Abstract

Erbium: YAG (Er:YAG) laser with RecoSMA technology. This laser emits thousands of microbeams of energy causing superficial epidermal ablation and a separation of dermal fibers due to a mechanical-acoustic and resonance effect. The aim of this study is to evaluate the clinical efficacy of Erbium: YAG (Er:YAG) laser with RecoSMA in the treatment of stable psoriasis vulgaris lesions. A questionnaire completed by 112 patients enrolled in the study. Photographs taken before each session, the analysis of the dynamics index PASI and histological studies were analyzed to visually monitor the clinical progress. The analyses were carried out with the help of computer software. The results after treatment of average number of sessions per course showed the complete clinical remission of the skin lesions in over 87% of the patients treated. The Er:YAG laser and RecoSMA have demonstrated the high effectiveness of the laser method of treating skin manifestations of the disease and improving the quality of life of patients.

Keywords: Er:YAG; PASI index; RecoSMA technology; laser; mechanical-acoustic effect; psoriasis vulgaris; space-modulated ablation.
