    Abstract: A surgical sleeve lens removal by laser or ultrasonic surgical instruments, also used on the forefront of an ophthalmic irrigation/aspiration surgical instrument. The surgical sleeve consists of a hollow sleeve body (20) with its proximal end (22) adapted to fit the surgical instrument and its distal end (24) having a tubular shank (30). The shank has a truncated cone contour (32) on its extremity and at least one annular protuberant appendage (34) integrally formed with the shank (30) and extending from an outside surface of the distal end, for manipulation of intraocular tissue. The appendage (34) has a sloped surface (36) and extends either partially or completely around the periphery of the sleeve body (20). The appendage (34) may consist of single or multiple elements but in any case the appendage has a larger outside diameter than the shank.
