ABSTRACT OF THE DISCLOSURE An intraocular surgical instrument includes an elon- gated inner tube that is axially movably connected at a first end to a handpiece, and comprises a cutting edge at a distal end. An elongated outer tube is disposed coaxially with the inner tube, is connected at a first end to the handpiece, and includes a cutting edge at a distal end. A first clearance is provided between the inner tube and the outer tube at a first rearward region and a second region adjacent to the cutting edges, such that the cutting edges are maintained in a cutting relationship. A second clearance, larger than the first clearance, is provided at a third region disposed between the first and second regions.
