Evaluation of local anesthesia techniques for small incision cataract surgery

Abstract

Although less discomfort/pain occurred during surgery with RBA, patients preferred STA and TA primarily because of the inconvenience or pain of the retrobulbar injection. Although medical sedation was not used in this study, the pain/discomfort ratio from surgery was not greater than in studies using intravenous sedation, indicating that the use of medical sedation should be re-evaluated.
