METHOD AND APPARATUS FOR PATTERNED PLASMA-MEDIATED LASER TREPHINATION OF THE LENS CAPSULE AND THREE DIMENSIONAL PHACO-SEGMENTATION

摘要

Abstract A laser surgical system for making incisions in ocular tissue during a cataract surgical procedure comprising a laser system including a scanning assembly, a laser and an imaging device and a control system operably coupled to the laser system and configured to operate the imaging device to generate image data for ocular tissue of a patient's eye, the image data including lens interior image data for an interior portion of the lens of the patient's eye. The control system processes the image data to determine an anterior capsulotomy scanning pattern for scanning a focal zone of the laser beam for performing an anterior capsulotomy and operates the laser and the scanning assembly to scan the focal zone of the laser beam in the anterior capsulotomy scanning pattern to perform the anterior capsulotomy, wherein positioning of the focal zone is guided by the control system based on the image data.
