A capsularhexis device (10) comprises a resistive-heating element (12) formed from an electrically resistive, superelastic wire (14) formed into a loop. A bare surface of this loop is applied to the anterior capsule and electrically heated to define a rhexis boundary, such that a smooth circular or oval capsule portion may be removed. In some embodiments, the superelastic wire is formed to include a loop, so that first and second ends of the wire are adjacent to one another and extend away from the loop to form a lead section. An electrically insulating material (17) may completely or partly surround the first and second ends of the wire so that the first and second ends of the superelastic wire are electrically separated. A handle (19) engages at least a portion of the lead section so that the loop-shaped heating element may be moved in and out of the anterior chamber.
