Clinical efficacy of femtosecond laser for myopia: A systematic review protocol of randomized controlled trial

BACKGROUND: Femtosecond laser (FL) is an effective method to treat patients with myopia, but its relative efficacy and safety is still unclear. Thus, this study will be conducted to assess the efficacy and safety of FL for myopia systematically. METHODS: This study will systematically retrieve the following electronic databases up to the present: Cochrane Library, PubMed, EMBASE, Web of Science, PsycINFO, Allied and Complementary Medicine Database, Chinese Biomedical Literature Database, Wanfang, VIP, and China National Knowledge Infrastructure. All electronic databases will be searched without any limitations of language and publication status. RevMan 5.3 software will be utilized for statistical analysis. RESULTS: We will summarize the targeted results evaluating the efficacy and safety of FL for patients with myopia. CONCLUSIONS: This study will provide a comprehensive evidence summary on FL for patients with myopia. PROSPERO registration number: PROSPERO CRD42019148659.
