  • 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.
