Case ReportsTraumatic cataract with a ruptured posterior capsule from a nonpenetrating ocular injury.
An 11-year-old boy had posterior lens capsule rupture resulting from a nonpenetrating (blunt trauma) injury to the eye. A rapidly developing cataract required pars plana lensectomy. This report suggests that posterior capsule rupture may occur secondary to blunt trauma and progressive cataract formation after posterior capsule rupture may require surgery soon after the injury.

A survey of the practice styles and preferences of members of the American Society of Cataract and Refractive Surgery with a United States ZIP code was performed in September 1997. Approximately 29% (1441) of the 5000 questionnaires mailed were returned by the November cut-off date. Three main profile questions were used to cross-tabulate data: age of the ophthalmologist, geographic location, and volume of cataract surgery per month. Current data were compared with data in previous annual surveys.

Randomized Controlled Trial Comparative Study Clinical TrialSublingual lorazepam as premedication in peribulbar anesthesia.
To assess the efficacy of sublingual lorazepam in inducing amnesia when used as a premedication for peribulbar anesthesia. ⋯ Sublingual lorazepam improved patient comfort by inducing amnesia, and in the low dose used in this study, did not adversely affect surgery by undue heavy sedation.
