ABSTRACT:
An irrigation and aspiration handpiece tip for enabling safe vacuuming and polishing of a capsule generally includes an aspiration tube for removal of tissue from an eye which in vacuum communication with a first vacuum port applies vacuum within an eye in order to remove tissue therefrom. The aspiration tube also includes a second vacuum port for controlling vacuum pressure within the vacuum tube, with the first vacuum port and the second vacuum port being disposed in the aspiration tube in a spaced-apart angular relationship with one another. In addition, an irrigation tube is provided for introducing irrigation fluid in order to flush tissue towards the first vacuum port.
