An ophthalmic working-channel cannula is a reusable surgical tool used to create a controlled passage through the eye’s outer layer (sclera) during complex posterior segment procedures. It allows precise insertion of instruments and fluid irrigation to stabilize intraocular pressure, reducing risks like retinal detachment or bleeding during surgery.
These devices are typically regulated as surgical instruments, often requiring sterilization between uses. They may be classified differently depending on jurisdiction, and supply chains often involve medical device distributors or surgical supply companies specializing in ophthalmic tools.
