  • Method of producing a keratoprosthesis
    Patent number: 5458819
    Abstract: A composite device which may be implanted in the cornea of the human eye to replace damaged or diseased portions, and a method of manufacturing the said device, are disclosed. The device consists of a transparent central portion intimately attached to an opaque spongy rim. Both portions are made of hydrogel materials produced in different conditions of polymerization during a two-stage process performed in a specific moulding unit. The spongy rim promotes and maintains cellular invasion from the host corneal tissue, thus providing a tight union between implant and recipient cornea which prevents the postoperative extrusion of the implant.
    Type: Grant
    Filed: December 20, 1993

    Assignee: Lions Eye Institute of Western Australia, Incorporated
