The present disclosure is directed to devices, systems, and methods directed to mounting a plunger tip to a plunger of an IOL injection device. A plunger tip wrench that is operable to releasably retain a plunger tip may be coupled to a holder extending from an end of the IOL injection device to align the plunger tip with the plunger of the IOL injection device. In some instances, the IOL injection device may include a motor and use a back electromotive force (EMF) of the motor to detect a position of the plunger as it is extended to engage the plunger tip. The plunger tip may be positioned relative to the plunger such that the plunger will engage the plunger tip within the entire range of a negative error position and a positive error position.
