width of 4 nm, and the mode set to transmission, with baseline correction selected. Baseline correction was performed using a plastic two-piece lens holder and a cuvette containing the same solvent. These two-piece contact lens holders were designed to hold the sample in the quartz cuvette at a position traversed by the incident light beam. A reference cuvette also housed the two-piece holder. To ensure consistent sample thickness, all lenses were fabricated using the same mold. The central thickness of the contact lenses was measured using an electronic thickness gauge. The reported central thickness and transmittance spectra are obtained by averaging data from three individual lenses.
[0276] It is important to ensure that the exterior of the cuvette is completely clean and dry and that there are no air bubbles within the cuvette. Measurement reproducibility is improved when the reference cuvette and its lens holder remain constant and all samples use the same sample cuvette and its lens holder, ensuring that both cuvettes are properly inserted into the instrument.

[0278] Example 1 - Synthesis of 2-(2-cyanoacetamido)ethyl methacrylate (A) and 2-(2-cyano-2-(9H-thioxanthen-9-ylidene)acetamido)ethyl methacrylate (B) as shown in Scheme 2
[0279] [ka]
[0280] Methyl cyanoacetate (40 grams, 0.4037 moles) and 25 mL of dichloromethane were stirred in a three-necked 500 mL round-bottom flask equipped with a reflux condenser under a nitrogen atmosphere. After 2-aminoethanol (23.8 grams, 0.3897 moles, ∼0.97 equivalents) was added to the solution via an addition funnel, the temperature rose and the methylene chloride began to reflux. After the exotherm subsided, external heat was applied to maintain gentle reflux for a total of 2 hours, after which no ethanolamine was observed by thin-layer chromatography.
[0281] The reaction may also be carried out at room temperature and is complete within a few hours.
[0282] The mixture was cooled to room temperature, and all methylene chloride was evaporated under reduced pressure. The residual oil was washed three times with 50 mL of ethyl acetate to remove unreacted starting material and nonpolar impurities. The residual ethyl acetate was then removed under reduced pressure, and the resulting oil was used for acylation without further purification.
[0283] The crude N-2-hydroxyethylacetamide derivative was dissolved in 150 mL of dichloromethane containing 40 grams of pyridine (~0.5 moles) in a three-neck round-bottom flask equipped with a reflux condenser, an addition funnel, and a magnetic stir bar. The flask was immersed in an ice bath and cooled to approximately 0°C. Methacryloyl chloride (45.76 g, ~0.44 moles) was added dropwise through the addition funnel, and the resulting reactive mixture was allowed to warm to room temperature while constantly stirring the system. Methanol (20 mL) was added to the flask to quench any unreacted methacryloyl chloride. Volatile components were removed by rotary evaporation under reduced pressure, and the crude product was dissolved in 800 mL of dilute aqueous HCl. The resulting aqueous solution was extracted three times with 100 mL of hexane in a separatory funnel to remove any nonpolar impurities. The organic layer was discarded. Sodium chloride was added to the aqueous layer, which was then extracted three times with 300 mL of ethyl acetate. Approximately 50 milligrams of BHT was added as an inhibitor to the combined organic fractions, and the ethyl acetate was removed by rotary evaporation under reduced pressure. The crude product crystallized from solution during solvent removal. When approximately 100 mL of ethyl acetate remained in the flask, 250 mL of hexane was added, and the crude product was isolated by vacuum filtration using a fritted glass funnel. Thin-layer chromatography indicated the presence of a single compound. The filter cake was washed twice with 150 mL of hexane and then dried under vacuum at 40°C to yield 53 grams (approximately 70% yield) of 2-(2-cyanoacetamido)ethyl methacrylate (A). 1 H NMR(500MHz,CDCl3)δ 1.93(3H,s,CH3),3.36(2H,s,CNCH2),3.60(2H,dd,CH2NH),4.26(2H,t,CH2OC=O),5.59(1H,m,vinylic),6.11(1H,bs,vinylic),6.52(1H,bs,NH).
[0284] A mixture of 9H-thioxanthen-9-one (2.12 grams, 0.01 mole) and thionyl chloride (5 mL, 8.2 grams, ∼0.07 mole) was refluxed in a 50 mL round-bottom flask under a nitrogen atmosphere with constant stirring. After 2 hours, the red solution was evaporated to dryness to ensure all unreacted thionyl chloride was removed from the system. 2-(2-cyanoacetamido)ethyl methacrylate (A) (2.3 grams, 0.0117 mole, ∼1.17 equivalents) and 15 mL of dichloromethane were added, and the resulting reactive mixture was heated to reflux under a nitrogen blanket. The reaction was monitored by thin-layer chromatography. After 2 hours, no change in the chromatogram was observed, so the reactive mixture was cooled to room temperature. After passage through a short silica gel column (CHCl, followed by 8 wt% EtOAc in CHCl), 2-(2-cyano-2-(9H-thioxanthen-9-ylidene)acetamido)ethyl methacrylate (B) was isolated as yellow crystals (3.2 grams, 82% yield). The UV-VIS transmission spectrum of a 0.2 mM solution of compound B in methanol is shown in Figure 1. 1 H NMR(500MHz,CDCl3)δ 1.84(3H,s,CH3),3.47(2H,m,CH2NH),4.01(2H,t,CH2OC=O),5.55(1H,m,vinylic),5.91(1H,bs,NH),5.98(1H,bs,vinylic),7.2 4(1H,t,Ar-H),7.31(1H,t,Ar-H),7.39(2H,m,Ar-H),7.49(1H,d,Ar-H),7.55(1H,m,Ar-H),7.61(1H,d,Ar-H),8.04(1H,m,Ar-H).

[0287] A mixture of 9H-xanthen-9-one (5.0 grams, 0.0255 moles) and thionyl chloride (10 mL, 16.4 grams, 0.138 moles) was refluxed in a 50 mL round-bottom flask under a nitrogen atmosphere with constant stirring. After 3 hours, the red solution was evaporated to dryness to ensure all unreacted thionyl chloride was removed from the system. 2-(2-cyanoacetamido)ethyl methacrylate (A) (6.0 grams, 0.0306 moles, ∼1.2 equivalents) and 20 mL of dichloromethane were added, and the resulting reactive mixture was heated to reflux under a nitrogen blanket. The reaction was monitored by thin-layer chromatography. After 2.5 hours, the mixture was cooled to room temperature and passed through a short silica gel column (CHCl and ethyl acetate in CHCl) to purify 2-(2-cyano-2-(9H-xanthen-9-ylidene)acetamido)ethyl methacrylate (C). The off-white precipitate formed during rotary evaporation is washed with hexane and dried overnight in a vacuum oven at 40 °C. The UV-VIS transmission spectrum of compound (C) in a 0.2 mM methanol solution is shown in Figure 1. 1 H NMR(500MHz,CDCl3)δ 1.85(3H,s,CH3),3.60(2H,dd,CH2NH),4.2(2H,t,CH2OC=O),5.53(1H,t,vinylic),5.99(1H,bs,vinylic),6.17(1H,t,NH),7 .12(1H,t,Ar-H),7.29-7.34(3H,m,Ar-H),7.45(1H,ddd,Ar-H),7.52(1H,ddd,Ar-H),7.67(1H,dd,Ar-H),8.41(1H,dd,Ar-H).

[0290] A mixture of 10-methylacridin-9(10H)-one (2.09 grams, 0.01 mole) and thionyl chloride (5 mL, 8.2 grams, ∼0.07 mole) was refluxed in a 50 mL round-bottom flask under a nitrogen atmosphere with constant stirring. After 2 hours, the solution was evaporated to dryness to ensure all unreacted thionyl chloride was removed from the system. 2-(2-cyanoacetamido)ethyl methacrylate (A) (2.3 grams, 0.0117 mole, ∼1.17 equivalents) and 15 mL of dichloromethane were added, and the resulting reactive mixture was heated to reflux under a nitrogen blanket.

[0314] Example 9 - Silicone Hydrogel Formulations Containing Compound (B) Reactive monomer mixtures were prepared consisting of 77 weight percent of the formulation listed in Table 4 and 23 weight percent of diluent DO. The reactive monomer mixtures were individually filtered under pressure through 3 μm filters using stainless steel syringes.
[0315] [Table 4]
[0316] Formulations 9A-9D were degassed at ambient temperature by applying a vacuum (40 Torr) for 45 minutes. Then, in a glove box containing a nitrogen gas atmosphere and less than about 0.1-0.2 percent oxygen gas, approximately 75 μL of the reactive mixture was dispensed at room temperature using an Eppendorf pipette onto a FC made with a 90:10 (w / w) Zeonor / TT blend. A BC made with a 90:10 (w / w) Zeonor / TT blend was then placed onto the FC. The molds were equilibrated in the glove box for a minimum of 12 hours before pouring. Each pallet containing the eight mold assemblies was transferred to an adjacent glove box maintained at 65°C, with a luminance of approximately 2 mW / cm at the tray position. 2 The adhesive was cured from the top and bottom for 15 minutes using a 435 nm LED light with an intensity of 1000 uV.
[0317] With most of the lenses still attached to the FC, the lenses were manually removed from the molds and released by floating them in approximately 1 liter of 70 percent IPA for approximately 1 hour, followed by two 30-minute baths in fresh 70 percent IPA, two 15-minute baths in fresh DIW, and two 30-minute baths in packing solution. The lenses were equilibrated and stored in the borate-buffered packing solution. Those skilled in the art will appreciate that the exact lens demolding process, with respect to the concentration of the aqueous isopropanol, the number of washes with each solvent, and the duration of each step, can vary depending on the lens formulation and mold material. The objective of the lens demolding process is to demold all of the lenses without damage and to transition them from a diluent-swollen network to a packing-solution-swollen hydrogel. The average center thickness of each lens set was measured: 9A = 87.7 micrometers, 9B = 85.3 micrometers, 9C = 87.3 micrometers, and 9D = 85.7 micrometers.
[0318] Figures 3-5 show the UV-VIS spectra of lenses made from formulations 9A-9D, which demonstrate that compound (B) or a combination of compound (B) and Norbloc® can provide complete or near complete absorption from 300 nm to 400 nm, while providing some absorption in the high-energy visible region from 400 nm to 450 nm.
[0319] Example 10 - Silicone Hydrogel Formulations Containing Compounds (B) and (C) Reactive monomer mixtures were prepared consisting of 77 weight percent of the formulation listed in Table 5 and 23 weight percent of diluent DO. The reactive monomer mixtures were individually filtered under pressure through 3 μm filters using stainless steel syringes.
[0320] [Table 5]
[0321] Formulations 10A-10D were degassed at ambient temperature by applying a vacuum (40 Torr) for 45 minutes. Approximately 75 μL of the reactive mixture was then dispensed into a FC made with a 90:10 (w / w) Zeonor / TT blend using an Eppendorf pipette at room temperature in a glove box containing a nitrogen gas atmosphere and less than about 0.1-0.2 percent oxygen gas.

[0322] With most of the lenses still attached to the FC, the lenses were manually removed from the molds and released by floating them in approximately 1 liter of 70 percent IPA for approximately 1 hour, followed by two 30-minute soaks in fresh 70 percent IPA, two 15-minute soaks in fresh DIW, and two 30-minute soaks in packing solution. The lenses were equilibrated and stored in the borate-buffered packing solution. Those skilled in the art will appreciate that the exact lens demolding process, with respect to the concentration of the aqueous isopropanol, the number of washes with each solvent, and the duration of each step, can vary depending on the lens formulation and mold material. The goal of the lens demolding process is to release all of the lenses without damage and allow them to transition from a diluent-swollen network to a packing-solution-swollen hydrogel. The average center thickness of each lens set was measured: 10A = 93.7 micrometers, 10B = 93.7 micrometers, 10C = 95.3 micrometers, and 10D = 92.3 micrometers.
[0323] Figures 6-8 show UV-VIS spectra of lenses made from formulations 10A-10D, demonstrating that the combination of compounds (B) and (C) can provide complete or near complete absorption from 300 nm to 400 nm, while also providing some absorption in the high-energy visible region from 400 nm to 450 nm. The figures also show that compound (C) alone provides absorption in various wavelength ranges.
[0324] Example 11 Lenses were fabricated using a reactive monomer mix containing the components listed as 9D in Table 4 and the same curing and hydration process, except that the oxygen gas concentration in the glove box was less than 0.5%. The lenses were packaged in glass vials containing PS and then placed on a windowsill exposed to direct sunlight (11A) or on top of a cabinet with only indoor lighting and no exposure to direct sunlight (11B). Controls were stored in the dark. After 3, 5, 9, 15, and 21 weeks of exposure, the UV-visible transmittance spectra of the lenses were measured, as shown in Figures 9 and 10.
[0325] For lenses exposed to direct sunlight, the absorption of high-energy visible light between 400 and 450 nm did not change over time. The UV-VIS transmission spectrum between 450 and 700 nm changed only slightly (approximately 1%) over the test period.
[0326] For lenses exposed to indoor lighting, the absorption of high-energy visible light between 400 nm and 450 nm did not change over time. Over the test period, the UV-VIS transmission spectrum did not change by more than about 2% or 3% from 450 nm to 700 nm.
