Laser surgery was first introduced by the Russians where a laser beam is used to perform the surgery instead of a scalpel. Laser surgery is when a light beam is focused on a very small area and it heats the cell in that area until they burst. Laser surgery can be used for cosmetic and medical purposes. It can be classified in to various categories with each having a specific use. The color of the light beam used to perform the surgery is directly related to the type of surgery and the color of the tissue being treated.Laser surgery is commonly used on the eyes. The techniques involved are LASIK,Advantages of Laser Surgery Articles which is used to correct near and far-sightedness in vision, and photorefractive keratectomy, a procedure which permanently reshapes the cornea using laser to remove a small amount of tissue.The types of surgical laser are:Carbon dioxide (CO2)laser: Changes light energy to heat strong enough to reduce bleeding while the tissue is being cut Argon laser: This laser offers the penetration needed for eye surgery and superficial skin disorders Nd:YAG (yttrium aluminum garnet) laser: Capable of penetrating tissue more deeply than other lasers.Pulsed dye laser.

These deliver an intense burst of light into targeted areas of the skin. The different applications of laser surgeries include:EYE LASIK:Lasik surgery is used to treat refractive error. A refractive error is an eye disorder where visions become blurred. Lasik reshapes the safe laser részletre layers underneath the cornea and treats the refractive error.IntraLASIK: In this procedure instead of cutting the flap with a knife the surgeon uses a laser. Photorefractive keratectomy:This procedure involves reshaping the cornea without cutting the flap.Laser thermal keratoplasty: The surgeon makes burns in the cornea to make the surface deep thus allowing better near vision Phototherapeutic keratectomy (PTK):This removes the surface irregularities from the cornea Laser coagulation:The laser is used to treat blood vessels in the eye for various conditions Endovascular surgery The use of laser can assist in Laser endarterectom, Recanalization, angioplasties and Laser assisted vascular anastamosis.Foot and ankle surgery Lasers are used to treat several conditions in the foot and ankle.

They include benign and malignant tumors, in grown nails, club nail, fungus nail etc. Gastro-intestinal tract Lasers are used to treat several disorders in the Gastro-intestinal tract Advantages of laser surgery Laser surgeries are referred to as “bloodless surgery” as the procedures involve less bleeding than traditional surgery. The heat caused by the laser reduces the risk of infection as the surgical area is free of germs. Laser surgeries take less time and cost less also. Post-surgery there is less swelling or scarring. Recovery time is also less with laser surgery Post-surgery Care It is important to take care once the laser surgery is done. Pain relieving medicines are prescribed by the doctor along with instructions on how to take the medications. The recovery time period from the surgery varies from patient to patient and also depends on the type of surgery done. Laser surgery recoveries are normally faster than the traditional surgery that take place.
