Sub Tenon Cannula, Curved, Tri-Port, 21ga, 22mm (7/8")

A curved 21ga sub‑Tenon cannula with a tri‑port distal tip, this 22mm (7/8 inch) instrument spreads anesthetic evenly within the posterior sub‑Tenon space rather than jetting from a single aperture. The curve follows the scleral contour for smooth advancement to the equator. The 21ga lumen balances delivery rate with controlled placement.

Features & Benefits
