An eye tracking and positioning system for use with a refractive laser system includes a camera interface, a computer, and a system for moving the patient relative to the laser beam. The computer includes a video frame grabber which extracts images of the eye from the camera, and is programmed to perform an eye tracking algorithm. The eye tracking algorithm calculates the exact center of the eye pupil, and compares the center with the desired location of the laser beam, as determined by a surgeon, with an image processing algorithm. If the relative location of the eye center and the laser beam fall outside a predetermined value, the patient chair, and thereby the patient, is repositioned relative to the laser beam, as opposed to the laser beam being repositioned relative to the patient. The repositioning counters the movement of the eye.
An eye tracking and positioning system for use with a refractive laser system which produces a laser beam for performing surgery on an eye of a patient, the refractive laser system having a video-out port, said eye tracking and positioning system comprising:
A method for positioning an eye of a patient relative to a laser beam produced by a refractive laser system for performing eye surgery on the eye, the method including:
