Method and Apparatus for Patterned Plasma-Mediated Laser Trephination of the Lens Capsule and Three Dimensional Phaco-Segmentation

A laser surgical system for making incisions in ocular tissue during a cataract surgical procedure, the system comprising:

• a laser system comprising a scanning assembly, a laser operable to generate a laser beam configured to incise ocular tissue, 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;
• process 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
• operate 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.
