The Jensen-Thomas Irrigating-Aspirating (I/A) Cannula, an ophthalmic tool with a 23-gauge size, is intended for effective cortical cleanup in cataract surgery. It has a straight shaft with 0.3mm side ports positioned next to each other, enabling irrigation and aspiration to occur at the same time. The cannula, which measures 32mm in length (excluding the hub), comes with a Luer-lock adapter and 10 inches of tubing.
