How the laser works
- Lasers with a wavelength of 980 nm are used to deliver the laser energy to the wall of the vein using an optical fibre with a very small calibre (600 or 200 microns).
- The energy transmitted by the optical fibre heats and destroys the wall of the vein.
- Unlike the surgical method, Endovenous Laser Treatment does not extract the vein, but destroys it in situ. This procedure is less traumatic. After the laser treatment, scar tissue is formed on the vein, which becomes fibrous and eventually disappears.
- The technique is almost painless, because targeted local anaesthetic can be administered very efficiently (tumescence).
