MEASUREMENT/DISPLAY/RECORD/PLAYBACK OF WAVEFRONT DATA FOR USE IN VISION CORRECTION PROCEDURES

One embodiment is an apparatus/system for providing feedback to a procedure. The apparatus includes a real time wavefront sensor for measuring the wavefront of an optical beam, a real time video camera for capturing/recording a scene where the optical beam comes from, a computer for processing the captured/recorded wavefront data and synchronizing the data with the video and outputting the synchronized information to a display, and a display for simultaneously displaying the synchronized wavefront and video information. Another embodiment of the present invention is a method for providing feedback to a procedure. The method involves the steps of measuring the wavefront of an optical beam with a real time wavefront sensor; capturing a video of a scene from which the optical beam comes; processing the captured/recorded wavefront data and synchronizing it with the video; and simultaneously displaying the wavefront information with the video on the same display screen.
