Role of hyaluronidase in diplopia after peribulbar anesthesia for cataract surgery.

Objective: To determine the protective action of hyaluronidase on peribulbar anesthesia-related diplopia in patients undergoing cataract surgery.

Design: Single-center observational case series.

Participants: All patients undergoing elective phacoemulsification and intraocular lens implantation under peribulbar anesthesia between February 2001 and January 2003.
