Abstract
A method used in a corneal lenticule procedure for finding the visual axis location before eye docking, to track the visual axis location displacement during docking, and to center the lenticule incision pattern at the visual axis location after docking, without ink-marking the visual axis location at the center of the cornea with ink or other substance. Two docking illumination beams are illuminated on the eye surface at oblique angles, and a first eye image is taken before docking while the eye looks at the fixation light of the laser system. A second eye image is taken after docking. The pre-docking cornea apex position is obtained based on the two reflected light spots of the docking illumination light. Pupil center is obtained in both images. The post-docking corneal apex is then calculated from the pre-docking cornea apex position and the pre- and post-docking pupil center positions.
