6.5.5 Test treatment
If the patient decides in favor of a laser treatment after getting the information from the physician, a
test treatment should be performed afterwards in any case.
Due the high number of different vessel diameters the practically optimum fluence can only be
found empirically by treating test areas and must be defined anew for each area that has another
vessel diameter (color/structure change).
CAUTION
The higher fluence required for the treatment of dilated vessels and the stronger
absorption due to the size of the vessel diameter can cause more intensive side effects
(e.g. compared to hair removal).
Therefore, a sufficient cooling before and after the treatment is very important to
minimize the side effects!
After preparing the treatment area, the test area to be treated is pre-cooled during some seconds by
using a cool pack (ca. 4-8°C). Afterwards the cooling probe of the handpiece is moved backwards
and forwards in longitudinal direction over the vessel to be treated without an active laser.
The test fluence for skin type III must be set lower than for light skin, the pulse duration as short as
possible for the set fluence for smaller vessels and longer for larger vessels and skin type III. The
treatment speed principally used at the beginning is set to 0.5 Hz (SPEED). This setting allows to
assess the situation after only one pulse because it is possible to deactivate the foot switch after one
pulse.
Moreover, the lower the treatment speed the longer the pre-cooling time for the next area to be
treated.
WARNING
Laser radiation can cause serious damage to the eye.
Everyone present in the laser room during a treatment session must wear laser safety
goggles according to the instructions given in chapter 3
!
The set fluence must be controlled before and during the treatment!
The MeDioStar is switched to the mode with the desired fluence.
Tip
Contrary to epilation treatments, pressure is NOT applied by the handpiece. .
It is recommended to keep a distance of about 1mm beween laser probe and skin. At the
same time the cold probe of the skin cooling has to be in contact to the skin (please tilt
the handpiece a little bit).
2-3 pulses are applied to the area to be tested; the laser tip is moved towards the skin cooling.
Afterwards, the area treated is assessed.
If the vessel has faded (more typical for smaller vessels) or becomes darker (more typical for larger
vessels) the fluence will be kept and spot by spot is placed along the vessel.
Immediately after the laser treatment, the cooling probe is used to post-cool the area for some
seconds.
If a reaction cannot be observed, wait some minutes to see if an inflammation reaction develops. In
this time it is also possible to test another vessel size in the same procedure.
The larger the vessel the lower the fluence required normally.
If even after waiting a reaction cannot be seen, the NEW (!) test area is again pre-cooled by using
the cooling probe and then it is lasered in an overlapping manner or the same area twice before the
fluence is increased, if required. The risk of side effects is less in case of overlapping than for a too
high fluence!
