Abstract

A method of manufacturing an intraocular lens includes: a first step of producing a base material for the intraocular lens by polymerizing a first polymerizable monomer which is a raw material of the base material; a second step of producing a monomer-impregnated base material by impregnating the base material produced in the first step with a second polymerizable monomer; a third step of setting a protective member on a surface of the base material produced in the second step to prevent the surface of the base material from drying; and a fourth step of polymerizing the second polymerizable monomer impregnated in the base material on which the protective member is set.
