  • 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.
    Type: Grant

  • Material for ocular prosthetics
    Patent number: 4647282
    Abstract: An optical prosthetic device made from a material based on silicone compounds is a cured composition resulting from vulcanization of a mixture of .alpha.,.omega.-bis-trivinylsiloxyoligodimethyl(methylphenyl)-siloxane and .alpha.,.omega.-bis-trimethyl(dimethylhydro)siloxyoligomethyl(phenyl)methy lhydro-siloxane in the presence of a polyaddition reaction catalyst based on the compounds of metals of the platinum group, the ratio of the first mixture component to the second one ranging within 100:1 and 100:20 parts by mass.
