In May 2005 VISX Inc was acquired by Advanced Medical Optics (AMO). VISX, Incorporated is in the development of proprietary technologies and systems for laser vision correction (LVC), which relies on a computerized laser to treat nearsightedness, astigmatism and farsightedness with the goal of eliminating or reducing reliance on eyeglasses and contact lenses. The VISX Excimer Laser System is a fully integrated medical device incorporating an excimer laser and a computer-driven workstation. The VISX System removes submicron layers of tissue from the surface of the cornea to reshape the eye so that images are properly focused on the retina, which in turn reduces or eliminates the need for corrective eyewear. The VISX System is also designed to treat certain types of corneal pathologies in an outpatient procedure known as PhotoTherapeutic Keratectomy or PTK. In addition to marketing the VISX System, the Company supplies proprietary optical memory cards, called VisionKey, which are sold separately and control the use of the VISX System.
