Laser Treatments for psoriasis
About 7.5 million Americans suffer from psoriasis, but a new Food and Drug Administration-approved laser treatment could offer most patients effective relief. Among the various option for treating psoriasis Laser treatment is also a best option for treating psoriasis. Excimer lasers deliver ultraviolet light to localized areas of the skin. Lasers offer a unique treatment option called “targeted phototherapy.” This means that the light from the laser can target the psoriasis and not touch the surrounding skin. Excimer and pulsed dye laser treatment medically necessary for persons with mild-to-moderate localized plaque psoriasis affecting 10 % or less of their body area who have failed to adequately respond to 3 or more months of topical treatments. This treatment uses intense, focused doses of laser light to help control areas of mild to moderate psoriasis without harming healthy skin around them. One of the biggest benefits of this laser is it only treats the affected areas and doesn't damage surrounding healthy skin.
Tools for Laser Treatment
The tools used in laser treatment are special lasers called 308nm excimer lasers. This type of laser is specially designed to produce ultraviolet radiation at a very specific wavelength -- 308 nanometers. This wavelength of ultraviolet light is highly effective at treating psoriasis. A nearly identical wavelength of light, 311nm is referred to as narrow band UVB (NB-UVB) but is only available using special fluorescent light bulbs in the aforementioned cabinets or booths. Excimer laser gives us the benefits of NB-UVB with the small treatment areas typically ascribed to laser treatments such as a particularly stubborn plaque of psoriasis on the elbow or knee.
The treatments are painless and safe. Patients start to see results usually after the 3rd or 4th treatment. After their Psoriasis is improved, many patients have a period of "remission", where their disease stays away for several months. And it is especially exciting to patients who have not worn shorts or bathing suits in years because they were too embarrassed to let anyone see their skin. In the Laser treatment the light treats only the psoriasis, a strong dose of light can be used. This strong dose can penetrate deeper into the psoriasis. This offers many people an effective way to treat a stubborn patch of psoriasis, such as can develop on the scalp, feet, or hands. The new one hand-held laser, which fires concentrated ultraviolet light rays directly on to the skin, can also be used to treat the skin disorders eczema and vitiligo.
How much Time this Treatment take
This type of treatment requires fewer treatment sessions than other types of phototherapy. If the psoriasis responds to laser treatment, between 4 and 10 treatment sessions typically clear the targeted psoriasis. This will vary with the type of laser and the psoriasis.
How laser treatment is taken?
Laser treatments for psoriasis use one of two types of lasers: a pulsed dye laser (PDL) or an excimer laser. Excimer laser treatments are performed in the dermatologist's office. Each session takes only a few minutes. During the treatment, the doctor aims the laser directly at patches of psoriasis.
