Endovenous Laser Therapy (EVLT) uses laser energy to seal malfunctioning veins closed, providing a high success rate of 98% for treating varicose and vein disease. EVLT is convenient as each procedure takes under 15 minutes and requires no hospitalization, allowing immediate return to normal activities. It has low risks as it is non-surgical, non-invasive, requires no anesthesia or large incisions, and causes little scarring.
