Abstract:
A method for treating the surface of a silicone medical device comprising the following steps:(a) subjecting the surface of the silicone medical device to a plasma-polymerization reaction in a hydrocarbon-containing atmosphere to form a polymeric carbonaceous layer on the surface of the silicone medical device having a thickness of 50 to 500 Angstroms; (b) forming reactive functionalities on the surface of the carbonaceous layer; and (c) exposing the surface of the silicone medical device to a solution of a hydrophilic reactive polymer having complementary reactive functionalities on the carbonaceous layer, thereby forming a biocompatible surface on the silicone medical device, wherein the silicone medical device is a silicone contact lens or silicone intraocular device.
