1. A method for performing an ophthalmic procedure comprising:

  • applying a compressive force to an actuation structure of a handle wherein the handle has a handle distal end and a handle proximal end;

    compressing and extending the actuation structure wherein the actuation structure comprises a plurality of actuation arms and wherein each actuation arm of the plurality of actuation arms has at least one inverted actuation joint and wherein each actuation arm of the plurality of actuation arms has at least one extension mechanism;

    extending each actuation arm of the plurality of actuation arms;

    transferring the compressive force to a distal end of an actuation platform of the handle wherein the actuation platform is at least partially disposed in the actuation structure;

    fixing a portion of a wire in a position relative to the actuation platform by an actuation mechanism wherein the wire has a wire distal end and a wire proximal end;

    actuating the actuation platform towards the handle proximal end and away from the handle distal end;

    retracting the actuation platform relative to a handle base of the handle;

    retracting the actuation platform relative to a single housing tube wherein the housing tube has a housing tube distal end and a housing tube proximal end and wherein the housing tube is fixed to a housing tube platform of the handle;

    applying a force to a portion of the housing tube;

    compressing the portion of the housing tube;

    curving the housing tube;

    curving an optic fiber wherein the optic fiber has an optic fiber distal end and an optic fiber proximal end; and

    energizing a laser.
