System and method of intrastromal refractive correction. The system includes a laser source operable to produce a pulsed beam, a scanner operable to direct the pulsed beam at the eye, and a controller coupled to the laser source and the scanner. The controller determines an intrastromal incision pattern based on a refractive condition of an eye, and directs the scanner to intrastromally incise the pattern in an applanated cornea with the pulsed beam. Following de-applanation, the cornea is reshaped in response to the intrastromal incision pattern to correct the refractive condition.

대표청구항 ▼

1. 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; anda controller coupled to the laser subsystem and the scanner, the controller configured to: determine an intrastromal incision pattern based on the refractive condition; anddirect 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. 2. The system of claim 1, further comprising a controller configured to: determine an intrastromal incision pattern based on a correction of myopia; anddirect the scanner to intrastromally incise the pattern in the cornea with the pulsed beam through plasma mediated photodisruption, the myopia being corrected by the pattern intrastromally incised in the cornea following de-applanation of the cornea by the patient interface. 3. The system of claim 2, wherein the controller is further configured to direct the scanner to intrastromally incise the pattern in the cornea with the pulsed beam through plasma mediated photodisruption, the cornea reshaping in response to the intrastromal pattern incised in the cornea to correct for myopia. 4. The system of claim 1, further comprising a controller coupled to the laser subsystem and the scanner, the controller configured to: determine an intrastromal incision pattern based on myopia; anddirect the scanner to intrastromally incise the pattern in the cornea with the pulsed beam through plasma mediated photodisruption, the myopia being corrected by the pattern intrastromally incised in the cornea following de-applanation of the cornea by the patient interface, wherein the pattern is configured to reshape the cornea; andthe 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. 5. The system of claim 1, wherein the pattern comprises a plurality of spots, each spot of the plurality of spots associated with a pulse beam energy of 0.01 μJ to 1 μJ. 6. The system of claim 1, wherein the intrastromal incision pattern comprises a plurality of intrastromal incisions radially oriented about an optical axis of the eye, each incision of the plurality of intrastromal incisions extending between an inner radius of the optical axis and an outer radius of the optical axis. 7. The system of claim 6, wherein the inner radius is 6 mm, the outer radius is 9.5 mm, and the plurality of intrastromal incisions comprises 32 intrastromal incisions. 8. The system of claim 6, wherein at least one incision of the plurality of intrastromal incisions has a zig-zag cross-section.
