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