1. An intraocular lens insertion apparatus, comprising:

  • an outer body that defines a lens movement direction, that includes a nozzle and a lens placement section with lens supporting surfaces having portions that are spaced from one another in a spacing direction that is perpendicular to the lens movement direction, and that is configured to store an intraocular lens, having an optic with a diameter and haptics with respective free ends, in such a manner that diametrically opposed portions of the optic are on the lens supporting surface portions that are spaced in the spacing direction that is perpendicular to the lens movement direction, one of the haptics is a proximal haptic, and one of the haptics is a distal haptic; and

    a plunger, at least a portion of which is carried within the outer body, that is movable relative to the outer body and which has a distal region that defines a longitudinal axis, the distal region includinga bottom wall having an upper surface and defining a width in a direction transverse to the longitudinal axis of the distal region,a lens contact surface extending downwardly from the bottom wall upper surface,a top wall defining a width in a direction transverse to the longitudinal axis of the distal region that is less than the width of the bottom wall, anda lateral wall that extends from the bottom wall to the top wall in a direction perpendicular to the spacing direction that is perpendicular to the lens movement direction,the top wall, bottom wall and lateral wall together defining a recess that is located above the bottom wall, that extends proximally from the lens contact surface, that has a first lateral side that is open, a second lateral side that is closed by the lateral wall, and an open distal end, and that is configured to hold a portion of the proximal haptic when the proximal haptic is bent such that the free end is positioned over the optic.
