Investigators retrospectively evaluated the four-year outcomes of corneal cross-linking (CXL) for progressive keratoconus among 300 patients, stratified according to age. CXL was effective in stabilizing progression in all age groups, but patients between ages 18 and 39 achieved better functional and morphological results. All age groups – under 18, 18–9, 30–39, and over 40 years – experienced a significant improvement in BCVA. Additionally, patients demonstrated a significant decrease in spherical equivalent and a decrease in topographic parameters. Ophthalmology, May 2012
