Abstract
A method of treating a lens of a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form a treatment pattern of the light beam, delivering the treatment pattern to the lens of a patient's eye to create a plurality of cuts in the lens in the form of the treatment pattern to break the lens up into a plurality of pieces, and removing the lens pieces from the patient's eye. The lens pieces can then be mechanically removed. The light beam can be used to create larger segmenting cuts into the lens, as well as smaller softening cuts that soften the lens for easier removal.
Claims (6)
1 . A system for treating a cataractous lens of a patient's eye, comprising:
a. a laser source for generating a light beam;
b. a scanning system for deflecting the light beam to form a treatment pattern of the light beam; and
c. a controller operably coupled to the laser source and scanning system and configured to operate the scanning system to form the treatment pattern in the lens to create a plurality of cuts in the lens in the form two or more different incision patterns within the lens to segment the lens into a plurality of patterned pieces, the incision patterns comprising: a first incision pattern comprising a plurality of laser incision planes each extending along a first length between a posterior and an anterior surface of a lens capsule, wherein the plurality of the laser incision planes of the first incision pattern comprise two or more crossing cut incision planes, wherein at least one of the crossing cut incision planes is inclined in a side cross-sectional view that passes through an optical axis of the eye.
2 . The system of claim 1 , wherein at least another one of the crossing cut incision planes is inclined in another side cross-sectional view that passes through the optical axis of the eye.
3 . The system of claim 1 , wherein the incision pattern further comprises a second incision pattern comprising one or more laser incisions, each extending along a first length between a posterior and an anterior surface of the lens capsule.
