Pre- and postcrosslinking data for treated eyes.

Parameter	Pre-CXL	Post-CXL	𝑃 value
BSCVA (logMAR)	0.24 ± 0.19	0.21 ± 0.13	0.89
MRSE (dioptres)	−5.66 ± 3.47	−4.71 ± 3.11 D	0.71
𝐾1 (dioptres)	46.34 ± 3.13 D	45.67 ± 3.31 D	0.03
𝐾2 (dioptres)	50.06 ± 3.84 D	49.34 ± 3.18 D	0.005
Topometric astigmatism (dioptres)	3.50 ± 1.36 D	3.25 ± 1.79 D	0.51

BSCVA: best spectacle corrected visual acuity, logMAR: logarithm of the minimum angle of resolution, MRSE: manifest refraction spherical equivalent, 𝐾1: mean simulated keratometry value in the flattest meridian, and 𝐾2: mean simulated keratometry value in the steepest meridian.
