Topical versus sub-Tenon's anesthesia without sedation in cataract surgery

Abstract

Patients having cataract surgery under topical anesthesia had more intraoperative and postoperative discomfort than patients receiving sub-Tenon's anesthesia. However, patients having topical anesthesia reported less pain during its administration and had fewer complications. Both anesthesia methods provided high levels of pain control without additional sedation.
