Dual Wavelength Surgical Laser for Endovenous (EVLT) Treatment

It is well known that the advantage of endovenous laser therapy at 1470nm is the higher absorption coefficient of water compared to 980nm. Therefore, laser radiation can be applied precisely into the vein wall. Additionally, the process requires less total energy and generates lower heat.

Advantages of 1470nm for EVLT

The energy of 1470nm semiconductor laser can be absorbed by hemoglobin and cell water. At the same time, 1470nm wavelength laser has strong tissue absorption rate and shallow penetration depth, and the energy directly acts on the blood vessel wall, which can completely and evenly close the blood vessel.

1940nm wavelength-the future for EVLT

Due to the 4-fold higher absorption of the 1940nm laser in the interstitial water of the vein wall compared to 1470nm lasers, veins can be effectively closed with only 4-6 Watts and significantly less energy

Laser 1470nm EVLT Endovenous Laser Ablation of Varicose Veins

Endovenous laser varicose vein surgery is a procedure that uses heat from a laser to reduce varicose veins. Varicose veins are swollen, bulging veins that often happen on the thighs or calves. A laser is a device that sends a thin beam of radiation in the form of light.
