Laser therapy uses low-level lasers or light-emitting diodes to emit monochromatic light that can penetrate tissues. This light interacts with biomolecules in cells to help restore normal cell function and morphology. Laser therapy is used for a variety of medical purposes, including wound healing and treatment of musculoskeletal injuries and chronic or degenerative conditions. It can eliminate growths, cauterize blood vessels, and be used for surgeries like eye procedures.
