A system and tool for performing a capsulotomy procedure. The system includes a capsulotomy and movement control unit providing electrical current and movement control, and a capsulotomy tool, and an extendable-retractable burning element coupled to the tool, and a slidable shaping element. A capsulotomy and movement control unit provides electrical current to the burning element and movement control for extending and retracting the burning element. When the burning element is in a flattened, retracted configuration, the tip of the tool can be inserted through a relatively small corneal incision. Then, the burning element is opened to a full circular, extended configuration, by pressing the shaping element against both joints of the bands, allowing a capsulotomy by applying an electrical pulse to the burning element.
