LASER SYSTEM AND METHOD FOR CORRECTION OF INDUCED ASTIGMATISM

摘要

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 induced astigmatism. The systems, apparatus and methods further provide laser systems that can provide these incisions at or below Bowman's membrane.

主权项

1. A system for providing laser shot patterns to an eye, for the correction of induced astigmatic aberrations of the 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 an ophthalmic surgical procedure is generated, 2) a laser shot pattern for sectioning a lens of an eye is generated, wherein one or more of the laser shot pattern for performing the ophthalmic surgical procedure and the laser shot pattern for sectioning a lens of an eye causes induced astigmatism to the eye; 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 either Bowman's membrane of the eye or an epithelium of the eye and reduces the induced astigmatism of the eye.
