Abstract
A phacoemulsification tip, including an aspiration tube presenting a cutting tip at a distal end. The aspiration tube has a tube wall presenting an internal face and an external face. The internal face supports at least one internally extending internal ridge. The at least one internal ridge presents an internal distal face, an internal proximal face and an internal apex. The internal distal face meets the internal face at an acute angle measured internally. The at least one internal ridge is structured to engage lens fragments separated from a crystalline lens to enhance proximal movement of the lens fragments and to inhibit distal movement of the lens fragments through the aspiration tube.
