SubTenon Cannula
Sub Tenon cannulas are specialized ophthalmic instruments designed for the safe and controlled administration of local anesthesia into the sub-Tenon’s space during ocular surgeries. Commonly used in procedures such as cataract extraction, glaucoma surgery, and vitrectomy, these flexible cannulas allow for effective regional anesthesia with minimal patient discomfort and reduced risk of complications compared to traditional needle-based techniques. Made from medical-grade stainless steel or soft, flexible polymer materials, Sub-Tenon cannulas are available in various lengths and gauges—typically with blunt, rounded tips to ensure atraumatic insertion and precise delivery. Compatible with luer lock syringes, they provide a secure, leak-free connection during anesthetic administration. Ideal for ophthalmologists and anesthesiologists, Sub-Tenon cannulas enhance patient safety, reduce globe perforation risk, and improve surgical outcomes by offering a reliable alternative to retrobulbar or peribulbar blocks.
