1. A system for providing laser shot patterns to an eye, for the correction of an induced astigmatism of the eye, the system comprising:
a therapeutic laser for producing a laser beam;
optics for receiving the laser beam;
a control system for controlling the delivery of the laser beam to an eye;
the control system comprising:
a) a lens laser shot pattern for sectioning a lens of the eye, and;
b) a sub-Bowman's laser shot pattern for providing an arcuate cut in a cornea below a Bowman's membrane of the eye, wherein the sub-Bowman's laser shot pattern is configured to address an induced astigmatism in the eye.
 
11. A method for performing surgery and reducing an induced astigmatism by using a laser system comprising:
positioning an eye of a patient with respect to a laser system;
directing the laser system to perform a cataract surgery on the positioned eye;
directing the laser system to deliver a pair of arcuate laser shot patterns to a cornea of the eye after performing the cataract surgery, wherein each of the pair of arcuate laser shot patterns is oriented along a steep axis so as to be intersected by the steep axis, thereby reducing an induced astigmatism of the eye while not disrupting a Bowmans' membrane of an eye or an epithelium of the eye.
