OPHTHALMIC LASER SURGICAL SYSTEM AND METHOD FOR WAVEFRONT-GUIDED CORNEAL LENTICULE EXTRACTION FOR VISION CORRECTION
A ophthalmic laser-assisted corneal lenticule extraction procedure that uses wavefront measurements to guide the formation of the corneal lenticule. The wavefront map measured from a free eye using a wavefront aberrometer is registered to the cornea of a docked eye based on comparisons of iris images and corneal markings. The docked-eye cornea-registered wavefront map is then corrected to be consistent with the Munnerlyn formula for the spherical power, and adjusted for any physician adjustments and/or myopia error due to a flat add in the lenticule, using Zernike polynomials. The corrected and adjusted wavefront map is then used to calculate the profiles of the bottom and top lenticule incisions in the applanated cornea, where higher-order components in the wavefront map are distributed to the bottom lenticule incision alone and lower-order components in the wavefront map are distributed to both the bottom and the top lenticule incision.

Treatment apparatus for surgical correction of defective eyesight, method of generating control data therefore, and method for surgical correction of defective eyesight
A treatment method and apparatus for surgical correction of defective-eyesight in an eye of a patient, wherein a laser device is controlled by a control device, said laser device separating corneal tissue by irradiation of laser radiation to isolate a volume located within a cornea, wherein the control device controls the laser device to focus the laser radiation, by providing target points located within the cornea, into the cornea, wherein the control device, when providing the target points, allows for focus position errors which lead to a deviation between the predetermined position and the actual position of the target points when focusing the laser radiation, by pre-offsets depending on the positions of the respective target points to compensate for said focus position errors.

SYSTEM AND METHOD OF CORNEAL CROSS-LINKING
The disclosure provides a system that may: receive data associated with multiple locations associated with a cornea of an eye; adjust at least one lens, based at least on diameter information of the data associated with at least one of the multiple locations, to set a diameter of a laser beam; and for each location of the multiple locations: determine if the eye has changed from a first position to a second position; if the eye has not changed from the first position to the second position, adjust, based at least on the location, at least one mirror; if the eye has changed from the first position to the second position, adjust, based at least on the location and based at least on the second position, the at least one mirror; produce the laser beam; and direct the laser beam to the location for a period of time.
DEVICES AND METHODS FOR CORRECTING HIGH-ORDER OPTICAL ABERRATIONS FOR AN EYE USING LIGHT
Devices and methods for correcting and compensating high order aberrations from an eye using light are described. A method includes providing a first light to a first region of an optical element, thereby modifying a refractive index profile in the first region of the optical element, while offsetting a center of the first region with respect to a center of the optical element. The refractive index profile is configured to compensate for an optical aberration of a subject's eye.
