ABSTRACT:
A phaco-emulsification needle is provided for use with a plastic or elastomeric sleeve, the needle having a mid-region portion defining a plurality of outwardly extending projections forming longitudinally-oriented grooves that provide adequate irrigant flow rates to the anterior chamber of the eye, even when the entry wound compresses the sleeve against the outer surface of the needle, thereby reducing the risk of collapse of the anterior chamber due to inadequate irrigant flow and reducing the risk of excessive heat transmission to the entry wound.
