A capsularhexis device includes a loop-shaped cutting portion formed from flexible, superelastic metal strips separated by an insulating layer, and configured so that the cutting portion may be retracted into a tubular insertion cartridge for insertion into and removal from the eye, and extended from the insertion cartridge for the capsularhexis procedure. In its extended configuration, the cutting portion forms a cutting loop such that a free end of the cutting loop is proximate a connecting end of the cutting loop, with the connecting end joined to a shaft portion. The shaft portion extends into the insertion capsule, and is used to move the cutting portion in and out of the insertion cartridge.
