Iris recognition
Like your fingerprints, no two irises are the same and this can be used to provide a unique identification. The Zyoptix z100 system can scan your irises during the Zywave measurement and maps the entire iris, generating a unique digital Zy-ID for each eye. This map of the iris forms the foundation from which the Multi-Dimensional Eyetracker operates. The Zy-ID is the unique digital file that contains the patient's laser eye treatment information, including the map of the Iris. Further reading
