ABSTRACT:
An orientation system for corrective eye surgery includes a camera for performing a first image mapping of a patient's eye using a predetermined eye feature and software for processing the first image map to determine an edge location of the feature. A second image mapping of the eye is performed with the patient in a different position. The second image map is processed to locate the predetermined eye feature. Correlation of the mappings is used to calculate an orientational change of the eye between the two positions. The data are used to calculate an adjustment to be applied to a corrective prescription for application by the surgical procedure.
