What is LADARVision?

LADARVision® uses state-of-the-art technology that is uniquely different from other laser vision correction systems available today. The LADARVision® system incorporates the use of the LADARTracker™, a high-speed computerized eye tracking method that helps the doctor enhance your treatment. The LADARTracker™ had its genesis in technology research done by the National Aeronautic and Space Administration (NASA). Today, it’s incorporated into our new-generation excimer laser to provide superior precision, and less worry, for patients desiring laser correction of nearsightedness, farsightedness or astigmatism.

Your eyes are continually making very fine jumping movements – called “saccadic” movements – and they are beyond your control, no matter how hard you concentrate. They occur during all laser vision correction treatments. Our LADARVision® system, however, assists the doctor by scanning the eye an amazing 4,000 times per second. Then, using computer control, it makes micro-adjustments at speeds of 100 times per second to reposition the pinpoint laser beam between pulses of light, tracking even the smallest and quickest movements of your eye during treatment.

In addition, our LADARVision® system uses an ultra-small beam of cool laser light – one that’s less than a millimeter wide, a spot much smaller than the thickness of a single human hair. Using high-speed computer control, the LADARVision® system moves this tiny beam of light across the surface of the cornea very rapidly in a tiny, non-sequential and overlapping pattern. This helps create a smoother surface on your eye after your treatment, which has been attributed to quick visual recovery.

Finally, because of its state-of-the art active tracking system and its unmatched precision, our LADARVision® system means that LASIK laser vision correction is even easier for our patients. Now, you can relax and not worry about holding your eye perfectly still during your treatment.
