A tip (10,110) for a surgical handpiece is provided with two coaxial tubes or channels mounted within a body or cap (12,112), an outer tube defining a centerline (11,111); the tip cap sealing the distal ends of the inner tube (22,122) and the outer tube (20,120), the tip cap having an aspiration port (14,114) in fluid communication with the inner tube, and an irrigation port (16,116) in fluid communication with the annular gap, the aspiration port and the irrigation port being offset relative to the centerline. The tip has one or more features that shape the fluid discharge so as to optimize the performance of the handpiece for varying parts of the surgical procedure. <IMAGE>
