1. 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.
