Claims
- 1. A method for treating an eye of a patient, the eye having a cornea and a pupil, the pupil having a center, the method comprising:aligning a laser delivery system with the pupil of the eye; designating a treatment center on the cornea, the treatment center being offset laterally from the center of the pupil; and ablating a region of the cornea by directing laser energy from the aligned laser delivery system according to a therapy profile centered at the treatment center, wherein the ablating step mitigates a refractive error produced by a prior treatment to the eye.
- 2. The method of claim 1, wherein the prior treatment comprises a prior ablation, and wherein the prior ablation was offset laterally from the center of the pupil.
- 3. A method for treating an eye of a patient, the eye having a cornea, the method comprising:aligning a laser delivery system with a first center of the eye; designing a treatment center on the cornea, the treatment center being offset laterally from the first center of the eye; and ablating a region of the cornea by directing laser energy from the aligned laser delivery system according to a therapy profile centered at the treatment center, wherein the ablating step mitigates a refractive error produced by a prior treatment to the eye.
- 4. The method of claim 3, wherein the prior treatment comprises a prior ablation, and wherein the prior ablation was offset laterally from the first center.
