<p>An apparatus and a method for removing epithelium from the cornea include a fluid agent for facilitating de-epithelialization of the cornea. A disc includes a biocompatible material operable for covering a predetermined zone of a cornea. The disc is hydrated by the fluid agent, wherein the hydrated disc is pliable for conforming to a surface of the cornea. An application of the hydrated disc to the cornea substantially constrains the fluid agent to the determined zone and softens a corneal epithelium enabling de lamination of the epithelium from an underlying stroma.</p> |
