There is provided a system, apparatus and methods for developing laser systems that can create precise predetermined clear corneal incisions that are capable of reducing astigmatism. The systems, apparatus and methods further provide laser systems that can provide these incisions at or below Bowman's membrane and in conjunction a precise predetermined capsulotomy shot pattern.
1. A system for providing laser shot patterns to an eye, the system comprising: a therapeutic laser for producing a laser beam;optics for receiving the laser beam and directing the laser beam to an eye so that: 1) a laser shot pattern for performing a capsulotomy is generated, 2) a laser shot patter
1. A system for providing laser shot patterns to an eye, the system comprising: a therapeutic laser for producing a laser beam;optics for receiving the laser beam and directing the laser beam to an eye so that: 1) a laser shot pattern for performing a capsulotomy is generated, 2) a laser shot pattern for sectioning a lens of an eye is generated; and 3) a laser shot pattern for providing a sub-Bowman's membrane arcuate cut in a cornea of the eye, wherein the laser system provides the sub-Bowman's membrane arcuate cut in a manner that does not disrupt Bowman's membrane of the eye and reduces astigmatism of the eye; andwherein the sub-Bowman's membrane arcuate pattern is oriented along a steep axis so as to be intersected by the steep axis. 2. The system of claim 1 wherein the sub-Bowman's membrane arcuate pattern has about a 3 mm radius. 3. The system of claim 1 wherein the sub-Bowman's membrane arcuate pattern has an arc of about 60°. 4. The system of claim 1 wherein the sub-Bowman's membrane arcuate pattern has an arc of about 90°. 5. The system of claim 1 wherein the sub-Bowman's membrane arcuate pattern has an arc of about less than 90° and about greater than or equal to 60°. 6. The system of claim 1 wherein the sub-Bowman's membrane arcuate pattern has about a 3 mm radius and an arc of about 90° to about 60°. 7. A system for reducing astigmatism associated with replacement of a natural human lens with a lens replacement material, the system comprising: a laser for providing a laser beam;a controller in communication with the laser and controlling the laser beam so as that a shot pattern is generated on an eye, wherein the shot pattern comprises two arcuate patterns oriented on the eye along a steep axis so as to be intersected by the steep axis, wherein the system delivers the laser beam generating the shot pattern below Bowman's membrane of the eye to treat astigmatism of the eye. 8. The system of claim 7 wherein each of the pair of arcuate patterns has about a 3 mm radius. 9. The system of claim 7 wherein each of the pair of arcuate patterns has an arc of about 60°. 10. The system of claim 7 wherein each of the pair of arcuate patterns has an arc of about 90°. 11. The system of claim 7 wherein each of the arcuate patterns has an arc of about less than 90° and about greater than or equal to 60°. 12. The system of claim 7 wherein each of the pair of arcuate patterns has about a 3 mm radius and an arc of about 90° to about 60°. 13. The system of claim 7 wherein each of the pair of arcuate patterns has a depth of about less than or equal to a thickness of the cornea of the eye. 14. A system for providing an arcuate shot pattern to an eye, the system comprising: a therapeutic laser for producing a laser beam;optics for receiving the laser beam and directing the laser beam to an eye so that an arcuate shot pattern having a depth of about less than or equal to a thickness of a cornea of the eye is generated, wherein the laser system provides the arcuate shot pattern in a manner that does not disrupt an epithelium of the eye and reduces astigmatism of the eye; andwherein the arcuate shot pattern is oriented along a steep axis so as to be intersected by the steep axis. 15. The system of claim 14 wherein the arcuate shot pattern has about a 3 mm radius. 16. The system of claim 14 wherein the arcuate shot pattern has an arc of about 60°. 17. The system of claim 14 wherein the arcuate shot pattern has an arc of about 90°. 18. The system of claim 14 wherein the arcuate shot pattern has an arc of about less than 90° and about greater than or equal to 60°. 19. A method for performing cataract surgery and reducing residual 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 capsulotomy on the positioned eye;directing the laser system to deliver a pair of arcuate laser shot patterns to a cornea of the eye, 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 astigmatism of the eye while not disrupting an epithelium of the eye. 20. The method of claim 19 wherein each of the pair of arcuate laser shot patterns has about a 3 mm radius. 21. The method of claim 19 wherein the arcuate laser shot pattern has an arc of about 60°. 22. The method of claim 19 wherein the arcuate laser shot pattern has an arc of about 90°. 23. The method of claim 19 wherein the arcuate laser shot pattern has an arc of about less than 90° and about greater than or equal to 60°. 24. The method of claim 19 wherein the arcuate laser shot pattern has about a 3 mm radius and an arc of about 90° to about 60°. 25. The method of claim 19 wherein the arcuate laser shot pattern has a depth of about less than or equal to a thickness of the cornea of the eye.
