Method of correcting vision using corneal onlays

摘要

A corneal onlay is configured to adhere to the cornea so as to inhibit epithelial growth under the onlay. Structures can be provided on the onlay to adhere the onlay to the eye. At least one of an epithelial layer or the water inhibiting layer can be provided on or over the onlay, for example a natural epithelial layer or water inhibiting layer that inhibits, for example minimizes, water penetration into the onlay, so as to adhere the onlay to the eye with pumping of the endothelium. The water inhibiting layer may comprise a therapeutic covering positioned over the onlay to inhibit swelling of the cornea. The posterior surface of the onlay may be shaped so as to fit the anterior exposed surface of the cornea.

主权项

1. A method of correcting vision comprising:
(a) obtaining an onlay configured to correct vision of an eye of a human and a separate therapeutic covering; (b) placing the onlay on the cornea of an eye of a patient so as to correct vision of the eye; and subsequently (c) placing the covering on the cornea so that it covers and extends around the onlay, thereby promoting regeneration of epithelium between the covering and the onlay; wherein the therapeutic covering is a solid covering device that comprises a water inhibiting layer, thereby configuring the covering to adhere to the cornea by endothelial cell suction.
