Patent ID: 8192485

Claim:
A method of forming a replacement intraocular lens in situ in an eye comprising the steps of a) introducing a reversible hydrogel system in solution into the capsular bag, wherein the reversible hydrogel system comprises a copolymer, wherein said copolymer is a hydrogel when in an oxidized state, and is a solution when in a reduced state, and wherein said copolymer is produced by polymerization of a monomer with a disulfide crosslinker, said monomer being selected from the group consisting of acrylamide, N-ornithine acrylamide, N-(2-hydroxypropyl)acrylamide, hydroxy-ethylacrylate, hydroxyethylmethacrylate, polyethyleneglycol acrylates, polyethyleneglycol methacrylates, N-vinyl pyrrolidone, N-phenylacrylamide, dimethylaminopropyl methacrylamide, acrylic acid, benzylmethacrylamide, and methylthioethylacrylamide; and b) gelling the reversible hydrogel system.
