Comparisons of postoperative BCDVA and the OQAS optical metrics among the 4 groups. (A): Postoperative best corrected distance visual acuity (BCDVA). (B): Postoperative predicted visual acuity (PVA) at contrasts of 100%. (C): Postoperative PVA at contrasts of 20%. (D): Postoperative PVA at contrasts of 9%. (E): Postoperative strehl ratio (SR). (F): Postoperative objective scattering index (OSI). (G): Postoperative modulation transfer function (MTF) cut-off frequency. A, B, C, D, E, and F were presented in box and whiskers plots as they were nonnormally distributed; G was presented in plots with mean and error bar as it was normally distributed. *P < 0.05, **P ≤ 0.01; ***P ≤ 0.001
