  • Method and system for removing an epithelial layer from a cornea
    Patent number: 6068625
    Abstract: Laser ablative radiation is used to remove the epithelial layer from over the stromal layer in a cornea. While uniform exposure of a single or scanned ablative beam will generally remove peripheral portions of the epithelial layer faster than central portions, such non-uniform removal is corrected by patterning the beam to reduce peripheral exposure relative to central exposure.
