Abstract

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.
