Corneal sensation and dry-eye signs and symptoms improved at all intervals between 1 week and 6 months. The loss of corneal sensation and presence of dry-eye syndrome were greater in eyes with a narrow hinge flap than in eyes with a wider hinge flap.
The results of the randomized trial indicate that the fixed combination dorzolamide-timolol (Cosopt) was as effective as its components in controlling IOP, confirming results seen in phase 3 clinical trials. However, in the replacement study, utilization of the combination drug offered a statistically significant additional IOP reduction (P < 0.0001), which duplicates results from previous replacement studies.
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.
