^aNormally distributed continuous data were described by mean (standard deviation)
^bNonnormally distributed continuous data were described as the median (interquartile range)
Mon = monofocal IOLs; SegRef = segmental refractive IOLs; Dif = diffractive IOLs; EDoF = extended depth of focus IOLs; UCVA = uncorrected visual acuity; IOP = intraocular pressure; AL = axial lengths
UCVA was shown in logMAR (logarithm of the minimum angle of resolution)
