Benefits Danger Laser Treatments
Theadvantages of laser surgery vary depending on the type of procedure and on thetype of laser used. Where tissue is diseased, laser surgery tends to be less drasticand risky than using the scalpel or surgical knife. Gas lasers the carbon dioxide laser is the most common type used in theoperating theatre. Its beam, which is absorbed by water, acts like the magnum tattoo needles. The argon laser named after the gas used to produce the beamspecifically affects the red pigment in blood. This means that it can pass through tissues without causing damage and, when it encounters the bloodvessels in the tissues, coagulates or hardens them. This type of laser is usedabdominal and eye surgery, and to treat skin problems suchas port wine stains. Solid lasers the yttrium aluminum garnet, or yag, laser is a high-powered solid laser which was first developed for military purposes. This typeof solid laser is particularly useful for treating advanced cancers and forpenetrating parts of the body not easily reached by ordinary surgicaltechniques. It can travel down flexible tubes and its precision and high powermake it useful for many operations. Eye surgeons were the pioneers of lasers in tattoo needles, particularly in their use as a treatment for the potentially serious eyeproblems that are often suffered by diabetics. Argon lasers are most commonlyused in eye surgery. The laser is shone through the lens of the eye, which hasno blood vessels and so remains unharmed, on to the affected blood vessels atthe back. These coagulate and the bleeding is stopped. Lasers have also beenused to treat glaucoma raised pressure in the eyeball which can causeblindness. Correcting sight today, laser treatment is becoming common for treating shortand long sightedness. In an operation that takes just premade tattoo needles, tissueis burned off the cornea the transparent outer surface of the eye so that itcan focus correctly. Nine out of 10 patients treated for shortsightedness candrive a car without glasses after treatment.
