In this letter to the editor the authors state that sub-tenons anesthesia could replace peribulbar needle injections when combined surgery for cataract and glaucoma has to be performed. They use after two drops of lidocaine 4% and injection of 1.5 ml, 30 ?g of mepivacaine into the sub-tenons space near the superior rectus muscle. They reviewed the charts of the first 50 patients comparing the intraoperative and postoperative complications to those who had been given a peribulbar needle anesthesia. The intraoperative complications did not differ. They therefore feel that sub-Tenon's anesthesia can replace peribulbar injections.
