Laser therapies are the latest medical modalities that use focused light to treat body conditions. Unlike most light sources, this technique uses laser light that is set to specific wavelengths. This allows it to increase the light intensity and to be focused into powerful beams.
In medicine, laser therapy allows surgeons to work at high levels of accuracy by focusing on a small body area - causing less damage to the surrounding tissues and organs. Compared to traditional surgery, laser therapy may cause less scarring, pain, and swelling. However, it requires repeated treatments and can be expensive.
How is Laser Therapy Done?
There are many laser therapy techniques that vary depending on the procedure. The most common procedures include low-light laser therapy, endoscopy and cold laser therapy.
An endoscopy is used to direct the laser light at the inside tissues and organs through a body opening. Endoscopic procedure is mainly used to take a piece of tissue (biopsy), shrink or destroy the tumor.
Low-light laser therapy and cold laser therapy are usually applied directly to the skin.
What is Laser Therapy Used For?
The common uses of various laser therapy techniques include:
- Shrinking or destroying the precancerous growths , tumors, and polyps
- Removing kidney stones
- Relieving symptoms of cancer
- Removing part of the prostate
- Improving vision
- Repairing a detached retina
- Treating pain, including back nerve pain
- Treating hair loss resulting from aging or alopecia
Lasers can have a sealing or cauterizing effect and may be used to seal:
- Blood vessels to help prevent blood loss
- Nerve endings to reduce pain after surgery
- Lymph vessels to limit the spread of tumor cells and reduce swelling
What are The Benefits?
Laser light is more precise than traditional surgical instruments, and cuts can be made clean, shorter, and shallower. This causes less damage and rapid repair of the tissue.
Laser procedures are usually shorter than most traditional surgeries. In most cases, you don’t have to spend the night in the hospital as they can often be done on an outpatient basis.
Laser therapy has fewer side effects. You may have less scarring, pain, swelling than with traditional surgeries.
