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

1. A method of treating a lens of a patient'"'"'s eye, comprising:

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;

mechanically breaking the lens into a plurality of pieces along the cuts; and

removing the lens pieces from the patient'"'"'s eye.

2. The method of claim 1, further comprising:

deflecting the light beam using a scanner to form a softening treatment pattern of the light beam;

delivering the softening treatment pattern to the lens of the patient'"'"'s eye to create a plurality of softening cuts that soften one or more portions of the lens before the removal of the lens pieces from the patient'"'"'s eye.

3. The method of claim 2, wherein:

the cuts formed by the treatment pattern are larger than the softening cuts formed by the softening treatment pattern.
