A surgical instrument for both chopping and splitting the nucleus of an eye has a handle housing a shaft mounted within a guide tube which slides into and out of the instrument to bring first and second jaws into and out of contact with one another. The jaws are planar and positioned approximately perpendicular with the axis of the handle. The bottom edges of the jaws are brought into alignment to form a cutting edge when the jaws are forced together, and separate to perform a splitting action within a cut when the jaws are moved apart.

Nucleus chopper and splitter

A surgical instrument which both incises and splits the nucleus of a lens has a pair of 5 spring steel segments slidably received in a metallic tube. Each segment terminates in a tip. As the spring steel segments are drawn into the tube the tips come together to form a cutting edge useful for incising the lens. When the segments are extended from the tube the tips separate, forcing the incision open until the lens is split.
