  • Surface-modified self-passivating intraocular lenses
    Patent number: 5171267
    Abstract: The invention relates to intraocular lenses coated with C.sub.12 -C.sub.36 alkyl groups that render the surface of the intraocular lens less prone to causing inflammation after implantation of the intraocular lens. The alkyl groups may be coated on the IOL by a centrifugal casting method, a solution deposition method (e.g., a covalent attachment method), or a plasma deposition method that minimizes fragmentation of the alkyl groups.
