It is an object of the invention to provide a surface-modified polymer that has improved biocompatibility and the method of making the same. It is particularly, an object of the invention to provide a surface modified poly (methyl methacrylate) intraocular lens that causes a reduction in adhesion damage of corneal endothelium cells during surgical implantation. It is an object of the invention to provide an improved, modified intraocular lens material, which includes a rigid, low-energy surface having reduced adhesion characteristics with corneal cells. The improved intraocular lens material of the invention is an intraocular lens material polymer substrate including a fluorocarbon polymer coating bound covalently to the ! substrate. The fluorinated coating will protect the lens from degradation by the body by virtue of the dense and impermeable cross-linked nature of the film coating. Also, the fluorinated film will protect leaching of fusible components from the lens into the body.
