ABSTRACT:
An irrigation-aspiration device includes an outer cannula and an inner cannula reciprocatable within the outer cannula. Irrigating fluid is flowable between the inner and outer cannula. The inner cannula is bent along the length thereof and springy so as to be biased near an outer end thereof against one side of the outer cannula. A port opens into the inner cannula and is positioned so as to selectively abrade against an operable end of the outer cannula with a biting or cutting action. An inner lumen of the inner cannula is connected to a vacuum or suction source such that during surgery fragments of the eye may be drawn into the port of the inner cannula and cut by abrasion against the end of the outer cannula and thereafter pulled through the inner cannula and away from the eye. This cutting action may be utilized to remove attached fragments of the anterior capsule, pieces of vitreous, nuclear and cortex material, and to biopsy the iris.
