  1. The parameters are presented as mean (lower quartile, upper quartile) and number (percent), UCVA stands for uncorrected visual acuity, BCVA stands for best corrected visual acuity, IOP stands for intraocular pressure, SE stands for spherical equivalent, RF stands for corneal flat axil radius of curvature, RS stands for corneal steep axil radius of curvature, RM stands for mean corneal radius of curvature, ECD stands for endothelial cell density. P * stands for P value after adjusting for age and gender
