The word Laser stands for Light Amplification by the Stimulated Emission of Radiation. The working of the lasers is based on the fact, that an intense beam of bright light traveling in one direction, can cut, seal or vaporize skin tissue and blood vessels. It has the capability to produce one specific color (wavelength) of light varied in its intensity and pulse duration.
The laser surgery can be used to:
- Remove tumors (brain, liver).
- With minimal damage to surrounding healthy tissue.
- With minimal scarring.
- Seal small blood vessels to reduce blood loss .
- Seal lymph vessels to reduce swelling and decrease the spread of tumor cells .
- Seal nerve endings to reduce postoperative pain .
- Remove warts, moles, and tattoos .
- Reduce the appearance of skin wrinkles, scars, and other skin blemishes .
- Remove hair.
Following benefits can be achieved by laser surgery:
- Improved therapeutic results.
- Reduced risk of infection.
- "Bloodless" surgery.
- Alternative to traditional scalpel surgery.
- Less scarring.
- Precisely controlled surgery limiting injury to normal skin.
- Safe and effective outpatient.
There are different types of lasers, including carbon dioxide (CO2) laser, YAG (yttrium aluminum garnet) laser, and pulsed dye laser. Each of these have specific uses. The color of the light used is associated with the type of surgery being performed and color of the tissue being treated.
