  • Clinical Trial Next for Laser Technique

Photonics Spectra
Jul 2012
Carl Zeiss Meditec AG of Dublin, Calif., and Jena, Germany, has received conditional approval from the FDA to initiate a clinical trial for its ReLEx smile procedure to correct myopia. The technique for refractive surgery combines femtosecond laser technology and precise lenticule extraction for minimally invasive laser vision correction in a single system, the VisuMax femtosecond laser. In lasik procedures, the excimer laser vaporizes tissue, while the ReLEx smile method generates a refractive lenticule in the intact cornea with the femtosecond laser. The surgeon then removes the lenticule through a small incision without having to move the patient to an excimer laser.

The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
