SURFACE-TREATMENT OF SILICONE MEDICAL DEVICES COMPRISING AN INTERMEDIATE CARBON COATING AND GRAFT POLYMERIZATION

摘要

The present invention provides an optically clear, hydrophilic coating upon the surface of a silicone medical device by sequentially subjecting the surface of the lens to plasma polymerization reaction in a hydrocarbon atmosphere to form a carbon layer, and then graft polymerizing a mixture of monomers comprising hydrophilic monomers onto the carbon layer. The inventio n is especially useful for forming a biocompatible coating on silicone hydroge l contact lenses.
