1. A cartridge, comprising:
a first opening;
a second opening;
a channel, which extends from the first opening to the second opening and which has a taper;
an intraocular lens arranged in the channel between the first opening and the second opening; and
a cartridge plunger arranged in the channel between the intraocular lens and the second opening and set up to first preload the intraocular lens by displacing the cartridge plunger toward the first opening, then to fold the intraocular lens by displacing the intraocular lens in the taper, and then to push the intraocular lens out of the channel via the first opening,
wherein the cartridge is set up to be coupled with a syringe, such that a fluid can be forced into the channel via the second opening with the syringe and the cartridge plunger can thereby be propelled in a direction of insertion toward the first opening,
wherein the cartridge plunger has a first cartridge-plunger longitudinal end, a second cartridge-plunger longitudinal end, and a fluid line, which extends from the first cartridge-plunger longitudinal end to the second cartridge-plunger longitudinal end, and via which the fluid can be forced in from the second cartridge-plunger longitudinal end to the first cartridge-plunger longitudinal end and then to the intraocular lens,
wherein the cartridge plunger seals the channel in an area of the first cartridge-plunger longitudinal end, such that no fluid can pass through the cartridge plunger on its outer circumference, and
wherein the cartridge plunger has a first portion, which has the first cartridge-plunger longitudinal end and which is flexible, a second portion, which has the second cartridge-plunger longitudinal end, and a third portion, which is arranged between the first portion and the second portion and which has a recess, which is set up to receive parts of the first portion when the cartridge plunger enters the taper.
