Patent ID: 7083645

Claim:
A method of manufacturing an intraocular lens, the method comprising: a) a first monomeric component which comprises an aryl acrylate or an aryl methacrylate; a second monomeric component which comprises a monomer having an aromatic ring with a substituent having at least one site of ethylenic unsaturation, wherein the second monomeric component is other than an acrylate; and, a third monomeric component which comprises a high water content hydrogel-forming monomer, wherein: the copolymer has a glass transition temperature greater than about normal room temperature; b) forming a rigid intraocular lens having the desired dimensions from the copolymer; and c) hydrating the copolymer to from a foldable, hydrated intraocular lens; wherein: hydrating the copolymer comprises placing the copolymer in an aqueous solution; gradually increasing the temperature of the aqueous solution to about 40° C., holding the temperature of the aqueous solution at about 40° C. for at least about 10 minutes; gradually increasing the temperature of the aqueous solution to about 60° C.; holding the temperature of the aqueous solution at about 60° C. for at least about an hour; and, gradually decreasing the temperature of the aqueous solution to about room temperature.
