DALK-operated patients in this study showed similar graft survival, fewer postoperative complications, and equivalent refractive outcomes. No significant difference in the mean BCVA was noted between DALK and PK cases.
Systemic immunosuppression in patients with high-risk keratoplasty seems to improve graft survival with a median follow-up duration of 5 years and is tolerated by most patients. Despite rejection episodes occurring in 40% of grafts, these were mostly reversible.
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.
