Abstract
An ophthalmic surgery system (10) for performing corneal keratotomies and resectomies utilizes a light source (12) which generates a pulsed beam in the ultraviolet/vacuum ultraviolet region. The beam is received by a sealed base unit (16) and attached rotatable subunit (18) which shape, focus, and project the beam onto a protective mask (20) mounted directly on the eye (22) of a patient. The mask (20) includes a normally closed shutter (148) which opens responsive to a counter (32) positioned along the beam path and sensors (156) positioned on opposite sides of a control slit (154) to apply a predetermined number of pulses while the mask is aligned to effect precise cutting of the cornea to the desired depth.
