If you have searched for varicose vein surgery in India, you will have encountered confusing acronyms: EVLA, EVLT, RFA, MOCA, VenaSeal, ClariVein, foam sclerotherapy, vein stripping. This page explains every varicose vein surgery name in plain language, with a comparison table to help you understand which one your doctor may recommend.
1. EVLA / EVLT — Endovenous Laser Ablation
The most widely used modern technique. A thin laser fibre is passed inside the diseased vein under ultrasound guidance and energised, sealing the vein from inside. Done under local anaesthesia. Same-day discharge. 95%+ success rate at 5 years.
2. RFA — Radiofrequency Ablation
Like EVLA but uses radiofrequency heat instead of laser. Equivalent results, slightly less post-procedure bruising. Brand name in India: ClosureFast.
3. MOCA — Mechano-Chemical Ablation (ClariVein)
A rotating wire mechanically irritates the vein wall while a sclerosant chemical is delivered simultaneously. Non-thermal — no risk of nerve burn. Ideal for veins close to nerves (small saphenous, below-knee great saphenous).
4. VenaSeal — Cyanoacrylate Medical Glue
A medical adhesive (similar to super-glue) is delivered into the vein, instantly closing it. No tumescent anaesthesia, no compression stockings needed afterwards. Most patient-friendly option, slightly higher cost.
5. Foam Sclerotherapy
A foaming sclerosant medicine is injected into smaller varicose branches and tributaries. Usually used in combination with EVLA / RFA, not as standalone for large trunk veins.
6. Open Surgery — High Ligation & Stripping (Now Obsolete)
The traditional surgery where the vein was tied off at the groin and physically pulled out from below. Required general anaesthesia, hospitalisation, multiple incisions, weeks of recovery. Now considered obsolete in any centre with modern equipment.

Frequently Asked Questions
Which is the best varicose vein surgery?
There is no single "best" — the right technique depends on vein anatomy, location, patient preference and budget. EVLA and RFA are gold standard for trunk veins; MOCA is preferred near nerves; glue is the most patient-friendly. A skilled vein specialist will combine techniques.
Is laser surgery for varicose veins safe?
Yes — EVLA has been performed worldwide for over 25 years with an excellent safety record. Major complications occur in less than 0.5% of cases when done by experienced operators.
How long does varicose vein laser surgery take?
The procedure itself takes 30–60 minutes per leg. Including admission, prep and observation, total time at the clinic is about 3–4 hours.
Do I need to be hospitalised?
No. All modern techniques (EVLA, RFA, MOCA, glue) are walk-in walk-out under local anaesthesia. You can go home within 2 hours of the procedure.
