After a successful trial earlier this year, The Vitiligo Centre Australia has purchased the German Engineered ExSys 308nm light system, a hand-held device that has the same emission spectrum and power output as excimer laser (monochromatic 308nm UVB light). Compared to traditional UVB therapy, doses available are higher, treatment times faster (seconds rather than minutes) and response times much quicker (weeks rather than months)
During the trial, we assessed the treatment on 12 patients (children and adults) with vitiligo affecting areas such as the face, neck, scalp, trunk, limbs hand and feet. The crystal glass cylinders unique to the ExSys 308nm system, allowed superior visibility of the treatment areas, precise delivery of the required dose to the vitiligo lesion, and enabled us to treat difficult areas such as the ears, around the eye and in the groin.
We found that the face. neck, genitals and trunk responded best, particularly in darker skin types. In these areas, with three treatments per week we found 50% of vitiligo patches showed some repigmentation after just 5-6 treatments, and in up to 95% of patches some repigmentation was detected after just 18 treatments. Unfortunately, vitiligo on the hands and fingers did not respond as well.
At your first Excimer light treatment appointment, your skin type will be assessed, and a number of test doses administered to determine the best starting dose for your skin and area of vitiligo. Topical treatment will also be commenced to maximise the response to Excimer light therapy. The dose of UV light delivered and the exposure time is carefully monitored. The dosage will be adjusted according to the skin type reaction. If no adverse reactions are noted, the dosage of UV-light delivered will be increased in small increments at each visit as your treatment progresses.
