1470nm Varicose Vein Laser

Saphenous Laser Ablation at 1470 nm Targets the Vein Wall, Not Blood
2 comparative studies have demonstrated that patients treated with water-specific laser wavelengths (WSLW) reported less postoperative pain, used less painkillers, and were less likely to have ecchymosis.
There is increasing focus on reducing perioperative pain and bruising while maintaining high saphenous vein ablation rates. A WSLW has become commercially available at 1470 nm in a diode platform. Because the 1470-nm wavelength is preferentially absorbed by water 40 times more than a 980-nm wavelength, the manufacturer hypothesized that it would more readily target the vein wall and more readily ablate veins at lower energy densities, with fewer side-effects.
