Graph showing visual performance during followup. After cross-linking, uncorrected visual acuity (UCVA) in patients ≤18 years showed a mean gain of +0.14, +0.17, +0.16, and +0.2 Snellen lines at 12, 24, 36, and 48 months of follow-up, respectively; in patients between 19 and 26 years showed a mean gain of +0.13, +0.16, +0.12, and +0.14 Snellen lines at 12, 24, 36, and 48 months of followup, respectively; and in patients ≥27 years showed a mean gain of +0.08, +0.09, +0.12, and +0.12 Snellen lines at 12, 24, 36, and 48 months followup, respectively.
