Notes: The two-sample t-test with FDR correction (>20 voxels) was used for the comparison between the control and cataract groups. The repeated measures analysis of variance test with FDR correction (>200 voxels) was used for the comparison between preoperative and postoperative time points in the cataract group. A positive peak t-score value indicates an increase, and a negative value indicates a decrease. GM, grey matter; BA, Brodmann area; MNI, Montreal Neurological Institute. Pre, preoperative; Post-1 w, 1 week postoperatively; Post-3 m, 3 months postoperatively; Post-6 m, 6 months postoperatively; x, y, z: MNI coordinates of primary peak locations in the Talairach space; R, right; L, left; Frontal. Inf. Orb, inferior orbitofrontal cortex; Frontal. Med. Orb, medial orbitofrontal cortex.
