This study aims to evaluate the safety and efficacy of bilateral peribulbar block for cataract surgery.
Cataract surgery is one of the most commonly performed procedures worldwide, with local anesthesia being the preferred method due to its safety, efficacy, and cost-effectiveness. Peribulbar anaesthesia has gained popularity due to its relative efficacy in generating ocular akinesia and anaesthesia with a reduced risk of consequences such as optic nerve damage and globe perforation.

RECRUITINGDegree of pain
The pain will be evaluated by straightforward questioning using a 3-point scoring method (no pain = 0, discomfort = 1, pain = 2) during the procedure.
Time frame: Intraoperatively
Patient satisfaction
The point in time to satisfactory surgical anesthesia will be assessed on a 5-point Likert scale patient satisfaction (1, extremely dissatisfied; 2, unsatisfied; 3, neutral; 4, satisfied; 5, extremely satisfied)
Time frame: 24 hours postoperatively
Grading of Akinesia
Motor block will be assessed by estimation of globe akinesia in the four quadrants, discriminated by the 4 directions of the gaze: lateral, medial, superior, and inferior. A 3- point scoring method will be chosen, in which 0 = akinesia, 1 = incomplete akinesia, and 2 = natural movement, with a total score ranging from 0-8 for the four muscles.
Time frame: Intraoperatively
Incidence of adverse events
Incidence of adverse events such as coughing, vomiting, hypotension, bradycardia, tachycardia, arrhythmias, proptosis, globe puncture, or retrobulbar hemorrhage will be recorded.
Time frame: 24 hours postoperatively
