A method for reducing the transmittance of ultraviolet radiation through an intraocular lens to 10% or less at 370 nm by (a) polymerizing a mixture comprising: at least one first monomer and a 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 physical properties such as, for example, refractive index as the optic portion of the intraocular lens formed from the polymerized mixture of (a) without the second monomer, but otherwise identical conditions. 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.
一种将通过眼内透镜的紫外线辐射透过率在 370 纳米波长处降低到 10% 或更低的方法,其方法是:(a)聚合一种混合物,该混合物包括:至少一种第一单体和一种包含三芳基-
