Abstract
A surgical handpiece having at least two lumens mounted to a body. One lumen is used for aspiration, the second lumen is used to inject heated surgical fluid for liquefying a cataractous lens. A portion of the second lumen is surrounded by an insulated heating element that heats the surgical fluid as it passes through the second lumen. The handpiece may also contain a device for delivering the surgical fluid through the second lumen in metered pulses of a defined volume.
