Corneal topography measurement and fiducial mark incision in laser surgery

摘要

A method of cataract surgery for a patient's eye includes the steps of identifying one feature selected from the group consisting of an eye axis, meridians and structures by corneal topography, and outside the optical region of the eye, the corneal axis. Forming a fiducial mark incision with a laser beam along a meridian or structure. The laser cataract surgery system includes a laser source, a topography measurement system, an integrated optical subsystem, and a processor in operative communication with the laser source, the topography measurement system, and the integrated optical subsystem. ing. The processor determines one of the patient's eye axes, meridians and structures based on measurements received from the topography measurement system and directs a treatment beam to form a radial fiducial mark incision. A tangible, non-volatile computer readable medium having instructions.
