Graph showing visual performance during followup. After cross-linking, best spectacle-corrected visual acuity (BSCVA) in patients ≤18 years showed a mean gain of +0.15, +0.19, +0.18 and +0.21 Snellen lines at 12, 24, 36, and 48 months of followup, respectively; in patients between 19 and 26 years showed a mean gain of +0.10, + 0.12, +0.13, and +0.2 Snellen lines at 12, 24, 36, and 48 months followup, respectively; in patients ≥27 years showed a mean gain of +0.07, +0.06, +0.08, and +0.10 Snellen lines at 12, 24, 36 and 48 months of followup, respectively.
