Refractive outcomes over time (Mean ± SD) and correlation with cap morphology.

SE = spherical equivalent; UDVA = uncorrected distance visual acuity; CDVA = corrected distance visual acuity; CcT = central cap thickness; U = a gross index of uniformity, the standard deviation of the cap thickness of total 33 points; *Statistically significant correlation was found; rs = Spearman correlation coefficient.
