ABSTRACT:
An irrigating sleeve for use in combination with the cutting tip of a phacoemulsification handpiece containing a base having a nose and a hollow interior; a tube connected to the base at the nose having an interior surface, an open end opposite the nose and a longitudinal bore to receive the cutting tip in communication with the hollow interior of the base; and a rough texture comprised of random bumps and pits on the interior surface of the tube for reducing the amount of surface contact between the cutting tip and the interior surface of the tube during tube compression and for bathing the cutting tip continuously in a lubricant.
