Application
1590 99 002_1 - 21. February 2011 55
The MeDioStar is switched to the mode with the desired FLUENCE.
At the start of the operation, the cold probe of the handpiece is shortly placed on the first point to
be treated. Then, the handpiece is moved by the spot size so that the laser tip comes to the pre-
cooled area. Afterwards, the laser emission is started by pressing the foot switch and the handpiece
is further moved by the spot in the cycle of the set SPEED in direction to the skin cooling probe.
Practically, the handpiece should be kept in contact with the skin and should not always be put on
anew. Due to the ultrasound gel the point can easily be seen at which the spot must be placed for
the next line. A slight overlapping is necessary so that no hair line is left out because the cooling
probe, which marks the track in the ultrasound gel, is a little bit larger than the active laser spot.
In the mode contrary to the procedure described above -
cooled and than the handpiece is moved rapidly over an area of about 10 x 10 cm² in the cycle of
the set speed. In doing so the handpiece has to be held in a way, that the laser spot moves over the
pre-cooled line and the cold probe pre-cools the next line simultaneously. The handpiece can be
moved than in a serpentine pattern back and foth. Several passes must be performed, whereas the
direction is changed (e.g. from top-down to left-right).
Make sure that the cold probe of the skin cooling is kept in contact with the skin during the
treatment to guarantee the pre-cooling of the epidermis. It is advantageous for epilation to apply a
slight pressure by the handpiece onto the skin. Thus, the distance to the hair root is reduced and the
effectiveness of the treatment is increased.
If the area is completely lasered, the device must be switched to the
mode.
Only if a skin reaction cannot be seen after 10 minutes the energy density (FLUENCE) can be
increased gradually (test on a new area). In the
mode the number of passes must be
increased step by step.
6.4.8 Treatment
Once the treatment area has been prepared, the area can be marked by using a white pencil (e.g.
Kajal). This ensures that the treatment area will be lased evenly.
In the
mode areas of about 10 x 10 cm² are to be marked and then scanned
systematically in several passes.
The FLUENCE that was well tolerated in the test treatment is to be set in the real operation. Then,
the area is scanned as described above and the handpiece is always moved towards the skin cooling.
The simplest method to keep the tip also clean during the treatment is the use of a slightly
moistened cloth after having lased one line. But if a crack can be heard when treating dark, dense
hair, one hair rest is mostly on the tip. The tip must be cleaned immediately. If the laser treatment is
continued nevertheless, the hair will burn in and can possibly not be removed by wiping it off.
If large areas need to be lased, the skin surface should preferably be treated in longitudinal direction
(apart from the mode) in order to keep effects of physical pain building up at a
minimum level particularly for dark, thick and dense hair (use EMLA if necessary).
Once the area is completed, the laser must be switched to STANDBY mode.
6.4.9 Post-op treatment
Immediately after completion of lasing, the skin should be cooled over an extended period,
particularly for dark hair and dark skin. Continuous cooling can considerably reduce the side effects!
This can easily be done with CoolPacks which the patient can apply as appropriate.
An anti-inflammatory ointment may be applied following sufficient cooling of the skin. In the event
of overtreatment, a topical antibiotic is indicated and the monitoring of healing is absolutely
necessary.
