INTRAOCULAR LENSES AND PROCESS FOR PRODUCING MOLDED-IN TYPE INTRAOCULAR LENSES

摘要

Molded-in type intraocular lenses consisting of an optical member and support members, wherein the optical member is made of a copolymer prepared by polymerizing 2-¢2-(perfluorooctyl)ethoxy!-1-methylethyl (meth)acrylate, an alkyl (meth)acrylate and a cross-linkable monomer at a given ratio and each support member is made of polymethyl methacrylate; a process for producing the same; and soft intraocular lenses consisting of an optical member and support members each made of a soft material, wherein each support member is provided with a flexible part having a specified function. The molded-in type intraocular lenses can be inserted into eyes via a small incised wound while flexing the optical member. After being inserted into eyes, the soft intraocular lenses can prevent the soft optical member from being deformed by the capsular constriction.
