The Idea Behind Medical Laser Surgical Procedures
Laser surgery is a medical procedure that uses laser light to remove diseased tissues or to treat bleeding blood vessels. Medical lasers have been used for many different types of procedures such as the cleaning of arteries (plaque removal), cataracts, neurosurgery, skin cancer, varicose vein, gall and kidney stone, nosebleeds, ulcers, warts, endometriosis and cosmetic procedures. LASIK, a well known laser eye procedure, is widely used. It's an acronym for Laser Assisted In Situ Keratomilensis. LASIK reshapes the eye’s cornea. Lasers use light functions and properties to work. Normal light, like sunlight, is produced from its source in all directions and is called spontaneous emission. Laser light is generated within a medium (a type of device or environment). The atoms within the medium become excited but still require some form of stimulus, or a secondary energy source to emit light. This produces a steady beam of light that can stay consistent with depth of incision needed and also to be accurate.
"By 1962 efforts at using the laser for medical purposes were under-way. The ruby crystals through which early lasers were transmitted did not lend themselves to medical use. It wasn't until argon (a colorless, oderless intert gas) gas was used in place of the ruby that the correct color and intensity of the laser beam was able to be harnessed for surgery".
