Claim:
1. A method for performing a laser in situ keratomileusis (LASIK) procedure, the method comprising: obtaining a first image of the eye of a patient, wherein the first image of the eye is obtained concurrently with a wavefront measurement of the eye at a wavefront measurement device; processing the first image of the eye so as to identify an iris image; processing the first iris image so as to identify a plurality of natural tissue markers separated across the iris image; moving the patient to a laser eye surgery system; obtaining a second image of the eye while the eye is aligned with a femtosecond laser at the laser eye surgery system; identifying at least some of the plurality of markers within the second image of the eye; determining a rotational offset between the first image of the eye and the second image of the eye using the identified markers; and directing a femtosecond laser toward the eye per the rotational offset so as to perform the LASIK procedure.
