Niu L, et al. - In this prospective non-randomized study involving 37 eyes of 20 patients (mean age was 28.35 ± 4.19 years) who had small incision lenticule extraction (SMILE) (G-S) and 39 eyes of 20 patients (mean age was 27.30 ± 5.46 years) who had Visian Implantable Collamer Lens with a central hole (ICL V4c) implantation (G-V), researchers contrasted one-year visual results and optical quality after femtosecond laser SMILE and ICL V4c implantation for high myopia. According to results, G-S and G-V displayed comparable safety index and efficacy index at the one-year follow-up. Findings suggested that SMILE and ICL V4c implantation present good safety, effectiveness, predictability, and stability in correcting high myopia. During the one-year observation period, optical quality including intraocular scattering was high and relatively stable in both groups.
