    • An intraocular lens (20) for use as an artificial lens implant is disclosed. The intraocular lens includes a lens body (21) having first and second relatively rigid members (24) and (30). Hinges (40) and (45) provide means for resiliently cooperatively connecting the first section (24) to the second section (30). The first section (24) is foldable with respect to the second section (30), wherein the lens body (21) may be folded from an operational configuration to a smaller insertion configuration making implantation possible through a smaller cut in the cornea of the eye than would otherwise be possible and after insertion and upon release of the hinges (40) and (45) the lens body (21) returns to the operational configuration without further manipulation. Three embodiments of the intraocular lens (20), (50) and (80) are disclosed.
    • 公开了一种用作人造透镜植入物的眼内透镜(20)。 眼内透镜包括具有第一和第二相对刚性构件(24)和(30)的透镜体(21)。 铰链(40)和(45)提供用于将第一部分(24)弹性协作地连接到第二部分(30)的装置。 第一部分(24)相对于第二部分(30)是可折叠的,其中透镜体(21)可以从操作构型折叠到更小的插入结构,通过眼睛的角膜中较小的切口使得植入成为可能 否则可能并且在插入之后并且在释放铰链(40)和(45)时,透镜体(21)返回到操作构型而无需进一步的操纵。 公开了眼内透镜(20),(50)和(80)的三个实施例。

    • 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.
    • 一种通过(a)聚合混合物将通过眼内透镜的紫外线辐射的透射率降低到10%以下的方法,所述混合物包含:至少一种第一单体和包含三芳基-1,3,5-三嗪的第二单体 部分,(b)从共聚物形成光学部分,其中第二单体以总聚合物的约0.10重量%至约0.20重量%存在,并且其中眼内透镜的光学部分显示基本相同的物理性质,例如 例如,作为由没有第二单体的(a)的聚合混合物形成的眼内透镜的光学部分的折射率,但是其他相同的条件。 另外,通过可折叠眼内透镜防止在370nm处的至少90%的紫外线辐射的透射率的方法包括:(a)将包含4-(4,6-二苯基-1,3,5-三嗪) -2-基)-3-羟基苯氧基部分转化成至少一种聚合物,和(b)将聚合物形成适合用作眼内透镜的材料,其中包含4-(4,6-二苯基-1,3- ,5-三嗪-2-基)-3-羟基苯氧基部分占总干性聚合物的0.10〜0.15重量%。
