Patent Images
1. A method for alignment for refractive treatment of a patient'"'"'s eye, comprising:
- making a diagnostic measurement of the patient'"'"'s eye;
acquiring a first image including an iris image of the patient'"'"'s eye;
determining a spatial relationship between the first image and the diagnostic measurement;
developing the refractive treatment for the patient'"'"'s eye based upon the diagnostic measurement;
acquiring a second image of the patient'"'"'s eye; and
aligning the second image, including the determined spatial relationship with the first image in preparation for performing the refractive treatment.

Abstract
A system and method are provided in which an iris or eye image is taken during a refractive diagnostic analysis. The image is employed for aligning data from the analysis with data from other refractive analysis instruments, as well as aligning a refractive surgical tool, such as a laser, with the eye for treatment. Further, the stored iris image is compared with the patient'"'"'s iris before treatment, verifying that the correct eye is to be treated with a developed treatment pattern. A variety of refractive instruments can be used, such as corneal topography systems and wavefront aberration systems.
