Primary Outcomes of Accelerated Epithelium-Off Corneal Cross-Linking in Progressive Keratoconus in Children: A 1-Year Prospective Study.

We considered keratoconus to be progressive when K max increased by ≥1.0 D or pachymetry of the thinnest location decreased by ≥5%, on two consecutive corneal tomographic examinations [ 16 ] taking into consideration the inversely correlated severity of keratoconus with age [ 17 ] and highly significant risk of performing keratoplasty with age< 18 years at presentation [ 18 ].
