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.
