Observational Study
The Independent Effect of Various Cross-Linking Treatment Modalities on Treatment Effectiveness in Keratoconus.
To investigate the 1-year outcomes of using various corneal cross-linking (CXL) techniques for treating keratoconus. ⋯ TE-CXL, the use of Meran riboflavin, and applying the accelerated irradiation protocol appeared to be associated with reduced efficacy regarding controlling keratoconus progression. One-third of cases treated using TE-CXL required re-treatment.

To evaluate the effectiveness of repeated corneal collagen cross-linking (CXL) in eyes with progressive keratoconus after primary CXL. ⋯ Repeated CXL seems to be effective in stabilizing keratoconus progression after failure of primary CXL. Patients should be followed up at least for 2 years after primary CXL.
