Analysis of 69 cases of adverse events associated with laser treatments

Background: During the past two decades, laser treatments have been increasingly performed by various personnel in Korea. However, as a result, adverse events related to laser treatments have also increased. Objective: This study aimed to characterize cutaneous adverse events associated with laser treatments in Korea and to consider feasible ways to minimize possible laser-associated adverse events. Methods: Adverse event reports after laser treatments were collected from the members of the Korean Dermatological Association. A retrospective analysis of clinical data was performed regarding the pre-treatment lesion, specific laser type applied, personnel who performed the procedure, and consequences in terms of treatment-related complications. Results: A total of 69 reported cases of adverse events associated with laser treatment were collected. The most frequently reported adverse event was postinflammatory dyspigmentation, followed by secondarily induced dermatological disease, treatment-inflicted burn, and residual scar. Conclusion: Both expected and unexpected adverse events occur after laser treatments. Most adverse events are not serious, but proper dermatological attention should be given to avoid complications. It should be noted that the safest and the most successful laser treatment can be provided only by qualified personnel.
