Dual Wavelength Surgical Laser for Endovenous (EVLT) Treatment

Dual Wavelength Surgical Laser for Endovenous (EVLT) Treatment

Endovenous Laser Therapy (EVLT) has revolutionized the treatment of diseased veins, offering a minimally invasive alternative to traditional surgical procedures. One of the key advancements in this field is the utilization of dual wavelengths, specifically the combination of 1470nm and 980nm. This dual-wavelength approach capitalizes on the unique properties of each wavelength to enhance the precision, efficiency, and safety of the procedure.

Advantages of 1470nm Wavelength

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.

This characteristic allows for a more precise application of laser radiation into the vein wall, ensuring targeted treatment. Moreover, the process demands less total energy, resulting in lower heat generation. However, it is essential to recognize that the effectiveness of 1470nm can be influenced by the water content of the tissue being treated.

Consideration of Tissue Composition

However, if the water content of the tissue in the nucleus pulposus is not high, the vaporization effect of 1470nm on the nucleus pulposus will be ineffective.

This highlights the importance of considering the specific characteristics of the target tissue when selecting the appropriate wavelength for EVLT. Understanding the tissue composition ensures that the laser therapy is not only precise but also maximally effective.

Dual Wavelength Approach for Optimal EVLT

The dual wavelength stands out as the optimal choice for performing Endovenous Laser Therapy (EVLT) on diseased veins. The 1470nm wavelength has a unique affinity for water within the tissue, meanwhile 980nm enhances hemostasis efficiency, resulting in the highly localized generation of heat. Patients can benefit from a more controlled and efficient procedure, minimizing the risk of damage to surrounding tissues.

1470nm: Precision through Water Absorption

The 1470nm wavelength's unique affinity for water within the tissue allows for meticulous targeting of the vein wall. This precision minimizes the risk of collateral damage to surrounding tissues, contributing to the overall safety of the procedure. The lower energy requirements and reduced heat generation further enhance patient comfort and recovery.

980nm: Enhancing Hemostasis Efficiency

Complementing the advantages of 1470nm, the 980nm wavelength plays a crucial role in enhancing hemostasis efficiency. This wavelength facilitates a highly localized generation of heat, promoting effective coagulation and minimizing bleeding during the procedure. The controlled application of heat ensures that the therapeutic benefits are achieved without compromising the integrity of adjacent tissues.

Patient Benefits and Safety Considerations

The integration of dual wavelengths in EVLT translates into tangible benefits for patients. The controlled and efficient nature of the procedure results in a reduced risk of damage to surrounding tissues. This not only enhances the overall safety profile of the treatment but also contributes to quicker recovery times and improved postoperative outcomes.


In conclusion, the dual wavelength approach in Endovenous Laser Therapy represents a significant advancement in the field of vascular treatment. By combining the precision of the 1470nm wavelength medical laser with the hemostatic efficiency of the 980nm wavelength, practitioners can offer patients a more controlled and effective treatment option. Understanding the tissue-specific considerations and leveraging the synergies between these wavelengths ensures that EVLT is not only technologically advanced but also tailored to the individual needs of the patients. As technology continues to evolve, dual wavelength strategies are likely to play an increasingly central role in optimizing the efficacy and safety of medical interventions.
