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.
