There are several types of lasers, each with different properties. They are used
to treat disease in a variety of ways. Some devices can be used to cut into tissue. Others
work by vaporizing thin layers of tissue.
Lasers are commonly used to perform surgery on the skin. Laser procedures can be used to
remove wrinkles, tattoos, birthmarks, tumors and warts. Other types of growths can also be
removed.
Lasers are also used to treat eye conditions. In some individuals, vision problems can be
corrected with laser surgery. Lasers can also be used to treat some forms of glaucoma and
eye problems related to diabetes.
Lasers are being incorporated into surgical procedures on other parts of the body, as
well. These include the heart, prostate gland, and throat. Lasers are also used to open
clogged arteries and remove blockages caused by tumors. Currently, lasers are only used in
part of these operations. This may change as laser technology improves. Knives and
scalpels may be completely eliminated one day.
Lasers have the advantages of increased precision and reduced rates of infection and
bleeding. Computers are used to control the intensity and direction of the laser beam.
This helps reduce human error.
Like any surgery, however, laser surgery can have complications. A person still runs the
risk of bleeding and infection from the surgery or a reactions to the anesthesia medicine.
Specific risks depend on the surgery being performed.
