  • Device and method for measuring the diameter of the iridocorneal angle
    Publication number: 20050110947
    Abstract: A device and method for measuring the iridocorneal angle including: a light source (14) designed to reveal the differences of contrast in an image; image capture unit (10); and image processing system (22) connected to the image capture unit (10). The image processing system (22) receives an image of the eye captured by the image capture unit (10) and supplies in output a value of the iridocorneal angle, the value being obtained based on the analysis of the contrast differences in the image.

  • Multiple wavelength laser system
    Patent number: 5331649
    Abstract: A laser system having plural optical paths, each with a dielectric mirror for extracting a different wavelength of light from a laser beam, and a laser medium movable with respect to the different optical paths for injecting the laser beam into a desired optical path. The laser medium is mounted to a motor driven carriage for moving the laser medium with respect to the different optical paths.
