Abstract
An adapter for a surgical hand piece having a single lumen work tip with an open end and a small lateral hole is designed to convert the work tip to infusion/aspiration (I/A) cleanup of lens epithelial cells after phacoemulsification. The adapter is in the form of a sleeve adapted to be slid over the distal end of the work tip. The sleeve includes at least one aspiration hole located toward the distal end of the sleeve. When the distal end of the sleeve is at a first distance Lfrom the distal end of the work tip, aspiration occurs through the aspiration hole of the sleeve and the open end of the work tip. When the distal end of the sleeve is at a second and smaller distance Lfrom the open end of the work tip, aspiration through the open end of the work tip is blocked by the sleeve and aspiration occurs through the aspiration hole of the sleeve and the lateral hole in the work tip.
