Laser therapies are medical treatments that use focused light. Unlike most light sources, light from a laser (which stands for light amplification by stimulated emission of radiation) is tuned to specific wavelengths. This allows it to be focused into powerful beams. Laser light is so intense that it can be used to shape diamonds or cut steel.
In medicine, lasers allow surgeons to work at high levels of precision by focusing on a small area, damaging less of the surrounding tissue. If you have laser therapy, you may experience less pain, swelling, and scarring than with traditional surgery. However, laser therapy can be expensive and require repeated treatments.

Some laser surgeries, such as cosmetic skin and eye surgeries, are considered elective surgeries. Some people decide the potential risks can outweigh the benefits of these types of surgeries. For example, some health or skin conditions may be aggravated by laser surgeries. As with typical surgery, poor overall health also increases your risk of complications.
