Rate of Corneal Collagen Crosslinking Redo in Private Practice: Risk Factors and Safety
PURPOSE The aim of this study was to report 2 cases with topographic keratoconus progression despite stability for a long-term period after corneal collagen crosslinking (CXL). METHODS This is a case report. RESULTS Two patients with progressive keratoconus underwent CXL treatment. Four and 5 years postoperatively, a topographic examination revealed an increase in the keratometric values indicating keratoconus progression. CONCLUSIONS Post-CXL, topographic keratoconus progression may occur several years after, despite stability for a long-term period.
