Patent ID: 6951556

Claim:
A method for correcting an off-center laser ablation in the cornea, in which the original ablated area has a center that is offset from the correct optical center of the cornea, comprising the steps of: determining the correct optical center of the cornea and the offset location of the ablation; and performing a supplemental laser ablation on the cornea with the total energy per area of cornea of the supplemental laser treatment increasing in a direction defined by a vector originating at the offset center and going toward the correct optical center; in which the supplemental laser ablation step includes the step of providing a laser masking device which moves in the direction from the offset center toward the correct optical center, and in which the speed of the masking device is inversely proportional to the product of the distance of the offset center from the correct optical center times the number times the number of diopters of optical correction that were placed in the original ablation.
