Efficacy and safety of dexmedetomidine as an additive to local anesthetics in peribulbar block for cataract surgery.

Background And Objectives: We evaluated the effect of adding dexmedetomidine to lidocaine and bupivacaine for peribulbar block in two different doses. The primary endpoints were the onset and duration of corneal anesthesia, globe akinesia, and duration of analgesia.

Materials And Methods: A randomized controlled clinical trial was conducted on 90 ASA I-II patients scheduled for elective cataract surgery under peribulbar anesthesia.
