摘要:
An intraocular lens for providing vision to a subject contains an optic, a supportstructure coupled to the optic. The intraocular lens also includes a texturedsurface and/or subsurface layer. The optic is disposed about an optical axisand comprises an anterior surface and an opposing posterior surface, the surfacesbeing configured to focus light when implanted within an eye having a capsularbag. The textured surface is disposed over a surface portion of the intraocularlens and includes a plurality of periodically- spaced protrusions, each protrusionhaving a smooth distal face and a sharp comer edge configured to engage a wall ofthe capsular bag and/or at least one cell disposed along the wall. The subsurfacelayer is configured to scatter an amount of light that is at least twice the amountof light scattered by portions of the material adjacent the subsurface layeror at least twice the amount of light scattered by another intraocular lens thatdoes not have the subsurface layer, but which is otherwise substantially equivalent.
