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

  • introducing a cutting element into an anterior chamber of the eye, wherein at least a portion of said cutting element is positioned in a first, retracted configuration within a lumen, and wherein said cutting element is movable from the first configuration toward a second, expanded configuration comprising a preset, unbiased shape as the portion of the cutting element is extended from the lumen, at least part of the cutting element forming a loop with an open area as the cutting element is moved toward the second configuration;

    positioning the cutting element in the first configuration, through an opening in the capsular bag, over an anterior surface of the lens with the lens being whole and inside the capsular bag;

    extending the portion of the cutting element from the lumen to move the cutting element from the first configuration toward the second configuration, the open area increasing in size as the portion of the cutting element is extended further from the lumen, wherein the cutting element advances between the capsular bag and the anterior surface of the lens as the cutting element moves toward the second configuration;

    positioning the cutting element in the second configuration around a portion of the lens between a posterior portion of the capsular bag and the lens; and
