The purpose of this review is to determine the indications and efficacy of the surgery that promotes new covalent bonds between the collagen fibers of the cornea, known as Cross-Linking (CXL), as well as to clarify its objectives. Keratoconus is a bilateral, asymmetric ectasic disease of the cornea that mainly courses with steepening and progressive thinning, and usually begins in the second decade of life. The primary use of CXL has been in discontinuing the progression of keratoconus. Although known […]

Purpose: To determine the safety and efficacy of corneal collagen cross-linking (CXL) for progressive keratoconus in patients aged between 9 and 14 years old. Methods: Sixteen eyes of 11 patients (8 male and 3 female) with progressive keratoconus underwent epithelium-off CXL according to the standard Dresden protocol. Mean follow-up was 26 months (range, 12 to 60 months). Pre- and postoperative examinations included: uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), corneal topography, tonometry, refraction, corneal pachymetry, and endothelium cell […]

In middle of 90th decade, corneal collagen crosslinking photo-induced by riboflavin was considered as a new therapeutical modality in the treatment of keratoconus. Since then, the clinical effect of this procedure in laboratorial environment and clinical assays had been studied. In this article, we revise the literature already published until the moment in order to display on the procedure and its effects.
