HYBRID EYE TRACKING SYSTEM AND ASSOCIATED METHODS

摘要

A system (10) and method for tracking ocular changes (12, 13) during a surgical procedure include directing an eye-safe optical beam (21) toward an undilated, unparalyzed eye (90). A reflected optical beam (23) is detected (22), and measurements (17) are performed based upon data contained in the reflected optical beam of at least one geometric parameter of the eye at a predetermined frequency (105), and from them is calculated a change in the a t least one geometric parameter (106). The calculated change is used to dynamically adjust the directing of laser beam shots (14) during the surgery .
