Comparing two treatment methods of progressive keratoconus



Keratoconus is a progressive eye disorder in which the cornea becomes thin and irregular in shape. Corneal collagen cross-linking (CXL) is the standard care of progressive keratoconus to stabilise the disease process. In this meta-analysis, comparative studies between iontophoresis-assisted CXL (I-CXL) and standard epithelium-off CXL (S-CXL) were analysed. As evidenced by the available literature, I-CXL can significantly reduce complications with a better safety profile, especially in eyes with higher baseline Kmax.
