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.
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.
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.
