Patent ID: 8663208

Claim:
A system for correcting the refractive condition of an eye having a cornea with an anterior surface and an endothelium, the system comprising: a laser subsystem operable to produce a non-ultraviolet, ultrashort pulsed beam in the range of 400 nm to 3000 nm; a patient interface configured to applanate the cornea during an intrastromal incision such that the patient interface is a planar surface, and the pulsed beam is directed through the patient interface and into the cornea; a scanner operable to direct the pulsed beam at the eye; and a controller coupled to the laser subsystem and the scanner, the controller configured to: determine an intrastromal incision pattern based on the refractive condition; and direct the scanner to intrastromally incise the pattern in the cornea with the pulsed beam through plasma mediated photodisruption, the refractive condition being corrected by the pattern intrastromally incised in the cornea following de-applanation of the cornea by the patient interface, wherein the pattern has a maximum radius of 5 mm, a minimum radius of 1 mm, a minimum depth from the anterior surface of the cornea of 50 microns, and a maximum depth of 50 microns toward the anterior surface from the endothelium of the cornea.
