The paper discusses the active delivery of a drug (methylene blue solution) through the Er:YLF-laser-perforated nail plate using pulsed radiation of microsecond Yb,Er:Glass laser. Different methods of laser impact on liquid drug are considered: by focused and diverging laser beam. It was established that both discussed methods can provide sufficient dose of the drug for the treatment of onychomycosis.
