AKderm is an irradiation system designed for small areas. One advantage is the direct skin contact which reduces the risk of various source errors such as underdosing due to patient movement or wrong dose calculations.
The irradiation situation is optimized by the direct application of the lamp to the skin and the treatment time is reduced to about 7 minutes.
By restricting the irradiated area to about 25 cm², the phototoxic damage of the surrounding healthy tissue is minimized in comparison with large area PDT lamps. In addition the pain which is almost always observed during treatment with large area lamps is greatl reduced or avoided completely.
One advantage of high power LEDs in comparison to halogen or other thermic lamps lies in the precise emission of the optimal wavelengths for PDT treatments. LEDs also have good energy efficiency and life span.
Photodynamic therapy (PDT) is a non-invasive procedure for the treatment of superficial epithelial skin tumors and their precursors (actinic keratosis, basal cell carcinoma, Morbus Bowen). The local application of a so-called photosensitizer in the form of a cream or plaster and the resulting precisely localized light-sensitivity make PDT a very non-aggressive method with an excellent cosmetic outcome.
The method is based on the selective accumulation of a photo sensitizer in the tumor tissue. If the tissue prepared in this way is irradiated with light of a suitable wavelength, a phototoxic reaction is induced in the tissue, leading to massive cell damage and eventually cell death. Healthy cells mostly remain unaffected by this reaction.
In addition to the patient-friendly ambulant treatment, the great advantage of this method lies in the way it maximizes the protection of the surrounding healthy skin and usually results in scar-free healing. Here AKderm, with its small format allowing precise application, fills a gap in the therapeutic approach to the treatment of light skin cancer.
