Abstract
Embodiments of this invention generally relate to ophthalmic laser procedures and, more particularly, to systems and methods for photorefractive keratectomy. In an embodiment, an ophthalmic surgical laser system comprises a laser source generating a pulsed laser beam and a laser delivery system delivering the pulsed laser beam to a cornea of an eye. A patient interface couples to and constrains the eye relative to the laser delivery system. A controller controls the laser delivery system to perform an anterior surface volume dissection on the cornea.
Claims10
An ophthalmic surgical laser system comprising:
- a laser source generating a pulsed laser beam;
- a laser delivery system delivering the pulsed laser beam to a cornea of an eye;
- a patient interface coupling to and constraining the eye relative to the laser delivery system;
- a controller controlling the laser delivery system to perform an anterior surface volume dissection on the cornea.

4-11. (canceled)
A method for correcting vision in an eye using an ophthalmic surgical laser system, comprising the steps of:
- coupling the eye to a patient interface to constrain the eye relative to the system;
- generating a pulsed laser beam by a laser source;
- delivering the pulsed laser beam to a cornea in the eye by a laser delivery system;
- and
- controlling the laser delivery system by a controller to perform an anterior surface volume dissection in the cornea.
The ophthalmic surgical laser system of claim 5, wherein the laser delivery system scans the cornea by point-to-point scanning.
The ophthalmic surgical laser system of claim 5, wherein the laser delivery system scans the cornea by fast scan line scanning.
