James Lisk - Suwanee GA, US
Scott Hampton - Cumming GA, US

International Classification:

A61F009/00

US Classification:

606/166000

Abstract:

A separator constructed of a polymeric material is used with a surgical device that separates the epithelium of a cornea from the underlying Bowman's layer of an eye of a patient. The surgical device includes a positioning ring for temporary attachment to the eye and is structured to present and expose the cornea to be separated. The separator support is structured and disposed to carry the separator. A drive is operably connected to the separator support for causing movement of the separator across the positioning ring and for causing oscillating movement of said separator.

Abstract:

An instrument for separating at least a portion of the epithelium from Bowman's layer of a cornea of an eye. The instrument includes a vacuum-operated positioning ring for temporary attachment to the eye so that the cornea is received and exposed in a non-planar configuration and the epithelium is not in contact with any portion of the instrument. In addition, the instrument has a separator with an edge that separates the epithelium of the non-planar cornea from the underlying Bowman's layer as the separator moves along a predetermined path intersecting the cornea. No portion of the instrument contacts the epithelium prior to it being separated from Bowman's layer by the separating edge.
