A cartridge (120 220) for storing and implanting an intraocular lens (IOL) (50) comprises a first part (122) and a second part (124) that are movable relative to one another from a storage configuration, in which interior surfaces of the first and second portions define a storage chamber (140) for storing the IOL in an unfolded state, to an implanting configuration, in which the interior surfaces of the first and second portions together define a smooth-bored implanting chamber (140 ) for retaining the IOL in a folded state. According to a first aspect, the first and second portions (122, 124) are hinged together, whereas according to a second aspect, the first and second portions (222, 224) are slidably interconnected.
