  • High refractive index silicone for use in intraocular lenses
    Patent number: 6432137
    Abstract: An intraocular lens made from a class of optically clear, ultraviolet (UV) light absorbing, vulcanized silicone compositions containing about 35 mole % or greater phenyl groups (C6H5), suitable for implanting in the human eye is disclosed. The high mole percentage of phenyl groups in the vulcanized silicone compositions provides a high refractive index (at least about 1.50) and partially blocks ultraviolet light absorption.
