Abstract

A method and apparatus for providing more precise aiming by an eye tracking system, including a registration or aiming laser, that provides for precise location of where the next laser ablation shot will impinge upon the eye. The method and apparatus further includes an aiming assistance fixture that provides a fixed frame of reference for locating the origin of the eye.
