ABSTRACT:
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 in a hydrocarbon-containing atmosphere and then covalently attaching a preformed hydrophilic polymer to the surface of the carbon coating. The invention is especially useful for forming a biocompatible coating on a silicone contact lens.
