  • Patent number: 9636216
    Abstract: An inorganic-organic hybrid coating applied to a polymer and method for forming same to provide improved hydrophilicity and lubricity to the surface of the polymer. The hydrophilic coating is on the order of one micron thick, as is formed by activating the surface of the polymer, reacting the activated surface of the polymer with a Lewis acid metallic composition, and then quenching the coating in salt solution having a pH>7.2 at a temperature above the glass transition temperature (Tg) of the polymer.

  • Publication number: 20160067035
    Abstract: An implantable contact lens having a central hole with angled walls optimized to minimize light scattering is described. The central hole provides fluid flow from the posterior to the anterior chamber of the eye, and its shape and size of designed to reduce glare and halos resulting from light scattered by the walls of the hole. The design parameters of the hole are dependent on the refractive index of the material in which the central hole is formed.

  • Publication number: 20140135919
    Abstract: A new type of multi-focal lens that has a free-form progressive multifocal front surface consisting of a 16th order polynomial superimposed on a standard conic base surface is described. The center region of the lens is optimized for distance vision, while simultaneously optimizing the rest of the lens for near vision. The resulting free-form even asphere polynomial surface is smooth, unlike present day diffractive multifocal designs. Additionally, this lens design is suitable for both refractive and cataract surgeries.

  • Publication number: 20090292354
    Abstract: An optimized aspheric lens has improved optics when implanted into a patient having a curved retina. Light entering the optimized aspheric lens on-axis or at an angle to the optical axis is properly focused by the lens, reducing aberrations and producing a much smaller spot size of light on the retina. A method of selecting the optimized values for variables of the lens design, such as base radii of the front and back surface of the lens, conic constants of the front and back surfaces, and/or center thickness of the lens, among other possible parameters is provided. The method includes calculating changes in a merit function while changing the various values for the variables and selecting an optimized merit function.

  • Publication number: 20070244560
    Abstract: The invention provides a medical device and method to reduce the occurrence of pseudophakic pupillary block following implantation of an intraocular lens. The device includes an intraocular lens configured with channels traversing through the surfaces of the lens optic. The invention includes special edge angulations and locations in the optic zone that eliminate optical distortion from channels. The channels perform as valves configured to allow flow of a patient's aqueous humor from one surface of the lens through to the other surface of the lens, thereby preventing fluid pressure from building up in a patient's eye.

  • Publication number: 20040087963
    Abstract: A cartridge having increased lubricity and a method used to increase the lubricity of medical devices such as a lens cartridge. The inner surface of a lens cartridge formed from polypropylene and at least one other constituent is exposed to a treatment gas, which may be a mixture of steam and carbon dioxide gas, humidified carbon dioxide, sulfur dioxide, nitrogen dioxide or a combination thereof, to increase the lubricity of an inner surface of the lens cartridge or medical device. Various processing conditions may be controlled to control the amount of increased lubricity.
