About this study

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.

Treatment and study plan

Bilateral peribulbar block

Other

Patients undergoing bilateral peribulbar anesthesia for cataract surgery.

Primary outcomes

  1. Degree of pain

    Time frame: Intraoperatively

    The pain will be evaluated by straightforward questioning using a 3-point scoring method (no pain = 0, discomfort = 1, pain = 2) during the procedure.

Secondary outcomes

  1. Patient satisfaction

    Time frame: 24 hours postoperatively

    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)

  2. Grading of Akinesia

    Time frame: Intraoperatively

    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.

  3. Incidence of adverse events

    Time frame: 24 hours postoperatively

    Incidence of adverse events such as coughing, vomiting, hypotension, bradycardia, tachycardia, arrhythmias, proptosis, globe puncture, or retrobulbar hemorrhage will be recorded.
