    摘要： 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.

    摘要： Various embodiments of a capsularhexis device include a resistive-heating element comprising an electrically resistive, superelastic wire forming a loop between first and second ends of the superelastic wire. The loop may be retracted into a collapsed, retracted position or ejected into an expanded position. The first and second ends of the loop may at least partially extend at an angle from a planar face defined by the loop, to the insulating portion, to form a transitional neck between the loop and the insulating portion. The transitional neck may have a gap between the first and second ends at the insulating portion that is wider than a gap between the first and second ends on the opposing side of the transitional neck. The gap in the loop of superelastic wire may be sufficiently small to allow the loop to form a continuous cut in a capsule of an eye.

    摘要： A capsulorhexis apparatus includes a capsulorhexis probe configured for insertion into an eye through an incision and a pulse generator configured to deliver at least one radio-frequency (RF) pulse to the capsulorhexis probe. The delivered RF pulse has a pre-determined attenuation profile such that the power level of the delivered RF pulse is substantially attenuated over the RF pulse's duration. In some embodiments, the pulse generator is configured to deliver a series of two or more RF pulses to the eye, such that the energy of each of the second and subsequent pulses of the series is substantially attenuated relative to the energy of the immediately preceding pulse.

    摘要： A capsularhexis electrode device and corresponding insertion tool are disclosed. A flexible capsulorhexis electrode device comprises an elastomeric ring, first and second electrically conductive traces disposed at a first face of the elastomeric ring and extending concentrically around the elastomeric ring, and first and second electrically conductive connectors. The first and second electrically conductive connectors are electrically connected to the first and second traces, respectively, and are disposed at opposing points across the elastomeric ring from one another. An insertion tool includes first and second stretcher bars with connectors for mating to the electrode device. One of the stretcher bars translates relative to the other to elongate the flexible electrode device for insertion into the anterior chamber of the eye through a small incision.

    摘要： Various embodiments of a capsulotomy repair device include a resistive-heating element comprising an electrically resistive, superelastic wire forming a loop between first and second ends of the superelastic wire. The first and second ends of the loop may at least partially extend at an angle from a planar face defined by the loop, to an insulating portion, to form a transitional neck between the loop and the insulating portion. The capsulotomy repair device may be positioned in the eye relative to a capsularhexis perimeter to overlap tears in the capsularhexis periemeter to remove the tears by forming an adjusted capsularhexis perimeter by burning around the tear.
