Abstract
A method of treating a cataractous lens of a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form a treatment pattern, delivering the treatment pattern to the lens of the patient's eye to create a plurality of cuts in the form two or more different incisions patterns within the lens to segment the lens tissue into a plurality of patterned pieces, and mechanically breaking the lens into a plurality of pieces along the cuts. A first incision pattern includes two or more crossing cut incision planes. A second incision pattern includes a plurality of laser incision each extending along a first length between a posterior and an anterior surface of the lens capsule.
