  • Manufacture of ophthalmic lenses
    Patent number: 10336022
    Abstract: A method of manufacturing an ophthalmic lens using a first mold portion and a puck assembly. The puck assembly comprises a carrier puck. The puck assembly supports at least one of the first mold portion and the lens during at least two of the following ophthalmic lens manufacturing steps: assembling the first mold portion and a second mold portion into a mold assembly including a lens-defining cavity containing a lens precursor material; curing the lens precursor material in the mold assembly to form a lens; separating the mold assembly such that the lens remains attached to the first mold portion; detaching the lens from the first mold portion; extracting unwanted material from the lens; hydrating the lens; inspecting the lens, and packaging the lens.

  • Methods of Manufacturing Coated Contact Lenses
    Publication number: 20190129202
    Abstract: Methods are disclosed for manufacturing a coated contact lens that comprises a polymeric lens body comprising an acid group, a first coating polymer comprising a first amine group ionically bound to the acid group, and a second coating bound to the first coating polymer through covalent linkage between a nitrogen atom of a second amine group on the first coating polymer and an amine-reactive group of the second coating polymer. In some examples the lenses exhibit improved surface properties compared to uncoated lenses, such as reduced adhesion, increased wettability, increased lubricity, and/or increased lipid resistance.

  • COMPLEX CATALOG MATCH SYSTEM
    Publication number: 20190129987
    Abstract: Systems and techniques are provided for a data matching system having a plurality of clients and a master catalog. In a learning phase of a client, the data matching system builds a client matching table for the client and matches the input request to a specific entry in a particular set of entries in the master catalog. In a post-learning phase of the client, the data matching system uses the client matching table to match the input request to a specific entry in a particular set of entries in the master catalog. In a specific implementation, the data matching system uses a two-step match to build the client matching table. In a first step, a plurality of a set of entries in the master catalog is selected for the input request. In a second step, a particular set of entries is selected using a confidence score.

  • Methods and systems for replenishing supplies in a product array
    Patent number: 10249388
    Abstract: The present disclosure provides systems and methods to aid in the resupply of product arrays, such as contact lenses. In an aspect, this is accomplished by providing a physical product array to a reseller. Additionally, a computer-operated application is provided that displays a virtual representation of the physical product array. The reseller can then manipulate the virtual storage array to more easily identify the specific product slots in the array that need to be restocked, and the application can interact directly with an ordering system for the product manufacturer to submit orders for fulfillment. In an aspect, the application stores the product attributes for each slot of the product array, so that a simple visual inspection of the physical array can be translated into the proper product without a reseller having to determine product attributes for the specific array slots.

  • Method of Manufacturing Coated Silicone Hydrogel Contact Lenses
    Publication number: 20180354213
    Abstract: Contact lenses having even surface coatings are manufactured by coating a polyvinyl alcohol polymer on a lens-forming surface of a contact lens mold, applying a contact lens coating composition onto the polyvinyl alcohol polymer, and curing a contact lens formulation in the coated contact lens mold. During curing, the coating composition transfers from the mold to the contact lens surface. The polyvinyl alcohol helps prevent the contact lens coating composition from being solubilized by the contact lens composition during the curing step.

  • Method and apparatus for manufacturing contact lenses
    Patent number: 10029402
    Abstract: Apparatus and methods are described for manufacturing contact lenses by forming a contact lens mold half, and removing the mold half. The mold half can then be combined with a complementary mold half and used to cast-mold a contact lens. The apparatus includes first and second plates each carrying tool halves. The plates reciprocate between an open, spaced apart configuration, and a closed configuration in which they hold complementary tool halves in contact with one another. When the plates are opened after forming a mold half, a gripper plate removes the mold half from the first plate or the second plate.
