In eyes with either zonular dehiscence or weakness, a CTR can prevent marked IOL decentration and tilt and severe anterior capsule contraction, and may lead to prevention of refractive prediction error.
Corneal endothelial cell loss and complications are comparable between eyes with endothelial decompensation after RPK and those after PPK, although VA is worse in eyes after RPK. The outcomes after a first RPK did not differ from those after multiple RPKs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
