CA 2440356

A method and system (10) for laser surgery produces controlled laser pulses and simultaneously verifies that a correct sequence of pulses are being delivered to the patient (214). A photo detector (204) receives a predetermined portion of the energy of the treatment pulses as they exit the system (10). A separate monitoring computer (208) compares an output signal from the photo detector with reference information for the treatment sequence. The system is exemplified in an implementation in an ophthalmic laser surgery system (10).

L'invention porte sur un procédé et un système (10) de chirurgie au laser produisant des impulsions contrôlées tout en vérifiant que les suites d'impulsions requises sont fournies au patient (214). A cet effet un photodétecteur (204) reçoit une partie prédéterminée de l'énergie des impulsions de traitement sortant du système (10), puis un ordinateur (208) séparé de surveillance compare le signal de sortie du photodétecteur avec une information de référence sur la séquence de traitement. Le système (10) peut par exemple servir en ophtalmologie.
