Repeated measures ANOVA with AlphaSim correction (>228 voxels) was used for the longitudinal comparison between preoperative and postoperative time points in the Mu- or Mo-IOL group in the visual cortex (BA17, 18, and 19). A two-sample t-test with AlphaSim correction (>228 voxels) was used for the transverse comparison between the Mu- and Mo-IOL groups (P < 0⋅05). A positive peak t-score value indicates an increase, and a negative value indicates a decrease. x, y, z: MNI coordinates of primary peak locations in the Talairach space.

fALFF, fractional amplitudes of low-frequency fluctuations; BA, Brodmann area; MNI, Montreal Neurological Institute; Pre, preoperative; 1 w, 1 week postoperatively; 3 m, 3 months postoperatively; 6 m, 6 months postoperatively; Mo-IOL, monofocal intraocular lens; Mu-IOL, multifocal intraocular lens.
