摘要

A piece of apparatus for measuring the topography and thickness of the cornea and a measuring method employed to this end, this piece of apparatus comprising a system for tracking (1) the direction of gaze (D) of the eyes (2), which includes a camera (6) and a diffuse light emitter (7) for each eye (2); a system for inspecting (3) the cornea (4), which comprises a light emitter (8) for each eye (2) and emits light beams (9) onto the cornea (4) and a receiver assembly (10), which receives the light reflected by the cornea (4); a system for displaying visual stimuli (13) in front of the eyes (2) and; a computer (5) that controls the light emitters (7, 8) and the system for displaying visual stimuli (13), which also processes the information from each camera (6) and the receiver assembly (10), in order to determine the topography and thickness of the cornea (4) of each eye (2).
