Table 1

Preoperative demographics of the study population in eyes undergoing corneal cross-linking for progressive keratoconus.

Preoperative demographics (median (25th and 75th percentile))
Number of eyes	20
Male : Female	14 : 6
Age	26.5 (21.8, 38.0) years
Uncorrected visual acuity (logMAR)	1.00 (0.70, 1.40)
Corrected visual acuity (logMAR)	0.40 (0.10, 0.52)
Manifest spherical equivalent	-2.31 (-6.00, -0.69) D
Manifest cylinder	3.00 (1.25, 5.00) D
Sim K	52.65 (46.00, 55.70) D
