ABSTRACT:
Corneal tissue and, in particular, Bowman's membrane is removed by abrading an annular zone of the cornea. The corneal tissue is abraded by rotating an abrading tool having an annular abrading surface in contact with the cornea. A corneal onlay can be attached to the abraded zone of the cornea.
