Method for producing contact lenses with wearing comfort

Abstract:

The invention is related to a method for producing silicone hydrogel contact lenses with a stable lubricious hydrogel coating thereon providing a low surface friction. 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.
