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.
L'invention concerne une excision non mécanique et précise de l'épithélium (16) exclusivement de la zone de la cornée à traiter. Plus particulièrement, un dispositif à laser d'ablation de l'épithélium irradie d'énergie laser (21) la région sélectionnée de l'épithélium, un système spectroscopique contrôle (90) l'ablation et détermine par spectroscopie si ce dernier est en cours d'excision, et un système de commande (50) achève l'excision de l'épithélium en déterminant par spectroscopie l'absence ou non d'ablation d'épithélium.
