1. A method, comprising the steps of:
pushing an intraocular lens with a plunger along a lens travelling axis within an intraocular lens insertion apparatus, the plunger including
a rod having a proximal portion and a distal axial portion with a lower protrusion defining a distal end and a width in a third direction,
an upper protrusion, defining a width in the third direction and a distal end, that extends distally beyond the lower protrusion in a first direction defined by the lens travelling axis, that is perpendicular to the third direction and that is spaced from the lower protrusion in a second direction that is perpendicular to the lens travelling axis and to the third direction, wherein the distal end of the upper protrusion defines a distal-most end of the plunger, and
an indentation defining a slot that has at least a portion thereof located between the upper and lower protrusions and that defines a width, with a midpoint, in the third direction that is at least equal to the width of the lower protrusion and that is greater than the width of the upper protrusion,
wherein the upper protrusion is offset from the slot midpoint in the third direction; and
applying a force to the upper protrusion in a direction orthogonal to the lens travelling axis.
