Healing Touch of Lasers:

Contrast the above application  of lasers with their uses in medicine where the laser is working wonders. A laser can be applied with almost perfect precision in surgery. It can bum away diseased tissue without damaging the healthy tis'sue nearby. The tissues are cut neatly and without any oozing of blood, and they can also be joined  together. Lasers are completely sterile, because bacteria cannot survive exposure to a laser beam. Today, lasers are routinely used in eye surgery to treat detached retinas and to destroy abnormal blood vessels that form in the retinas of diabetic patients. Earlier these diseases would result in blindness. For such patients, laser is indeed a "miracle light". Lasers have become standard equipment for ear, eye and other delicate forms of surgery. From removing brain tumours, to stoppiag bleeding from ulcers, and treating cancer of  the bladder, lasers find a wide use in medicine.
