Abstract
The present invention relates to a cartridge for an injector system, including a folding body for implanting an intraocular lens into an eye. The cartridge comprises a receiving region for at least one lens and at least one movable haptic slider for sliding a lens haptic onto or to an optical portion of the lens. The haptics can thus be brought into a defined position such that, when folding and ejecting the lens from the injector, they can be rolled in a defined manner into the optical portion of the lens so as to guarantee insertion and unfolding of the lens in the eye in the most reproducible manner possible.
Claims21
An injector system for implanting a lens into an eye, comprising:
- an injector body having a front end and a rear end;
- a cannula arranged at the front end of the injector body, which provides a transport channel for the lens to be implanted;
- a cartridge comprising a receiving region for the lens and at least one movable haptic slider for displacing a lens haptic within the cartridge, wherein the cartridge is arranged such that the lens can be fed into the transport channel;
- a folding body insertable into the cartridge and receiving region of the lens, for pushing the lens into the transport channel in such a manner that the lens is foldable around the folding body;
- and
- a slider arranged within the injector body so as to be displaceable, and which can be pushed through the front end of the injector body and into the transport channel in such a way that the lens can be ejected from the transport channel,
- wherein the haptic slider is mounted to the cartridge so as to be movable.
