    摘要: The invention is related to a method for producing silicone hydrogel contact lenses with a stable lubricious hydrogel coating thereon. A method of the invention comprises forming a plasma-reactive hydrophilic polymer hybrid base coating having reactive functional groups on a silicone hydrogel contact lens and heating the silicone hydrogel contact lens with the hybrid base coating in an aqueous solution of a water-soluble and thermally crosslinkable hydrophilic polymeric material to form a stable lubricious hydrogel coating thereon.

    摘要: Described herein are methods for increasing the ion permeability of a silicone hydrogel contact lens by adding a small amount of an ion-permeability-enhancing ("IP-enhancing") hydrophilic vinylic monomer or macromer into a lens-forming material for cast-molding silicone hydrogel contact lenses, while not altering significantly the water content and/or the oxygen permeability of resultant lenses from the lens-forming material.
