  • Low-tack ophthalmic and otorhinolaryngological device materials
    Patent number: 8058323
    Abstract: Disclosed are soft, high refractive index, acrylic materials. These materials, especially useful as intraocular lens materials, contain one or more aryl acrylic hydrophobic monomers as principal device-forming monomers and a tack-reducing macromer additive. In addition to their use as intraocular lens materials, the present materials are also suitable for use in other ophthalmic or otorhinolaryngological devices, such as contact lenses, keratoprostheses, corneal inlays or rings; otological ventilation tubes and nasal implants.

  • High refractive index ophthalmic device materials
    Patent number: 7790825
    Abstract: High refractive index copolymers suitable for use in ophthalmic devices are disclosed. The copolymers comprise a single aryl hydrophobic monomer as a device forming monomer. In addition, the copolymers comprise a non-polymerizable block copolymer surfactant. The copolymers have a reduced tendency to form glistenings when stored in water at physiological temperatures.

  • HYDROGEL INTRAOCULAR LENS AND METHOD OF FORMING SAME
    Publication number: 20090248150
    Abstract: The present invention is directed ophthalmic device materials and, more particularly to an intraocular lens (IOL) formed of a hydrogel material. The hydrogel material includes an acrylate polymer and a radiation resistant compound. The material typically has a relatively high refractive index and/or exhibits a desired degree of radiation protection.
