1. A laser surgical system for making incisions in a lens of a patient's eye during a cataract surgical procedure, the system comprising:
a laser system comprising a scanning assembly and a laser operable to generate a laser beam configured to incise the lens of the eye; and
a control system operably coupled to the laser system and configured to:
determine a lens fragmentation scanning pattern for scanning a focal zone of the laser beam in a cutting region in a posterior portion of the lens of the eye, the cutting region being at least partially defined by an anterior cutting boundary, a posterior cutting boundary and a lateral cutting boundary of the lens, the cutting region including the optical axis of the eye and a peripheral portion of the lens spaced laterally from the optical axis;
operate the laser and the scanning assembly to scan the focal zone of the laser beam at a first focal point located at a first depth in the lens of the eye and to scan the beam on the eye while focused at the first depth so as to create a first incision pattern in the lens corresponding to a first portion of the lens fragmentation pattern, and
operate the laser and scanning assembly to scan the focal zone of the laser beam at a second focal point located at a second depth in the lens of the eye anterior to the first depth, and to scan the beam on the eye while focused at the second depth so as to create a second incision pattern in the lens corresponding to a second portion of the lens fragmentation pattern within the cutting region at the second depth, wherein an energy of the laser pulses scanning the second incision pattern is higher when the second focal point is scanned in the peripheral portion than when the second focal point is scanned in a central portion near the optical axis.
