Randomized Controlled Trial
Evaluating the effectiveness of localized sub-Tenon's anesthesia in 23-gauge vitreoretinal surgery.
To evaluate the effectiveness of localized sub-Tenon's anesthesia for pain control during 23-gauge vitreoretinal surgery. ⋯ Localized sub-Tenon's anesthesia is as effective as retrobulbar anesthesia in many steps of vitreoretinal surgery for providing pain control. It can be considered an alternative form of local anesthesia.
