Abstract:
Femtosecond laser small-incision lenticule extraction(SMILE)and femtosecond laser-assisted in situ keratomileusis(FS-LASIK)are the mainstream corneal refractive surgeries at present. With the emergence of optical coherence tomography angiography(OCTA), an automatic and precise analytical technique, it has been widely applied in the evaluation of retinal and choroidal diseases, and has emerged as a novel tool for exploring the impacts of corneal refractive surgery on posterior ocular segment microcirculation. This article systematically reviews the characteristics of fundus microcirculation changes after SMILE and FS-LASIK surgeries, compares the differences in microcirculatory alterations between the two procedures, analyzes the limitations of existing studies, and discusses future research directions. It provides a theoretical basis for evaluating the safety of refractive surgery and selecting individualized surgical approaches.
