Abstract
The invention relates to a system for laser photocoagulation of the retina, comprising: a photocoagulation laser (1); an optical path (5) connecting the upstream photocoagulation laser (1) to a downstream laser outlet opening (6) intended to be positioned in front of the retina; an adaptive optical element (9) positioned in the optical path and configured to modify the wavefront of the laser beam being propagated in the optical path, in order to compensate for aberrations of the eye that occur as far as the retina; a position control loop (10) controlling a first actuator (14) positioned in the optical path downstream of the adaptive optical element in order to control the position of the laser outlet opening relative to the retina to be treated; and at least one imaging device (8) configured to obtain an image of the retina diverted from the optical path.
