Cross linking for keratoconus - clinical results comparing epithelium removal versus no removal
Acta Ophthalmologica, 08/09/2012
Caporossi A et al. – Epi–off CXL showed a constant improvement of functional data while the epi–on procedure showed a relative instability with a regression of functional outcomes returning to baseline at 24 months of follow–up. In patients with progressive keratoconus under 26 years with corneal thickness over 400 microns epi–off cross–linking should be the first choice therapy. According to actual limitations epi–on procedure should be reserved in patients over 26 years with low KC progression or in patients with thinnest point under 400 microns.
