| 摘要 |
This invention is an accurate, nonmechanical removal of the epithelium (16) 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 (21), a spectroscopic system nonitors (90) the ablation and spectroscopically determines whether epithelium is being ablated, and a control system (50) terminates the epithelium removal upon spectroscopic determination of a substantial absence of epithelium ablation.
