  • Patent number: 5310571
    Abstract: A method for treating hydrophilic and rigid gas permeable contact lenses, as well as the manufacture of protein adhesion resistant and gas permeable enhanced lenses, is obtained through purging the hydrated contact lens, formed from polymer comprising hydrogen atoms, substantially all water and oxygen, and thereafter exposing the purged contact lens to a fluorine-containing gas in non-plasma conditions for a period of time and at a temperature sufficient to replace hydrogen atoms in the polymer in order to inhibit protein deposits on the contact lens. The conditions of fluorine exposure can be controlled in order to provide a gas permeable enhanced contact lens.

  • Patent number: 5303023
    Abstract: An apparatus for inspecting a test lens, such as an intraocular lens, comprising a light source and collimating lens positioned to receive light from the light source and direct collimated light to the test lens. A plurality of targets are positionable at the object focal plane of the collimating lens so that there is an image of the target at the image focal space of the test lens. The image of the target has generally radially extending and alternating first and second sectors with each of the first sectors being relatively light and each of the second sectors being relatively dark. Modulation transfer function is determined by determining the image contrast along a combination of selected ring-shaped regions of the image.

  • Patent number: 5300114
    Abstract: A system for providing controlled release of an active agent in an eye includes a device with a shape thereof for enabling placement of the device under a conjunctiva of an eye and additionally preventing migration of the device in the eye after placement of the device under the conjunctiva. The device may be formed of a material permeable to the passage of an agent disposed in said device. In addition, a tracer may be incorporated in the device to enable visual indication of the amount of active agent in said device when said device is disposed under the conjunctiva. To selectively treat specific areas of the eye, an impermeable layer may be provided for preventing diffusion of the active agent from a selected area of the device.

  • Patent number: 5300262
    Abstract: The process of reproducibly making a wholly spuncasted, non-truncated, ballasted soft contact lens containing a compound anterior surface. The process comprises spincasting a polymer-forming, lens forming monomeric mixture in a cavity mold having a surface that is offset to allow for generation of a prismatic ballast, a compound curvature and a central axis that is symmetrical to the peripheral edge of the lens being formed. This is done by rotating the monomer mixture in the mold whereby the mixture replicates the mold's surface while at the same time undergoes polymerization and forms a prismatic lens with the central axis of its posterior surface symmetrical to its peripheral edge, a corneal bowl free of the compound curvature and possessing a thickness profile that is asymmetrical with respect to its geometric center.
