Abstract
A cannula for an eye-surgery instrument, employed to shatter the lens of the eye by high-frequency oscillation and to suction out the fragments. It accommodates a suction channel with a section that is wider toward the tip of the cannula. The wider section (20) comprises at least two straight bores (8, 9, & 10), one wider than another, extending coaxial with the suction channel (7) into the cannula (1) from its tip (5). Fragments of the shattered lens accumulate in the bores in accordance with size, where they can be further fragmented by ultrasound.
