Eye surgery cannulas are fine tubes designed to deliver or remove fluids or medications during an operation. An ophthalmic cannula is crafted for smooth, atraumatic insertion into the anterior or posterior segment to perform irrigation, aspiration, and tissue manipulation. They are used with a bulb irrigator and come in many configurations, including lacrimal, anterior chamber, LASIK irrigation, and hydrodissector designs, allowing surgeons to select the ideal tip shape and gauge for each procedure.
