Apparatuses, systems, and methods for folding an intraocular lens and inserting an intraocular lens into an eye are disclosed herein. In some instances, a system for folding an intraocular lens may include a folding pin, a guide pin rotatable about a longitudinal axis of the folding pin, and a stage laterally moveable relative to the folding pin. An intraocular lens may be secured between the folding pin and the guide pin and be folded onto the folding pin during rotation of the guide pin. A retention member may be used to hold the folded intraocular lens onto the folding pin.
