ABSTRACT:
An intraocular lens includes a lens body having a convex front surface and a planar back surface, an integral peripheral ring having an internal bevel extending rearwardly from the back surface, and four holes spaced about and adjacent the periphery of the lens body and extending from the front surface to the back surface. A pair of curved, filament members are attached to the lens body within apertures in bosses formed on the front surface of the lens body. Each filament member includes an inward u-niche and a distal closed loop. The u-niche makes for improved an easier insertion. The distal closed loop helps prevent iris entrapment and rupturing the posterior capsule.
