Abstract: Corneal collagen-crosslinking (CXL) has been widely investigated in the adult population. There is still little available in the literature, however, on the effects of CXL in children. A review of the literature on CXL in the pediatric population is presented here, with a particular emphasis on the refractive effects. Although several studies demonstrate promising results, most studies have small sample sizes with relatively short follow-up periods. Further investigation on the effects of CXL in the pediatric population is required to better understand long-term effects.

Abstract: In this review, recent studies regarding riboflavin-ultraviolet A (UVA) collagen cross-linking for the treatment of acanthamoeba keratitis (AK) were reviewed. English written studies about acanthamoeba, keratitis, riboflavin and collagen cross-linking were retrieved from PubMed search engine (www.ncbi.nlm.nih.gov/pubmed). Although there were significant numbers of cases reporting the effectiveness of riboflavin-UVA collagen cross-linking in AK, experimental studies (in vivo and in vitro) failed to verify amoebicidal or cysticidal effect of riboflavin-UVA collagen cross-linking. In conclusion, the efficacy of riboflavin-UVA collagen cross-linking for the treatment of AK is still debatable. It is necessary to conduct a prospective case-control study for clear guidance for clinicians.
