ABSTRACT:
A trephine device for at least partially removing a section of the anterior epithelial cells from a corneal surface, typically prior to laser excimer reshaping of a portion of the corneal surface, comprises a housing having upper and lower end portions, removal apparatus integral to the housing, and apparatus for activating and deactivating the removal apparatus. The removal apparatus may have at least one cutting surface adapted to conform substantially to the shape of the cornea, with the cutting surface contacted with the cornea at a pressure sufficient to remove the anterior epithelial cells without affecting underlying corneal tissue.
