Post hoc LSD correction; analyses of variance. . F = anterior corneal surface; B = posterior corneal surface; Corneal = total cornea; K1 = flat power of curvature in the center of anterior surface using n = 1.3375 on a ring in 15° around the corneal apex; K2 = steep power of curvature in the center of anterior surface using n = 1.3375 on a ring in 15° around the corneal apex; Rm = average radius of curvature (central radius of curvature in the steep direction/central radius of curvature in the flat direction); Km = average power of curvature using n = 1.3375; LOAs = low order aberrations; TAs = total aberrations. Only r2 and CCT were reported using IOLMaster 500, and others were obtained using Pentacam HR.
