[Episcleral single injection anesthesia in the caruncle for cataract surgery: report of 350 cases]

Episcleral single injection anesthesia in the caruncle ovoïds the rare but potentially dangerous complications and incidents of classic local anesthesia. Excellent motor and sensory block is obtained with a single injection in the anatomic marks are well defined. We have practiced this technique since February 1999 for cataract surgery in 350 cases. The different surgical techniques used were manual extracapsular extraction in 52% of cases, phacosection through tunnel incision in 38%, and phacoemulsification in 10%. Our preliminary results show good acceptance of the episcleral anesthesia for both patients and surgeons. Because it is effective and safe, this anaesthtic technique may be an alternative to classic anesthetic techniques in all cases where topical anesthesia is not indicated.
