Laser Treatment
Laser treatment a boon to many medical procedures
Laser treatment has found its way into all kinds of medical procedures today. In the 50 years since lasers were invented, the prevalence of using light beams to treat various illnesses and conditions has increased dramatically.
In fact, lasers have become so popular that people have even forgotten that the word "laser" is actually a coined term. It stands for "light amplification by stimulated emission of radiation." The properties of this concentrated beam of light, at various ranges in the color spectrum, have been little short of amazing.
Dermatologists use laser treatment to remove birthmarks and tattoos, smooth wrinkles, treat acne and acne scars and remove unwanted hair. Ophthalmologists use this procedure to restore vision, removing the need for eyeglasses or contacts. Laser treatments are even showing up in major surgery such as gallbladder removal and hair restoration.
Dermatologists and plastic surgeons in particular have found many uses for laser treatment. Both kinds of specialists are now using lasers on such conditions as:
* Hypertrophic scars, which are firm, raised bundles of collagen that collected improperly during wound healing.
* Keloids, which are raised, reddish-purple scars that are thicker and harder than the hypertrophic kind of scar and extend beyond the margins of the wound.
* Atrophic scars, which are depressions in the skin also called "pock marks," resulting from an inflammatory skin disease such as chicken pox or cystic acne
One of the most innovative uses of lasers has been its application to enlarged or twisted blood vessels known as varicose veins. This form of the procedure is known as "endovenous laser ablation," or EVLA.
EVLA has much to recommend it over earlier treatments for varicose veins. Previously varicose veins were treated with an invasive surgical procedure known as "vein stripping" that involved a painful recovery period. In contrast, EVLA is a laser procedure that can be performed in a doctor's office or clinic using only local anesthesia.
EVLA works by directing laser energy through a sheath into the vein, where a variety of laser wavelengths are used to kill off the excess tissue. This is delivered continuously along the varicose vein as the laser fiber is slowly withdrawn from the sheath. The result is to reduce the enlarged venous tissue and remove both the pain and unsightliness of the varicose vein.
Laser treatment has been made possible by continuous improvement in both machines and techniques. In addition doctors and technicians have continued to enhance their skills as using this remarkable medical tool.
