Abstract: A method of generating three dimensional shapes for a cornea and lens of an eye, the method including illuminating an eye with multiple sections of light and obtaining multiple sectional images of said eye based on said multiple sections of light. For each one of the obtained multiple sectional images, the following processes are performed: a) automatically identifying arcs, in two-dimensional space, corresponding to anterior and posterior corneal and lens surfaces of the eye by image analysis and curve fitting of the one of the obtained multiple sectional images; and b) determining an intersection of lines ray traced back from the identified arcs in two-dimensional space with a known position of a section of space containing the section of light that generated the one of the obtained multiple sectional images, wherein the determined intersection defines a three-dimensional arc curve.

Abstract: An alignment device including means for releasably attaching a suction ring and means for applying a pattern of light to an eye of a patient. The alignment device further including means for detecting light reflected from the eye and determining whether the suction ring is aligned relative to the eye based on the detected light.
Abstract: There is provided a device for use as an interface between a laser surgery device and the eye of a patient. The device is filled with a liquid that matches the index of refraction of the eye. The device further has a curved lens that follows the curvature of the outer surface of the patient's eye. In this manner the interface device, through which the laser beam must travel, has essentially the same index of refraction as the eye.
