Patent ID: 10143589

Abstract:
A method and apparatus for making improved surgical incisions in corrective eye surgery are provided. It was observed that a uniform elongated AK (or LRI) incision provides a non-uniform corrective effect due to non-uniform post-surgical relaxation of ophthalmic tissue. The method and apparatus leverage this observation to provide for creation of a surgical incision that is structured to be non-uniform along its length in such a manner as to at least partially counteract an expected variation in ophthalmic tissue relaxation to provide overall increased uniformity of corrective effect. An automated laser surgery system includes a laser control system configured to control laser delivery to cause selective ablation of ophthalmic tissue to provide an elongated structured incision that varies along its length in at least one of a depth, a profile, a width, and an angle of attack relative to a surface of the ophthalmic tissue.
