ABSTRACT:
Accurate, non-mechanical removal of the epithelium from essentially only the area of the cornea to be treated. In particular, an epithelium-ablative laser device irradiates the selected region of the epithelium with ablative laser energy, a spectroscopic system monitors the ablation and spectroscopically determines whether epithelium is being ablated, and a control system terminates the epithelium removal upon spectroscopic determination of a substantial absence of epithelium ablation.
