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.

[ What is claimed is:] [1.]1. 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) a computer system including,i) a means for receiving an image of the eye from the video-out port,ii) a means for processing the image, andiii) a means determining from the processed image whether the eye is properly positioned relative to the laser beam; andb) adjustment means for adjustably moving the patient relative to the laser beam based on input to said adjustment means from said computer system.
