Laser treatment is a type of treatment for varicose veins. Until recently, laser treatment was mainly used for treatment of spider veins on the face. However, newer laser technology can now effectively treat varicose veins as well. There are several types of lasers that may be used to treat varicose veins. The physician inserts a tiny fiber into a varicose vein through a catheter. The fiber sends out laser energy that destroys the diseased portion of your varicose vein. The vein closes and your body eventually absorbs it.
