  • Foldable intra-ocular lens
    Patent number: 6387127
    Abstract: An intraocular lens includes (1) a foldable optical lens part made of a copolymer; and (2) a harder haptic part. A high crosslinking of the copolymer of the lens part and of the haptic part results in a high stability against hydrolysis in a biological medium.

    Inventor: Wolfgang Müller-Lierheim
  • Contact lens
    Patent number: 5069542
    Abstract: A contact lens has an elliptical inside surface with a numerical eccentricity of 0.2 to 0.5 and a zenith radius of curvature of 8.0 to 8.4 mm. The inside surface preferably has a peripheral, circularly cross sectioned bevelled zone. As a soft contact lens, it has these dimensions when fully hydrated and preferably consists of a copolymer comprising of 50% to 90% hydroxyethyl-methacrylate (HEMA) by weight, 2% to 20% one or more unsaturated carboxylic acids, 2% to 20% one or more base monomers, 5% to 25% aliphatic acrylate or methacrylate, and 0.1% to 1% of a dialkylene-glycol-dimethacrylate cross-linker.
    Type: Grant
    Filed: April 21, 1988
    Date of Patent: December 3, 1991
    Assignee: Titmus Eurocon Kontaktlinsen GmbH & Co. KG.

  • Contact lens having improved eye compatibility
    Patent number: 4895896
    Abstract: Contact lens comprising an eye-compatible surface on which monoclonal antibodies or fragments of antibodies are immobilized, the N-terminal ends of which are directed against mucous substances of the human ocular tear film.
    Type: Grant
    Filed: August 14, 1987
    Date of Patent: January 23, 1990
    Inventor: Wolfgang Muller-Lierheim
  • Contact lens and compositions
    Patent number: 4463148
    Abstract: A soft contact lens having in preferred embodiment an elliptical inside surface which has a numerical eccentricity of 0.2 to 0.5 and a zenith radium of curvature of 8.0 to 8.4 mm. It preferably consists of a copolymer comprising of 50% to 90% hydroxyethyl-methacrylate (HEMA) by weight, 2% to 20% one or more unsaturated carboxylic acids, 2% to 20% one or more base monomers, 5% to 25% aliphatic acrylate or methacrylate, and 0.1% to 1% of a dialkylene-glycol-dimethacrylate crosslinker.
