Method and apparatus for precision laser surgery

摘要: An eye laser system which includes a and delivery for delivering beam generated by the to eyetracking monitors movement of conveys information with including non-invasive tilt reference marker. The marker projects an energy tha is preferably visible so as reflect off iris provide microscope surgical field illumination. plurality points arranged concentrically about pupil and/or concentric ring marking device. This arrangement provides use in, example, video frame review during initial setting or subsequent tracking stage. Also descrived are systems accomodation that well suited described above indication data sufficient determining angle hence required accomodating aser coincident axis tilted eye.
