Abstract
An improved irrigation fluid conduit for use with a coaxial surgical irrigator-aspirator for ophthalmic surgery comprises a hollow body adapted for attachment to the surgical irrigator-aspirator and a thin-walled tubular sleeve extending from the hollow body to surround the aspiration conduit of the instrument. The body and sleeve are homogeneously molded from polypropylene, which permits a rigid thin wall sleeve having a wall thickness not greater than 0.006 inches and which is transparent for increased visibility of the adjacent tissues.
