This invention is an accurate, non- mechanical removal of the epithelium (16) from essentially only the area of the cornea to be treated. In particular, an epithelium ablative laser device irradi- ates the selected region of the epithelium with ablative laser energy (21), a spectro- scopic system nonitors (90) the ablation and spectroscopically determines whether epithelium is being ablated, and a control system (50) terminates the epithelium re- moval upon spectroscopic determination of a substantial absence of epithelium ab- lation.
