Abstract: An intraocular lens having a lens base and a coating layer disposed on or otherwise operably associated with a first surface of the lens base. The coating layer is formed by, for example, plasma polymerization of a monomer gas while simultaneously sublimating or evaporating an ultraviolet absorber, thereby forming an intraocular lens which absorbs ultraviolet rays and prevents any free monomer or other substance from oozing out of the lens base and permeating the eye. The properties of the intraocular lens can be readily varied by selecting different monomer gases.
