  • Patent number: 8455572
    Abstract: This invention relates to the fields of polymer chemistry, materials science and ophthalmology. More particularly it relates to optical components and method(s) of preparing same from hydrophobic acrylic (HA) monomer(s) that exhibit reduced or eliminated glistenings when implanted in a patient's eye. The method of this invention uses a mixture of one or more low temperature initiators (LTI) combined with one or more high temperature initiators (HTI), to polymerize one or more HA monomers to produce an optical HA polymer which, when used to manufacture an optical component and implanted as with an intraocular lens (IOL), exhibit reduced glistenings to the patient.

  • Patent number: 8247511
    Abstract: The current invention provides a method of forming a foldable intraocular having a high refractive index from a copolymer comprising a first monomer comprising an aryl acrylate or an aryl methacrylate; a second monomer comprising an aromatic ring comprising a substituent having one ethylenic unsaturation, provided that the second monomer is not an aryl acryate or aryl methacrylate, and a third monomer comprising one ethylenic unsaturation that, if polymerized into a homopolymer, forms a high water content hydrogel; and, optionally, a cross-linking agent.

  • Publication number: 20120150292
    Abstract: This invention relates to intraocular lenses. More particularly, this invention relates to intraocular lenses that have the ability to alter the light refractive power in response to changes in the tension of the ciliary muscle or ciliary body of the eye or any other accommodative forces. Lenses of this invention are generally referred to as interfacial, i.e., lens properties being defined as the interface of two liquids having different refractive indices, refractive accommodating lenses (IRAL).

  • Patent number: 7857848
    Abstract: Infinite gradient refractive index ophthalmic devices and methods of making same. The method involves diffusing a monomer which polymerizes to a lower or higher corresponding opposite refractive index polymer into a lower or higher index polymer structure and polymerizing same to create the gradient structure. The resulting polymeric structure is used to manufacture ophthalmic devices, e.g., intraocular lenses.
