1. A laser surgical system for making incisions in ocular tissues 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;

    an imaging device configured to acquire point by point image data from locations distributed throughout a volume of a crystalline lens of the patient and construct one or more images of the patient'"'"'s eye tissues from the image data, wherein the one or more images comprise an image of at least a portion of the crystalline lens; and

    a control system operably coupled to the laser system and configured to;

    operate the imaging device to generate image data for patient'"'"'s crystalline lens;

    process the image data to identify a location for each of one or more targets in the lens of the patient;

    process the image data to determine a treatment scanning pattern for scanning a focal zone of the laser beam for performing one or more incisions in the lens capsule; and

    operate the laser and the scanning assembly to scan the focal zone of the laser beam in the treatment scanning pattern at each location of the one or more targets, wherein positioning of the focal zone is guided by the control system based on the location of the one or more targets so as to perform the one or more incision in the lens capsule.
