🌟Feedback from our client, Excellent surgical results, praised by doctors and patients.

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.

Our S1-K12 model with 1470nm 12W was used here to finish the whole treatment. Confirmed by clinical statistics, 1470nm's recommended power ranges from 5W to 10W.

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.

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

In this operation, our S1 Pro was used here to do the treatment with just 9 Watts, which is clinically proven and safe.

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.
