A device for inserting an intraocular lens (IOL) into an eye includes a tubular body member with an inner surface and a plunger with an gripping device that is receivable within the body member. The gripping device includes a locking member and is configured such that when urged longitudinally in a distal direction, the gripping device is movable in the distal direction within the body member. However, when urged longitudinally in a proximal direction, the gripping device is prevented from moving in the proximal direction by the locking member engaging with the inner surface of the body member. As such, inadvertent movement of the plunger in the proximal direction caused by pulling back on the plunger is substantially prevented. If proximal movement of the plunger is desired, then the plunger may include handle that is operatively coupled to the gripping device such rotation of the handle causes the handle to move longitudinally in the body member. Accordingly, the plunger may be advanced or moved distally by longitudinally pushing the handle and / or by rotating the handle.
