1. A membrane delamination device for delaminating a membrane from a retina of an eye, comprising:
a blade;
a first lever coupled to the blade; and
a second lever coupled to the blade, wherein:
the first lever and the second lever are at least partially housed by a first shaft of a hand-piece;
the first lever is fixedly coupled to the first shaft;
the second lever is fixedly coupled to the hand-piece;
the blade at least partially extends beyond a distal end of the first shaft;
the membrane delamination device is configured to be actuated as a result of longitudinal movement of the second lever within and in relation to the first shaft; and
the second lever moves longitudinally within and in relation to the first shaft due to an application of force to the second lever through the hand-piece.
