Abstract

L'invention concerne un microscope chirurgical destiné notamment à la chirurgie ophtalmologique. Il comporte un microscope binoculaire et une source lumineuse circulaire dont l'image est réfléchie par la cornée de l'oeil. Cette image est réfléchie par des prismes disposés à l'intérieur du microscope, formant ainsi plusieurs images dans une configuration déterminée avant l'opération. Pendant la suture d'une mcision faite dans la cornée, le chirurgien serre et desserre les points pour rétablir la même configuration d'image qu'avant l'opération, rétablissant ainsi le rayon de courbure initial de la cornée. L'invention s'applique notamment à l'opération de la cataracte
