    Abstract:
    BACKGROUND: Several lasers have been used for the treatment of xanthelasma palpebrarum (XP), such as Q-switched neodymium:yttrium aluminum garnet (QSNd:YAG) and erbium:yttrium aluminum garnet (Er:YAG) laser. Up to now, a comparative study among these laser options in the treatment of XP has not been reported. OBJECTIVE: The aim of this study was to compare the clinical efficacy and response rates of QSNd:YAG and Er:YAG in the treatment of XP. METHODS: Sixty patients with a total of 102 XP lesions were randomly and equally divided into two groups. The first group was treated with QSNd:YAG at a fluence of 10 joule/cm2, 10 Hz and 2 mm spot size, and the second group was treated with Er:YAG at 200-300 millijoule, 4 Hz and 2 mm spot size. RESULTS: In the Er:YAG group, the percentage of patients who required 3 or 4 sessions and wound healing time were higher compared to those of the QSNd:YAG group. Furthermore, the percentage of patients who had an improvement score of 4 was higher in the Er:YAG than that in the QSNd:YAG group. CONCLUSION: Er:YAG is an efficient, successful and minimally invasive method without long-lasting adverse effects.
