Filed:

Jun 25, 1996

Appl. No.:

08/615185

Inventors:

Dennis Alexander Figueroa - Mission Viejo CA
Alok Nigam - Trabuco Cyn CA
Thomas Michael Heyman - Chino Hills CA

Assignee:

Bausch Lomb Surgical, Inc. - Rochester NY

International Classification:

A61F 900

US Classification:

606107, 623 643

Abstract:

An intraocular lens insertion device having a tubular member for receiving the lens and a plunger for pushing the lens into the eye. The lens is held in a suspended position by its haptics so that the optic portion of the lens does not contact the interior of the tubular member. The plunger tip is provided with a slot for holding the lens after it is expelled from the tubular member into the eye in order to alleviate the risks associated with uncontrolled unfolding of the lens or uncontrolled expulsion of the lens from the inserter into the eye.

Assignee:

Anamed, Inc. - Irvine CA

International Classification:

A61F 214

US Classification:

623 511, 623 516

Abstract:

Filed:

Nov 7, 2001

Appl. No.:

10/053178

Inventors:

Alok Nigam - Trabuco Canyon CA 92679

International Classification:

A61F 214

US Classification:

623 513, 623 516

Abstract:

A bio-compatible corneal ring for myopic correction and accommodation for presbyopia. The corneal ring is made from a bio-compatible material with a lens body having an inner and outer circular edge. The inner circular edge forms an opening in the lens body. The posterior surface of the lens body has a uniform radii of curvature between the inner and outer circular edges. The anterior surface has two radii of curvatures providing for correction of myopia. The first radii of curvature extends from near the outer circular edge to a junction point before the inner circular edge. The second radii of curvature extends from the junction point and continues to the inner circular edge. The inner and outer circular edges have a thickness of less than about 0. 020 mm, but preferably are about 0. 010 mm or less.
