Excimer laser versus narrow-band UVB (311 nm) in the treatment of psoriasis vulgaris.

Background: The excimer laser is a new therapeutic option in the treatment of psoriasis vulgaris.

Objective: The purpose of this study was to determine the response of psoriasis lesions to the 308-nm excimer laser compared to 311-nm UVB phototherapy.

Methods: In this prospective right/left comparative, open, single-blinded trial, selected psoriasis plaques of 16 patients were treated with the excimer laser whereas the rest of the body was treated with UVB narrow-band phototherapy.
