An irrigation and aspiration tubing system for use with surgical handpieces and irrigation fluid supplies has a flexible tube with first and second lumens formed integrally along its length, with a first lumen used for transporting irrigation fluid to the handpiece and a second lumen used for aspiration of fluid and emulsified particles from a surgical site. The cross-sectional area of the first lumen is selected to provide a cross-sectional area available for fluid flow in excess of the cross-sectional area of a standard surgical irrigation tubes. The system also includes at least one adaptor to allow the tubing to be attached to known surgical handpieces. Preferably, a second adaptor is also provided allowing attachment to sources of irrigating fluid and aspiration vacuum. One said lumen is formed integral with either the interior or exterior surface of the flexible tube.
