Description

OPHTHALMIC LENS HAVING A YELLOW DYE LIGHT BLOCKING COMPONENT
CROSS-REFERENCE TO RELATED APPLICATION
The present Application claims the benefit of United States provisional patent application 61/028,038, filed February 12, 2008, entitled "Intraocular Lens With UV Absorber And Blue Blocker," the contents of which are incorporated herein by reference in their entirety.
FIELD OF THE INVENTION
This invention relates generally to ophthalmic lenses and, more specifically, to ophthalmic lenses comprising materials for blocking the transmission of certain light frequencies.
BACKGROUND OF THE INVENTION
Blue blocking (400-500 nm radiation) and violet blocking (4OO-44onm) chromophores have been incorporated into plastics used as ophthalmic lenses (e.g. spectacles, intraocular lenses and contact lenses). Blue blocking and violet blocking agents are reported to protect the retina against damaging higher energy visible light radiation. Ultraviolet blocking agents are also added to ophthalmic lenses to protect the retina against UV-A radiation. Together, blue blocker and UV absorber, absorb the damaging radiation spectrum that can potentially reach the retina.
US Patent 5470932, for example, teaches against the use of vinyl- functionalized dyes in acrylate-based polymer systems, recommending the use of acrylate polymerizable groups. The inventor argues that yellow dyes having acrylate or methacrylate functional groups are more efficiently bound by covalent bonds into acrylate polymers than a dye that has vinyl functionality. An example of a vinyl polymerizable dye cited in this patent, i.e., 4-phenylazophenol allyl ether, suggests that the formulation of such dyes is inefficient, in that a 44% absorption loss is reported after soxhlet extraction in acetone. Accordingly, there is a need for an ophthalmic lens light blocking system which avoids.the aforementioned problem in the prior art.
SUMMARY OF THE INVENTION
The invention satisfies this need. The invention is a polymeric ophthalmic lens material comprising a) one or more lens-forming polymerizable monomers selected from the group of hydrophilic acrylate-substituted monomers, hydrophobic acrylate-substituted monomers, vinyl-substituted monomers, and platinum-catalyzed vinyl hydride addition-cured silicones, b) a polymerizable ultraviolet absorber and c) a polymerizable yellow dye.
In one embodiment of the invention, the polymerizable ultraviolet absorber has the formula:
Figure imgf000004_0001
and the polymerizable yellow dye has the formula:
Figure imgf000004_0002
wherein Ri = vinyl, R2, R3 = H, alkyl,hydroxyalkyl, wherein R2 = vinyl, Ri, R3 = H, alkyljhydroxyalkyl, and wherein R3 = vinyl, R1, R2 = H, alkyl,hydroxyalkyl.
As used in this application, the phrase "wherein Ri = vinyl, R2, R3 = H, alkyl,hydroxyalkyl, wherein R2 = vinyl, R1, R3 = H, alkyl,hydroxyalkyl, and wherein R3 ; vinyl, R1, R2 = H, alkyl,hydroxyalkyl " is meant to describe the different structures as summarized in the following table:

These and other features, aspects and advantages of the present invention will become better understood with reference to the following description, appended claims and accompanying drawings where:
Figure 1 is a transmittance curve illustrating the blue blocking characteristics of a lens having features of the invention; and
Figure 2 is a transmittance curve illustrating the violet blocking characteristics of a lens having features of the invention. DETAILED DESCRIPTION
The following discussion describes in detail one embodiment of the invention and several variations of that embodiment. This discussion should not be construed, however, as limiting the invention to those particular embodiments. Practitioners skilled in the art will recognize numerous other embodiments as well.
The invention is a polymeric ophthalmic lens material comprising a) one or more lens-forming polymerizable monomers selected from the group of hydrophilic acrylate-substitute monomers, hydrophobic acrylate-substituted monomers, vinyl- substituted monomers, and platinum catalyzed vinyl hydride addition cured silicones, b) a polymerizable ultraviolet absorber and c) a polymerizable yellow dye.
Preferably, lenses made from the polymeric ophthalmic lens material of the invention are capable of blocking between about 40% and about 60%, preferably between about 50% and about 60%, of light having a wavelength of 450 nm.
In one embodiment of the invention, the polymerizable ultraviolet absorber has the formula:
Figure imgf000006_0001
and the polymerizable yellow dye has the formula:
Figure imgf000007_0001
wherein R1 = vinyl, R2, R3 = H, alkyl,hydroxyalkyl, wherein R2 = vinyl, Rx, R3 = H, alkyl,hydroxyalkyl, and wherein R3 = vinyl, R1, R2 = H, alkyl,hydroxyalkyl.
The preparation of 2-(5-Chloro-2H-benzotriazol-2-yl)-6-(i,i- dimethylethyl)-4- ethenylphenol is described in US Patent 4868251.
The preparation of the yellow dye (N-phenyl-4-(3-vinylphenylazo)- aniline) is also easily accomplished using procedures known to those skilled in the art. For example, to prepare the 3 vinyl diazonium salt, 3-vinyl aniline is dissolved in glacial acetic acid acidified with sulfuric acid and the solution is chilled to 5 SC. A pre- chilled aqueous solution of sodium nitrite is added dropwise to the vinyl aniline solution and the mixture is then stirred in an ice bath for 2.5 hours yielding a clear yellow solution of the 3-vinyl diazonium salt. This solution is then added dropwise to a pre-chilled (52C) methanol solution of diphenylamine solution. The reaction mixture is stirred overnight at room temperature. A dark purple fine suspension is formed. The solution is neutralized with sodium hydroxide, the raw product is collected as precipitate and redissolved in ether. The ether phase is first water washed and the raw product purified by silica gel column chromatography. The dye is recovered as an orange solid. Typically, the concentration of the ultraviolet absorber is between about 0.1% and about 1.0% on a weight to weight basis. Typically, the concentration of the yellow dye is between about 10 ppm and about 500 ppm on a weight to weight basis.
One formulation of a blue blocking lens has about 0.5% of the ultraviolet absorber with about 50 ppm of the yellow dye. The transmittance curve of a 1 mm thick hydrophobic acrylic lens made with this blue blocking formula is provided in Figure 1.
Another formulation of a violet blocking lens has about 0.75% of the ultraviolet absorber with 5 ppm of the yellow dye. The transmittance curve of a 1 mm thick hydrophobic acrylic lens made with this violet blocking formula is provided in Figure 2.
Other typical formulations of the invention have yellow dye concentrations as summarized in the following table:
Figure imgf000008_0001
Thus, it can be seen that the unique combination of ultraviolet absorber and yellow dye permits the use of low concentrations.to achieve the ultraviolet absorber requirement (> 99% absorption of ultraviolet light of wavelengths less than 400 nm) and violet or blue blocking requirements. The total concentration of vinyl- containing chromophore (ultraviolet absorber and yellow dye) is less than 0.5% in a blue blocking 1 mm thick hydrophobic acrylic lens with the transmittance curve in Figure 1. The concentration of yellow dye is about 50 ppm. Thus, the invention constitutes a highly efficient and flexible light absorbing system for retinal protection. The absorption characteristics of the invention permit effective blue blocking capability in thin lenses, i.e. 0.25 mm, at practicable chromophore concentrations. At 0.25 mm, the total concentration of vinyl-containing chromophore would not exceed 1.2% and the yellow dye concentration would be less than 250 ppm. The yellow dye is also covalently bound by a vinyl polymerizable group yet it undergoes only 0.5 % absorption loss from the material described in the above example following soxhlet extraction. This loss is significantly less than even those reported for the two acrylate/acrylamide polymerizable preferred compounds - disclosed in Jinkerson (i.e. N-2-[3-(2'-methylphenylazo)-4- hydroxylphenyl]ethylmethacrylamide and N-(4'-phenylazo)phenyl-2-bis-(2- methacrylo)ethylamine) where he reported absorption losses of 10 % and 1%, respectively for these compounds. The extremely low losses of chromophore in material after soxhlet extraction in the example below are indicative of high levels of covalent coupling into the polymer. Efficient coupling of the dye is attributed to the extremely low dye concentrations that are needed to meet either blue blocking or violet blocking requirements of optical lenses of typical thicknesses ranging from 0.2 mm to 2 mm.
EXAMPLE
The following example describes the forming of one embodiment of the invention wherein a blue blocking acrylic material with 0.5 per cent 2-(5-Chloro-2H- benzotriazol-2-yl)-6-(i,i-dimethylethyl)-4-ethenylphenol and 50 ppm 0.5% N-phenyl- 4-(3-vinylphenylazo)-aniline:
Blue Blocking Transparent Foldable Acrylic (BBTFA) Polymer: The N- phenyl-4-(3-vinylphenylazo)-aniline and 2-(5-Chloro-2H-benzotriazol-2-yl)-6-(i,i- dimethylethyl)-4-ethenylphenol, respectively were polymerized with other monomers to produce the BBTFA material. Ethyl methacrylate (70.7 gms), butyl acrylate (137.7 grams), N-benzyl-N-isopropyl acrylamide (39.5 grams), ethylene glycol dimethacrylate ( i5.6grams), azoisobutyronitrile (0.33 grams), 2-(5-chloro-2Hbenzotriazol-2-yl)-6- (i,i-dimethylethyl)-4-ethenylphenol (1.33 grams) and N-phenyl-4-(3-vinylphenylazo)- aniline (0.0133 grams) were mixed in a round bottom flask and deoxygenated with nitrogen gas for one hour. The liquid mixture was filtered and transferred into glass molds designed to produce 2 mm thick sheets. The glass molds were placed in a programmable oven and cured. The molds were rapidly heated to 6osC and left at this temperature for sixteen hours, and were then heated to 1402C and post cured for 8 hours. After demolding, buttons were cut from the sheet and lathed down to 1 mm thickness. The transmittance curve of the 1 mm thick sample is shown in Figure 1. Having thus described the invention, it should be apparent that numerous structural modifications and adaptations may be resorted to without departing from the scope and fair meaning of the instant invention as set forth hereinabove and as described herein below by the claims.
