A cartridge includes a first opening, a second opening, a channel, an intraocular lens arranged in the channel, and a cartridge plunger arranged in the channel and configured to firstly preload the intraocular lens by moving the cartridge plunger towards the first opening, then to fold the lens by moving it in the tapered region, and finally to push the lens out of the channel via the first opening. The cartridge is configured to be coupled to a syringe such that a fluid can be injected into the channel, and as a result the cartridge plunger can be propelled in a movement direction towards the first opening. The cartridge plunger includes a first cartridge plunger longitudinal end, a second cartridge plunger longitudinal end, and a fluid line via which the fluid can be injected from the second to the first cartridge plunger longitudinal end and finally to the intraocular lens.

Cartridge and injector with the cartridge

An injector for inserting an intraocular lens into a capsular bag of an eye includes an injector body having an injector tip defining an opening. The injector body has a proximal end facing away from the opening and has a distal end. A first piston is directed toward the opening and is configured to contact and displace the intraocular lens. A second piston is operable from outside of the injector and the first piston and the second piston are each configured to be longitudinally displaceable along the injector axis. A handle is operated from outside of the injector and is configured to be coupled to the first piston so that when the pistons are in the decoupling state, the first piston is displaced toward the opening and relative to the second piston by moving the handle.

Injector having a first piston and a second piston

The invention relates to an injector assembly having: a folding chamber which is designed to receive an intraocular lens which has an optical body and two haptic elements; a holder; a folding wedge which is attached to the holder and is designed to be introduced into the folding chamber via a folding chamber opening, thereby folding the intraocular lens; and a first slider and a second slider which are each designed to push one of the two haptic elements onto the optical body by means of a displacement of the respective slider from a starting position to an end position, the holder being designed to drive the first slider and/or the second slider from the starting position to the end position by means of a movement of the holder towards the folding chamber.

Injector assembly for inserting an intraocular lens and injector

The invention relates to an injector assembly comprising a folding chamber which is designed to receive an intraocular lens having a lens body and two haptics, and comprising a holder, a folding wedge which is attached to the holder and is designed to be introduced into the folding chamber in an insertion direction via a folding chamber opening and to thereby fold the intraocular lens, and two sliders which are each designed to shift one of the two haptics onto the lens body via a shifting of the respective slider out of an initial position and into an end position, wherein at least one of the two sliders has a stop which is designed to abut a component attached to the holder in the initial position of the at least one slider, whereby a movement of the component is blocked and the folding wedge is thereby not permitted to fold the intraocular lens, and said stop is designed to permit the movement of the component in the end position of the at least one slider and the folding wedge is thereby permitted to fold the intraocular lens.

The invention relates to an intraocular lens comprising an optics body and a haptic which has a first component with a latching protrusion and a second component with a latching recess, the latching protrusion and the latching recess being arranged at a distance from one another when the haptic is arranged in a relaxed state and being configured to engage with one another when, proceeding from the relaxed state, the haptic is moved in the direction of the optics body into a completely compressed state of the haptic via a partially compressed state of the haptic, the haptic being formed by a single piece and having a haptic cutout which is delimited by the first component and the second component.
