The use of fentanyl as an adjuvant to local anesthetic mixture in many regional blocks. It was effective when used in peribulbar block in cataract and vitreoretinal surgeries. Our study will assess its efficacy in abolishing pain during muscle traction which is usually a complain for many patients a reason to use systemic opioid intra operatively or even general anesthesia
