Beschreibung
Zusammenfassung:	Apparatus (100) for use with a motion source that generates reciprocating linear motion. The apparatus includes a cutting ring (120) comprising a sharp cutting edge shaped and sized to engage an anterior lens capsule of the eye (20) and a longitudinal-motion member (150) 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. The apparatus additionally includes a motion-conversion mechanism coupled to the longitudinal-motion member and to the cutting ring and configured to convert the reciprocating linear motion of the longitudinal-motion member into back-and-forth rotational motion of the cutting ring to create a circular aperture in the anterior capsule of the eye by the cutting ring. Other applications are also described.
