Abstract:
1. A method of manufacturing an intraocular lens of a soft type which is foldable, including: a first step of making a first monomer mixed solution with plural monomers and polymerizing the plural monomers to produce a base material for the intraocular lens; a second step of heating the base material produced in the first step in an oven to terminate polymerization; a third step, after the second step, of immersing the base material into a second monomer mixed solution which is the same as the first monomer mixed solution to impregnate the base material with the second monomer mixed solution so that any voids formed in the base material can be filled; a fourth step, after the third step, of taking out the base material from the second monomer mixed solution and removing the second monomer mixed solution from a surface of the base material; a fifth step, after the fourth step, of heating the base material in an oven to cause repolymerization; and a sixth step, after the fifth step, of forming the intraocular lens from the repolymerized material.
