  • Foldable ophthalmic and otorhinolaryngological device materials
    Patent number: 6653422
    Abstract: Disclosed are soft, high refractive index, acrylic materials having an elongation of at least 150%. These materials, especially useful as intraocular lens materials, contain an aryl acrylic hydrophobic monomer as the single principal device-forming monomer. 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 prepared using a post-polymerization cross-linking method
    Patent number: 6313187
    Abstract: Acrylic, high refractive index ophthalmic device materials comprising an aryl acrylic monomer, a first stage polymerization initiator and a second stage cross-linking agent are prepared in a two-stage method. The monomers used to form the ophthalmic device materials do not contain cross-linking agents having more than one unsaturated bond. In the first stage of the method, the materials are polymerized. In the second stage, the materials are cross-linked by exposure to heat.
