Fotona’s EndoVenous Laser Ablation (EVLA) treatment works by targeting Nd:YAG laser energy to the interior of a vein, causing the vein wall to shrink and seal shut. The healthy veins that surround the closed vein can then restore the normal flow of blood to the treated area. Safe, Effective and Minimally Invasive EVLA is principally effective on large truncal veins in the legs. Laser energy is delivered to the desired location inside the vein through an optical fiber and catheter. Laser treatments are less invasive than traditional surgical methods of varicose vein removal, have a lower complication rate, and are well tolerated by patients. Recovery time is short and the treatment produces good cosmetic results.
