With its wavelength of 308 nm, the 308 EXCIMER SYSTEM is an effective treatment solution for autoimmune diseases of the skin such as psoriasis and vitiligo. Monochromatic UVB therapy for Psoriasis and Vitiligo. 308 nm UVB Excimer Laser for Psoriasis. Sarah B. Koch, MD. Prior to the publication of this article in the Lancet in 1997, the 308 nm xenon chloride excimer laser was used to treat skin cancers and tattoos, but not psoriasis. 308nm Excimer Laser for Treatment of Fingernail Psoriasis (NAPSI). Therapeutic modalities for localized psoriasis: 308-nm UVB excimer laser versus nontargeted phototherapy.
ABor ZSzabo GIgnacz F 308 nm UVB excimer laser for psoriasis letter. High-dose 308-nm excimer laser for the treatment of psoriasis. The excimer laser can deliver high-intensity ultraviolet B (UVB) energy at 308 nm, a wavelength similar to that used in narrow-band UVB phototherapy. PHAROS excimer lasers are xenon chloride (XeCl) lasers that deliver concentrated, high-dose monochromatic 308nm UVB phototherapy directly to psoriatic and depigmented lesions limiting exposure to surrounding healthy tissue. Unlike conventional UVB systems that emit wavelengths from 290 to 320nm, PHAROS excimer lasers deliver only monochromatic 308nm, an efficacious wavelength for treating psoriasis, vitiligo, atopic dermatitis, and leukoderma.
The authors concluded that with 308nm UVB radiation, it may be possible to clear psoriasis with as little as one treatment, with moderately long remission. Xtrac Excimer 308-nm laser is a laser light source that delivers a specific wavelength (308 nm) of UVB radiation. Compared with narrowband UVB, in the treatment of psoriasis:. 308-nm Laser Phototherapy is an advanced form of UVB phototherapy that delivers targeted, high-dose, monochromatic therapeutic light directly to affected tissue without exposing healthy skin. It may take 12 to 15 treatments to improve psoriasis and cosmetic conditions and 15 to 30 treatments to improve vitiligo.
At Cahaba Dermatology, we offer NB-UVB for psoriasis and vitiligo treatment.
