SEQ spherical equivalent, BSCVA best spectacle-corrected visual acuity, CCT central corneal thickness, MCT minimal corneal thickness, Kmax maximum keratometry.

^aStudent’s t test and chi-square.

^bAdjusted for age, baseline BSCVA, corneal astigmatism, baseline kmax and coma with regression analysis.
