Laser therapy is a medical 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.

Information

Lasers can be used for many medical purposes. Because the laser beam is so small and precise, it allows health care providers to safely treat tissue without injuring the surrounding area. It can minimize bleeding and allow quicker recovery.

Lasers are often used to:

• Treat varicose veins
• Improve vision during eye surgery on the cornea
• Repair a detached retina of the eye
• Remove parts of the prostate
• Break up kidney stones
• Remove tumors

Lasers are also often used during skin and eye surgery.
