  • Publication number: 20120277342
    Abstract: Novel polymers for biomedical use, especially rigid gas permeable contact lenses that are based on bulky side-chain siloxane cross linkers. The siloxanes, either alone, or as copolymers with bulky and non-bulky mono-functional polymerizable siloxanes, fluoro monomers, such as hexafluoroisopropyl methacrylate, and hydrophilic monomers, result in transparent, high oxygen permeable polymers possessing excellent lathing and milling characteristics.
    Type: Application

  • Patent number: 7781496
    Abstract: An intraocular lens comprising a polymer that is prepared from a monomer mixture comprising a monomer of formula G-D-Ar??(I) wherein Ar is a C6-C24 aromatic group having a hydrophilic substituent, D is a divalent linking group, and G is a reactive functional group selected from the group consisting of acryloyl, acryloyloxy, methacryloyl, methacryloyloxy and mercapto. The polymer has an equilibrium water content of greater than 4.5 percent by weight.

  • Patent number: 7632904
    Abstract: Hydrophilic, arylsiloxy-containing monomers and macromonomers have at least a terminal hydrophilic group attached to an arylsiloxy group. The aryl groups attached to siloxy groups can be substituted with other hydrophilic groups. Polymers comprising such hydrophilic, arylsiloxy-containing monomers and macromonomers avoid or reduce the risk of forming vacuoles of absorbed water. Furthermore, such polymers have high refractive index, and, thus, are advantageously used for making ophthalmic devices, such as intraocular lenses, contact lenses, corneal rings, corneal inlays, and keratoprostheses.

  • Publication number: 20090168013
    Abstract: A method for reducing the modulus of polymer siloxane hydrogel compositions by employing monomeric polysiloxanes endcapped with trimethylsilyl to reduce the crosslinking density of the hydrogel. The synthesis consists of a single vessel acid catalyzed ring opening polymerization and may be employed to produce copolymers useful as hydrogel contact lens materials.
