Abstract
A method for reducing the transmittance of ultraviolet radiation through an intraocular lens to 10% or less at 370 mm Additionally, a method for preventing the transmittance of at least 90% of ultraviolet radiation at 370 nm through a foldable intraocular lens comprising: (a) incorporating a monomer comprising a 4-(4,6-diphenyl-1,3,5-triazin-2-yl)-3-hydroxyphenoxy moiety into at least one polymer and (b) forming the polymer into a material suitable for use as an intraocular lens, wherein the monomer comprising a 4-(4,6-diphenyl-1,3,5-triazin-2-yl)-3-hydroxyphenoxy moiety comprises 0.10 to 0.15 weight percent of the overall dry polymer.

A method of making an intraocular lens capable of reducing the transmittance of ultraviolet radiation at 370 nm comprising:
- (a) polymerizing a mixture comprising:
- at least one first monomer and
- at least one second monomer comprising a trisaryl-1,3,5-triazine moiety,
- (b) forming an optic portion from the copolymer
- wherein the second monomer is present in an amount sufficient to reduce the transmittance of ultraviolet radiation at 370 nm to ten percent or less, and wherein the amount of the second monomer does not substantially affect a physical characteristic of the lens other than transmittance of ultraviolet radiation.
A method of making an intraocular lens capable of absorbing ultraviolet radiation at 370 nm comprising:
- (a) polymerizing a mixture comprising:
- at least one first monomer and
- at least one second monomer comprising a trisaryl-1,3,5-triazine moiety,
- (b) forming an optic portion from the copolymer
- wherein the second monomer is present in about 0.10 to about 0.20 percent by weight of the overall polymer and wherein the optic portion of the intraocular lens displays essentially the same refractive index as the optic portion of the intraocular lens formed from the polymerized mixture of (a) without the second monomer, but otherwise substantially identical conditions.
A method for increasing the extinction coefficient of a copolymer of ultraviolet radiation at 370 nm through an intraocular lens comprising:
- (a) incorporating a monomer comprising a 4-(4,6-diphenyl-1,3,5-triazin-2-yl)-3-hydroxyphenoxy moiety into at least one polymer and
- (b) forming the polymer into a material suitable for use as an intraocular lens, wherein the monomer comprising a 4-(4,6-diphenyl-1,3,5-triazin-2-yl)-3-hydroxyphenoxy moiety comprises 0.10 to 0.15 weight percent of the overall dry polymer.
A method for preventing the transmittance of at least 90% of ultraviolet radiation at 370 nm through a foldable intraocular lens comprising:
- (a) incorporating a monomer comprising a 4-(4,6-diphenyl-1,3,5-triazin-2-yl)-3-hydroxyphenoxy moiety into at least one polymer and
- (b) forming the polymer into a material suitable for use as an intraocular lens, wherein the monomer comprising a 4-(4,6-diphenyl-1,3,5-triazin-2-yl)-3-hydroxyphenoxy moiety comprises 0.10 to 0.15 weight percent of the overall dry polymer.
A foldable intraocular lens or lens blank comprising at least one copolymer comprising at least (a) one first monomer, and
- (b) a second monomer present in about 0.05 to about 0.20 percent by weight of the overall dry polymer comprising a 4-(4,6-diphenyl-1,3,5-triazin-2-yl)-3-hydroxyphenoxy moiety, wherein the foldable intraocular lens or lens blank absorbs the transmittance of at least 90% of ultraviolet radiation at 370 nm, and wherein the optic portion of the intraocular lens displays essentially the same refractive index as the optic portion of a intraocular lens formed from the polymerized mixture of (a) without the second monomer, but otherwise identical composition.
