KTP laser (532 nm)
The KTP laser works with light of 532 nm wavelength, which is absorbed by the red blood pigment. We use it for vascular changes: dilated small vessels on the face, spider naevi, haemangiomas, port-wine stains and spider veins following sclerotherapy.
Overview
The KTP laser works with a wavelength of 532 nm and is used to treat vascular changes. Its light lies in a range that almost matches the absorption behaviour of oxyhaemoglobin, the oxygen-rich red blood pigment. It is therefore taken up preferentially in the blood vessels. In our practice we use a KTP laser for this [PLATZHALTER: Gerätemodell bestätigen].
The high pulse energies are matched to the thermal relaxation time of the vessels, that is, to the time in which a vessel gives off the heat it has absorbed. In this way the heat stays in the vessel while the surrounding tissue is affected as little as possible. Side effects such as scars, thermal damage or purpura (a temporary bluish discolouration) are comparatively rare; they cannot be ruled out.
Typical fields of use are dilated small vessels on the face, spider naevi, haemangiomas and port-wine stains, as well as spider veins following prior sclerotherapy. Which vascular laser system is suitable in the individual case we decide during the examination; the detailed descriptions can be found on the linked pages.
