Claim:
A multifocal intraocular lens system for insertion of a multifocal intraocular lens into an artificial lens capsule for placement within an eye having a posterior chamber and an anterior chamber, said lens system comprising: a multifocal intraocular lens comprising a lens body having a substantially elliptical anterior surface with an upper portion and a lower portion, a substantially elliptical posterior surface with an upper portion and a lower portion, wherein the anterior surface is convex, the upper portion of the posterior surface is concave, and the lower portion of the posterior surface is convex, with an optical axis passing through the anterior surface and the posterior surface; wherein the lower portion of the anterior surface and the lower portion of the posterior surface meet at a bottom periphery, and the upper portion of the anterior surface and the upper portion of the posterior surface meet at a top periphery; said bottom edge having a semicircular or curved shape in cross-section along the optical axis, the lens body tapering upwards to create a tapering periphery at the top periphery, wherein the lower portion of the lens body is thicker than the upper portion of the lens body; and said upper portions of said anterior surface and said posterior surface each having at least one radius of curvature; an artificial lens capsule having an anterior surface and a posterior surface and adapted to be positioned within the eye, said lens body being disposed within said artificial lens capsule; a substance dispersed within said artificial lens capsule for allowing said lens body to move within said artificial lens capsule; and wherein said lens body is sized to encompass the optical axis of the eye depending upon the position of the eye.
