ABSTRACT:
A method of producing an intraocular lens including a lens body, and at least one support member each of which is inserted into a mounting hole open in a circumferential surface of the lens body, the lens body being obtained by polymerization of a monomer composition in a mold assembly which defines a mold cavity having a profile following that of the lens body, the method comprising the steps of: installing a separately prepared insert member on the mold assembly such that the insert member is located within the mold assembly at a position of the mold cavity corresponding to a region of the lens body where the mounting hole is formed; polymerizing the monomer composition in the mold assembly to provide a workpiece which gives the lens body, such that the workpiece includes the insert member; obtaining the lens body from the workpiece such that at least a portion of the insert member is embedded as an insert in the region of the lens body; and forming the mounting hole in the insert.
