Soft corneal contact lens with tightly cross-linked polymer coating and method of making same

摘要: A soft corneal contact lens comprising a soft, highly oxygen-permeable, polymeric having formed on the surface thereof an ultrathin, optically clear, impermeable barrier coating. The coating is tightly cross-linked and comprises reaction product resulting from electrical glow discharge polymerization process conducted in gaseous atmosphere will prevent diffusion into of lipids other large molecules eye's tear film. silicone or polyurethane. consists essentially compounds selected group consisting hydrocarbons; halogenated hydrocarbons hydrogen; halogen; mixture any two more these compounds. fully hydrophilic which accomplished during additional step presence oxygen argon.
