Abstract: An intraocular lens (IOL) injectors and associated methods are described. The IOL injectors may include a collapsible portion configured to reduce the length of the IOL injector when the collapsible portion is altered from an uncollapsed configuration to a collapsed configuration. In some instances, an IOL may be advanced from a storage location to a dwell location when the collapsible portion is altered from the uncollapsed configuration to the collapsed configuration. The IOL injectors may also include a combination push and screw drive.
