Abstract
An orientation method for corrective eye surgery that registers pairs of eye images taken at different times and with the patient in different positions includes retrieving reference digital image data on an eye of the patient, including image data on an extracorneal eye feature. Real-time image data are collected that include image data on the extracorneal eye feature. A combined image is displayed of a superposition of the data sets, and a determination is made as to whether the combined image indicates an adequate registration between them based upon the extracorneal eye feature data in the two data sets. If the registration is not adequate, one of the data sets is manipulated until an adequate registration is achieved. A system is directed to apparatus and software for orienting a corrective program for eye surgery.
