Patent ID: 8247511

Claim:
A method of manufacturing an intraocular lens comprising: providing a rigid copolymer comprising: a first monomer selected from the group consisting of ethylene glycol phenyl ether acrylate (EGPEA) and poly(ethylene glycol) phenyl ether acrylate ((polyEG)PEA); a second monomer selected from the group consisting of unsubstituted styrene and substituted styrene, wherein the substituent is selected from the group consisting of bromine, chlorine, iodine, lower alkyl and lower alkoxy; a third monomer comprising one ethylenic unsaturation that, if polymerized into a homopolymer, forms a high water content hydrogel; optionally, a cross-linking agent; machining the rigid copolymer into a rigid intraocular lens having desired dimensions; and, hydrating the rigid intraocular lens to form a foldable intraocular lens, wherein: the foldable intraocular lens has an equilibrium water concentration of from about 1.5 wt % to about 10 wt % and a refractive index greater than about 1.50.
