  • COMPOSITIONS WITH HIGH REFRACTIVE INDEX AND ABBE NUMBER
    Publication number: 20260028439
    Abstract: Disclosed are co-polymers which are produced from reactive monomer mixtures and which have both high refractive index and a high Abbe number. These materials are well suited for use as implantable ophthalmic devices and have a refractive index which may be edited through application of energy. When used for an intraocular lens, the high refractive index allows for a thin lens which compresses to allow a small incision size.
    Type: Application

  • HIGH REFRACTIVE INDEX, HIGH ABBE COMPOSITIONS
    Publication number: 20240384021
    Abstract: Disclosed are hydrophobic, acrylic materials having both high refractive index and a high Abbe number. The materials may have an internal wetting agent, are well suited for use as implantable ophthalmic devices, and have a refractive index which may be edited through application of energy. When used for an intraocular lens, the high refractive index allows for a thin lens which compresses to allow a small incision size.

  • Magnetic knife guard device
    Patent number: 8276768
    Abstract: A magnetic knife guard that attaches to one side of a knife and enables a user to safely and easily store individual knives in a drawer or hang individual knives on kitchen utensil racks without damaging or dulling the cutting surface of the knife. An embedded magnet within the guard holds the guard to the blade while a plurality frictional contact pads prevent slipping or rotation of the guard on the blade.
