1. A device for cutting a lens within a capsular bag of an eye, comprising:

  • an elongate member comprising at least one lumen and a distal portion;

    a cutting element capable of being configured into a first, retracted configuration with at least a portion of said cutting element being positioned within the at least one lumen, wherein the first, retracted configuration of the cutting element and the distal portion of the elongate member are both sized for insertion into an anterior chamber of the eye through an incision and into the capsular bag,wherein said cutting element comprises a first leg and a second leg, and further wherein, after insertion of the cutting element into the capsular bag, at least one of the first and second legs of the cutting element is configured to move relative to a distal end of the elongate member to expand the cutting element from the first, retracted configuration toward a second, expanded configuration having an open area, wherein a first portion of the open area is distal of the distal end of the elongate member and a second portion of the open area is proximal of the distal end of the elongate member;

    wherein the second, expanded configuration of the cutting element is sized and shaped to permit advancement of the cutting element between the capsular bag and an anterior surface of the lens and further advancement of the cutting element between the capsular bag and a posterior surface of the lens to capture a first portion of the lens within the open area; and

    an actuator operatively coupled to the cutting element, for tensioning the cutting element to reduce the size of the open area and cut the lens.
