aCount data were described as absolute numbers (percentages), and comparison between groups was analyzed using the Chi-square test; bThe measurement data that did not meet the normal distribution were described by the median (interquartile range), and the Kruskal-Wallis H test was used for comparison between groups; cThe measurement data that meet the normal distribution were described by mean (SD), and comparison between groups was performed by completely randomized analysis of variance. IOLs: Intraocular lens; logMAR: Logarithm of the minimum angle of resolution; UCVA: Uncorrected distance visual acuity; Km: Mean keratometry; Mon IOLs: Monofocal intraocular lens; SegRef IOLs: Segmental refractive intraocular lens; Dif IOLs: Diffractive intraocular lens; EDoF IOLs: Extended-depth-of-focus intraocular lens.
