1940nm varicose vein removal diode laser

The 1940nm diode laser is a modern, highly effective technology for Endovenous Laser Ablation (EVLA), a minimally invasive treatment for varicose veins, valued for its high water absorption, precise thermal effect, and reduced patient pain/recovery time compared to older lasers like 980nm, leading to excellent closure rates and patient satisfaction. This 5th-generation wavelength targets the vein wall effectively, promoting vein closure with lower energy settings, fewer side effects like burns or pigmentation, and minimal post-procedure discomfort, making it a superior, patient-friendly option.

Introduction

How it Works

High Water Absorption: 1940nm light is absorbed strongly by water, causing focused heating within the vein wall, damaging it.
Controlled Energy: Lower power settings (e.g., 4-6W) are sufficient, reducing damage to surrounding tissues.
Vein Closure: Heat causes the vein wall to collapse and seal, and the body reabsorbs the dead tissue.

Key Advantages

Patient Comfort: Less pain during and after the procedure, with lower incidence of bruising or skin discoloration.
Safety & Efficacy: High closure rates (near 100%) with low complications like Endovenous Heat-Induced Thrombosis (EHIT) when anticoagulation is used.
Faster Recovery: Shorter recovery times and quicker return to normal activities.
Modern & Advanced: Considered a 5th-generation EVLA technology, offering significant improvements over older wavelengths.

Comparison to Other Lasers

Superior to 980nm: 1940nm has much higher water absorption than 980nm (which favors hemoglobin), making it more efficient and safer for vein treatment.
Evolution from 1470nm: Offers similar effectiveness to the 1470nm laser but with potentially greater comfort due to its even higher water absorption.

Clinical Use

Treats incompetent saphenous veins (GSV, SSV) and tributary veins.
Often combined with compression stockings and sometimes phlebectomy.
