Laser therapy is a treatment that uses a strong beam of light to cut, burn, or destroy tissue. The term LASER stands for "Light Amplification by Stimulated Emission of Radiation."
The laser light beam comes from safe sources so that it poses no health risks to the patient or medical team.
Lasers can be used for many medical purposes. Because the laser beam is so small and precise, it allows doctors to safely treat tissue without injuring the surrounding area.
Lasers are often used during these procedures:
- Treating varicose veins
- Corneal eye surgery to improve vision
- Repairing a detached retina of the eye
- Removing the prostate
- Removing kidney stones
- Removing tumors
- Skin surgery
