The changes in uncorrected distance visual acuity (UDVA) and best spectacle-corrected visual acuity (BSCVA) shown as percentages of lines gained/lines lost. Changes in UDVA after 12 months in the CXL-Plus group (a) and in the CXL group (b) and after 24 months in the CXL-Plus group (c) and in the CXL group (d) respectively. Changes in BSCVA after 12 months in the CXL-Plus group (e) and in the CXL group (f) and after 24 months in the CXL-Plus group (g), and in the CXL group (h) respectively. CXL = Corneal cross-linking, CXL-Plus = Central corneal regularization combined with CXL
