Method for producing an intraocular lens

摘要

An intraocular lens of one-piece body consisting of supporting portions 34 and an optical portion 32 is formed by forming an annular supporting-portion-forming blank 2 composed of a polymerization product for supporting portion 34, which has a thickness to form the supporting portion 34 for an intraocular lens and has a through hole 4 formed by concentrically drilling the central portion on the basis of the outer diameter of the blank; forming a composite-lens-forming blank 24 by filling in the through hole a monomer composition 16 for forming another polymerization product 22 for the optical portion followed by polymerizing it whereby the polymerization product 22 is formed integrally in the through hole; and processing the blank 24 on the basis of its outer diameter.
