A careful air management strategy successfully prevented pupil block in eyes that developed full air fill. DMEK-only procedures were more likely to require air removal than those combined with cataract surgery, which suggests that decreased zonular flexibility may prevent the air bubble from taking a more spherical shape and more easily allow occlusion of iridotomy.
This study demonstrates the substantial rate of rejection episodes that can be induced by corneal stroma in DALK and suggests that postoperative topical corticosteroids should be continued longer than the study's 7-week median and that young African Americans need higher-dose, longer-duration topical corticosteroids. The association between the side-cut method and rejection risk merits further investigation.
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.
