U 279 INSERM, Lille.


This article presents a system of oculomotor control of the microscope used in ophthalmic microsurgery. An eye movement sensor has been integrated within the microscope lens. The information provided by this sensor is used to control the position of the microscope with no alteration of the surgeon's visual functions and no interference with his visual sensori-motor reflexes. Results have been obtained from laboratory experimentations as well as from a series of anterior and posterior segment surgical procedures. They demonstrate the high precision and sensitivity of the gaze control which can be used to compensate for the reduction of the field of vision resulting from the optical magnification of the microscope.
