ABSTRACT

Introduction: laser treatment for onychomycosis has been described as an easy to perform and safe method. Objective: to evaluate the efficacy and safety of 1064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) Q-switched laser for the treatment of onychomycosis. Method: This retrospective study included 700 patients with suggestive onychoscopy. KOH direct examination confirmed diagnosis of onychomycosis of patients who were treated with 1064-nm Nd:YAG Q-switched laser from April 2012 to December 2023. Results: Most of the patients required only 1 session (86%) and showed clinical response at 6 months while 14% required a second laser session. Clinical and mycological response was seen in 100% at 12 months. There were no documented side effects. Conclusions: Our long-term experience confirmed the efficacy and safety of Nd:YAG Q-switched laser treatment of onychomycosis.
