Cylinder (D)	−0.45 ± 0.18 (−0.75 to −0.25)	−0.49 ± 0.27 (−1.00 to −0.00)
SE	−3.62 ± 7.73 (−21.37 to +16.25)	−3.76 ± 6.25 (−22.88 to +3.50)

Student’s t-test; Mann–Whitney test. UDVA: uncorrected distance visual acuity; CDVA: corrected distance visual acuity; SE: spherical equivalent; D: diopter; LogMAR: logarithm of the minimum angle of resolution. Corresponding p values for the comparison between groups are shown for each parameter evaluated.
