ABSTRACT:
An intraocular lens including a convex portion and a prismatic portion for use with patients having macular degeneration of the retina. The lens is to be implanted in the eye, after removal of the natural lens, to direct rays of light away from the diseased center of the retina and focus them on an undiseased area of the retina, thereby improving sight.
