DEVICES AND METHODS FOR IMPROVING VISION

摘要

Corneal onlays and corneal onlay production methods are described. The present corneal onlays include a lens body. An example of a corneal onlay includes a lens body that includes a corneal epithelium-contactable anterior surface and a Bowman's membrane-contactable posterior surface. The lens body has an optical power from about -10 diopters to about +10 diopters, an optic zone diameter from about 5 mm to about 11 mm, a base curve from about 5 mm to about 12 mm, a center thickness from about 10 micrometers to about 300 micrometers, and an edge thickness from about 0 micrometers to about 120 micrometers. Methods include forming the present corneal onlays from polymeric materials.
