A Comparative Study of Sodium Bicarbonate and Hyaluronidase on Pain Perception, Anesthesia, and Akinesia during Peribulbar Anesthesia for Cataract Surgery.

Background: An ideal anesthetic solution should provide good anesthesia and akinesia with minimal pain on injection.

Aims: The aim of this study is to determine the effect on pain perception and efficacy of sodium bicarbonate over hyaluronidase in the local anesthetic mixture during peribulbar anesthesia.

Settings And Design: A prospective, randomized, double-blind study.
