Why 1470nm and 980nm ?810-980nm
are absorbed in the first
instance by hemoglobine (HbO2) whereas
longer wavelenth like 1470nm are dominantly absorbed by
intracellular
water
Example
1: Absorption coefficient for 1470nm approximatelly 40 times higher than 980
Example
2: Absorption coefficient for 1470nm approximatelly
400 times higher than 810nm
Better

Leonardo Dual 45 in dermatology
A variety of vascular lesions can be treated using the external
handpiece
including spider veins, telangiectasias and hemangiomas found on the legs,
face
, neck
and
chest using 980nm which
has a absorption peak in the near infra red The result of epidermal cooling andhigher laser
fluences increases efficacy, allows deeper laser penetration, and minimizes treatment pain for larger vessels.
Exact position of the individual laser pulse signals (optimal closure rate)Slide17

Precise
Targeting
of
Spiders
The light of a 980 nm wavelength ensures precise targeting for spider veins due to its:
•
Effective penetration depth• Optimal absorption by hemoglobin • Ideal absorption by
water
• Minimal melanin absorption when compared to other lasers The Benefit:
• Safer and more effective treatment• Treatment of darker skin types Slide18
Presentation by Dr. Julio Ferreira„Laser in
dermatology „___________________________________________1)(Combination-therapy
) the laser
treatment can be combined with the classic sclerosation
therapy
. E.g. wider
areas
with heavily braching
lesions can be primary served by sclerosation and therapy resistant
lesions
can be definetelly cured with the pulsed
diode laser. Avoid
side effects like blisters
and scars by
carefull selection of the
energy ands use it only on non tanned patients
.2)Complicated venous or
mixed malformations can be
adressed
by
interstitial
