Abstract
A flexible tip I/A tip assembly includes an elongated sleeve for protecting an eye capsule wound through which the sleeve is inserted and for containing irrigation fluid. The sleeve includes a lumen therethrough and a nipple for removably coupling the elongated sleeve to a handle by elastomeric contact therewith. A retractor with a worm is disposed within the sleeve for transferring aspiration in any angle of the eye capsule. The sleeve and the retractor are held in operational relationship with the handpiece by a nipple which, due to its transparency, enables visual adjustment, alignment, installation and confirmation of the operative relationship therebetween.
