A device for optically examining and/or treating a patient's eye has a lighting and/or observation optical unit (3) that can be freely moved and oriented in the direction of all co-ordinates in space above the left or right eye (29) and has a flat area that can be set on the surface of the eye. The optical unit is preferably retained in the adjusted position relative to the eye so as to maintain itself in a fixed position in relation to the patient's head and to move together with the head, when the patient can move his head. The treating doctor thus does not need to carry out manual positioning and/or securing operations while diagnosing and/or treating the patient. On the contrary of known optical treatment devices, unwanted degrees of freedom of motion are excluded by the disclosed device, and the risk of injuries is considerably reduced. In particular, laser beams can be more safely used for treating the eye.

Ce dispositif d'examen optique et/ou de traitement de l'oeil d'un patient comprend une optique d'éclairage et/ou d'observation (3) qui peut se déplacer ou s'orienter librement dans la direction de toutes les coordonnées dans l'espace, au-dessus de l'oeil gauche ou droit (29), et qui comprend une zone plate qui peut être posée sur la surface de l'oeil. De préférence, l'unité optique est retenue dans la position ajustée par rapport à l'oeil de façon à se maintenir dans cette position fixe par rapport à la tête du patient et à se déplacer avec la tête lorsque le patient bouge la tête. Le médecin traitant n'a pas à effectuer des manipulations de positionnement et/ou de retenue pendant le diagnostic et/ou le traitement. Au contraire des dispositifs optiques connus de traitement, ce dispositif exclut tous degrés indésirables de liberté de mouvement et réduit considérablement le risque de lésions pendant son utilisation. Il permet notamment de traiter l'oeil avec des faisceaux laser avec une plus grande sécurité.
