摘要：
I describe a new cannula for delivery of sub-Tenon's local anesthetic solution. The cannula has a rigid structure, a 19-gauge diameter, and a shaft with a gentle curve, specifically designed to follow the contour of the globe. Anteroposterior flattening of the tip facilitates advancement of the cannula within the potential Tenon's-space tissue plane. Without the acute angulation of the shaft of the Bishop-Harmon-style cannula, it is easier to follow the globe contour and create less tenting-up of conjunctiva.
