Summary

This study compares two laser wavelengths (1470 nm and 1940 nm) for treating varicose veins in the legs. About 280 participants will receive one of the two laser treatments and be followed for five years. The goal is to see if the newer 1940 nm wavelength works as well as the standard 1470 nm one, while possibly reducing pain and complications.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: endovenous laser ablation (EVLA) at 1940 nm or 1470 nm
What this could lead to: If successful, this could show that a newer laser wavelength works just as well as the standard one while causing less pain or fewer side effects.
What could go wrong: This is a relatively small, early-stage comparison study. The newer wavelength may not prove superior, and individual results can vary. Long-term benefits are not yet established.
