1. An apparatus for use with a motion source that generates reciprocating linear motion, the apparatus comprising:
a first cutting ring comprising a sharp cutting edge shaped and sized to engage an anterior lens capsule of the eye;
a second cutting ring;
a longitudinal-motion member coupled to the cutting ring, and that is configured to be coupled to the motion source, such that the motion source imparts reciprocating linear motion to the longitudinal motion member; and
a motion-conversion mechanism coupled to the longitudinal-motion member and to the first and second cutting rings and configured to convert the reciprocating linear motion of the longitudinal-motion member into back-and-forth rotational motion of the first and second cutting rings, the back-and-forth rotational motion of the first cutting ring being in an opposite direction of the back-and-forth rotational motion of the second cutting ring, to create a circular aperture in the anterior capsule of the eye by the cutting ring.
