Laser Surgery Overview
What is laser surgery?
Laser surgery is a type of surgery that uses special light beams instead of instruments
for surgical procedures.
How does a laser work?
The functioning of a laser goes back to Albert Einstein's theory of stimulated emission of
radiation. It also includes other theories that help explain local tissue damage.
As the light beam hits the skin, the skin may either reflect the light away, scatter
the light, absorb the light, or let the light pass right through the different layers
of the skin.
Certain parts of the skin called chromophores absorb the light. When these chromophores
absorb the light, physical, mechanical, chemical, or temperature changes may occur
in the tissue.
There are many different types of lasers. They include the carbon dioxide laser, the
YAG (neodymium, or yttrium aluminum garnet) laser, and the argon laser. Each one works
differently and may be used for different treatment options. Laser light can be delivered
either continuously or intermittently. The wavelength of the laser determines the
target within the skin and the effect it may have.
What types of surgeries use lasers?
There are many reasons to use lasers in surgery. The following are some of the more
common reasons:
-
To shrink or destroy tumors
-
To help prevent blood loss by sealing small blood vessels
-
Refractive eye surgery
-
Dental procedures
-
To treat some skin conditions, including to remove warts, moles, tattoos, birthmarks,
acne, scars, wrinkles, and unwanted hair
