RF Ablation vs Laser Surgery for Varicose Veins — Which Is Better in 2026?

Both RF Ablation and laser surgery are far better than old-fashioned vein stripping. But when comparing the two modern options, RF Ablation holds several key advantages. Here's what the evidence says.

How They Work — The Key Difference

RF Ablation (Radiofrequency Ablation): A catheter delivers radiofrequency energy to heat the vein wall uniformly to around 120°C, causing it to collapse and seal. The controlled, even heating is precisely regulated by the machine.

EVLT (Endovenous Laser Treatment): A laser fibre delivers laser energy directly into the vein. The heat is less uniform, often causing more intense local heating at points where the fibre contacts the vein wall.

Head-to-Head Comparison

What Do Major Studies Say?

Multiple randomised controlled trials comparing RF Ablation and laser have consistently found that RF Ablation causes less post-operative pain and bruising while achieving equivalent or slightly better long-term closure rates. The RECOVERY trial and EVOLVeS study both showed patients treated with RF Ablation returned to normal activity faster and reported higher satisfaction scores.

When Is Laser Preferred?

Laser may be preferred for very tortuous (twisted) or superficial veins where the catheter design offers an advantage, or in specific anatomical situations. Your interventional radiologist will recommend the best option based on your Doppler ultrasound mapping.

The Bottom Line

For the majority of patients, RF Ablation is the preferred first-line treatment. Less pain, less bruising, and a slightly better safety profile make it the superior choice — which is why it is the technique of choice for varicose veins RF ablation in Lucknow at Medanta Hospital.
