Corneal aspiration cannula and method of using

摘要

An aspiration cannula is used in tectonic lamellar keratoplasty. The cannula is hand manipulatable and aspirates irrigation fluid and repositions a corneal cap or flap during corneal surgery. The cannula comprises a hand manipulatable elongated tube having an inlet end with a plurality of ports spaced apart along the length of the tube for aspirating irrigation fluid around a corneal incision interface and an outlet end for disposing the fluid.
