Abstract
Described is a phacoemulsification device for eye surgery that generally comprises an ultrasonically vibrating aspiration needle that withdraws ocular material from inside of the eye. The ocular material withdrawn from the eye is equally replaced with irrigation fluid provided through irrigation ports in an irrigation sleeve surrounding the aspiration needle. In the event the aspiration needle stops withdrawing ocular material, such as if it becomes occluded with a chunk of ocular material, irrigation fluid is directed to the outside of the eye via at least one irrigation aperture to keep the eye cool where the needle is ultrasonically vibrating.
