Abstract
Disposable irrigation and aspiration apparatus is disclosed for use during extracapsular extraction of a cataract from a person's eye. A separate handpiece is provided to allow the surgeon to apply only irrigation flow to the eye during the operation. The irrigation-aspiration and irrigation handpieces are connected by a valve to give the operating surgeon his choice of instruments without changing the rate of irrigation flow. The outer surfaces of both handpieces are obstruction free to give the surgeon a high degree of preciseness and maneuverability.
