  • Polymeric composition for ocular devices
    Patent number: 9622853
    Abstract: Polymeric and co-polymeric compositions useful for preparing ophthalmic and ocular devices, such as implantable intraocular lenses (IOL) and contact lenses, and processes of forming the compositions and devices are provided. The disclosed polymeric or co-polymeric composition may include a curcuminoid compound as a UV-blocker, and is derived from a pre-polymerization mixture of monomers which comprises at least 50 weight percents acrylate monomers and exhibiting visible light transparency and ultraviolet light opacity. The disclosed co-polymeric composition may alternatively, or in addition, be derived from a pre-polymerization mixture of defined monomers.
    Type: Grant
    Filed: July 5, 2011
    Date of Patent: April 18, 2017

  • Refractive-diffractive ophthalmic device and compositions useful for producing same
    Patent number: 9310624
    Abstract: A multifocal ophthalmic device is disclosed, wherein the lens body comprises a curcuminoid compound as a UV-light stabilizer, and/or a co-polymeric composition which is derived from a pre-polymerization mixture of defined monomers. The lens body of the multifocal ophthalmic device is being formed with a plurality of concentric annular zones, which effect both diffraction and refraction of incident light, and which are separated by slanted steps that are substantially devoid of any diffractive or refractive power.
