Silicone-Containing Contact Lens Polymers, Oxygen Permeable Contact Lenses And Methods For Making These Lenses And Treating Patients With Visual Impairment
US Patent:
5331067, Jul 19, 1994
Filed:
Jan 12, 1993
Appl. No.:
8/003535
Inventors:
Leonard Seidner - Brooklyn NY
Harry J. Spinelli - Wilington DE
Mohammed I. Ali - Aberdeen NJ
Lester Weintraub - Mount Laurel NJ

Assignee:
Permeable Technologies, Inc. - Morganville NJ
International Classification:
C08F28300
US Classification:
525479
Abstract:
The present invention relates to novel copolymers and contact lenses made from these copolymers comprising preformed silicon-containing acrylic star polymers and macromonomers, preparation of these contact lenses and a therapeutic method for treating patients with visual impairment. Described is a copolymer comprising at least about 10% by weight of a preformed silicone-containing acrylic copolymer and no more than about 90% by weight of a matrix formed from the random polymerization of a mixture of monomers. The mixture of monomers comprises at least one monomer selected from the group consisting of silicone acrylates, esters of alpha, beta-unsaturated acids and wetting monomers. The preformed silicone-containing acrylic copolymer is preferably copolymerized throughout the matrix. The copolymer is readily machined into gas permeable contact lenses exhibiting substantially enhanced characteristics of at least one of the characteristic group of oxygen permeability, hardness and machineability relative to contact lenses formed from the random polymerization of monomers.
