  • Polymeric intraocular lens material having improved surface properties and intraocular lens construction
    Patent number: 6143027
    Abstract: An intraocular lens is described that includes an optic portion formed of an optically suitable polymer or glass material that has been coated by a fluorocarbon polymer. A haptic portion of the IOL is attached to the optic. The resulting low-energy IOL surface induces significantly reduced cell damage when contacted with corneal endothelial tissues. The fluorocarbon polymer coating is preferably applied by exposing IOL surfaces to a plasma formed from a gaseous fluorocarbon monomer. The resulting IOL causes substantially less damage to corneal endothelial cells during implantation.

  • Polymeric intraocular lens material having improved surface properties
    Patent number: 5091204
    Abstract: A method of making an improved intraocular lens for implanting in the eye by coating a glass or polymeric lens substrate with a fluorocarbon polymer to produce a rigid, low-energy surface that will significantly reduce adhesion and damage to corneal endothelial tissues upon implantation. The preferred lens material is produced by exposing the lens substrate to a gas plasma of a fluorocarbon monomer.
