Abstract
A method of manufacturing an intraocular lens for restoring visual function to an eye. The lens includes a convex lens optic for receiving and focusing light rays, a prismatic wedge adjacent to the convex lens optic for receiving and directing light rays to a functional portion of a retina of the eye, and structure for fixing the lens optic and the prismatic wedge in the eye so that the lens optic is angularly oriented with respect to an optic axis of the eye and is posterior to the prismatic wedge. The lens optic includes an aspheric surface having a geometry determined according to a specific formula.
