20160067035 | Intraocular Lens With Central Hole For Improved Fluid Flow And Minimized Light Scattering - 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. | 03-10-2016 |
20140316425 | INJECTOR CARTRIDGE WITH IMPROVED LUBRICITY - 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 (T | 10-23-2014 |
20140316424 | PRE-LOADED INJECTOR FOR USE WITH INTRAOCULAR LENS - An injector folding and injecting a flexible intraocular lens into the eye of a patient is described. The injector is configured to be loaded with the intraocular lens, and optionally, an aqueous solution, before the injector and lens are sterilized. The injector includes a lens compartment that is configured to prevent leakage of the aqueous fluid from the lens compartment caused by autoclaving/sterilization. | 10-23-2014 |
20140135919 | FREE-FORM PROGRESSIVE MULTIFOCAL REFRACTIVE LENS FOR CATARACT AND REFRACTIVE SURGERY - 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. | 05-15-2014 |
20100228261 | DISPOSABLE INTRAOCULAR LENS INSERTION SYSTEM - An intraocular lens injection system comprising an injecting device and cartridge. The cartridge comprises a lens holding portion and an outer sleeve portion. The invention includes a method of pre-loading the injecting system, particularly the cartridge, to reduce the amount of packaging, prevent damage to the intraocular lens during packaging and shipping, allow the pre-loaded injecting cartridge to be autoclaved as a unit, and eliminate the step of loading the cartridge with the intraocular lens by the end user to prevent potential damage during this step. | 09-09-2010 |
20090292354 | OPTIMIZED INTRAOCULAR LENS - 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. | 11-26-2009 |
