Description
TECHNICAL FIELD The present invention relates to a container system for storing an intraocular lens to be implanted. BACKGROUND Intraocular lenses are lens implants or artificial lenses to replace the natural lens of a human eye. They are in particular used to replace the lenses of an eye affected by cloudiness (cataract) of the lens. By surgery, the affected lenses are removed and the intraocular lenses are inserted. Insertion into the eye is accomplished by means of a so-called injector, for example. It is important in this context that the surgical incision through which an intraocular lens is implanted is as small as possible (e.g. about 2.5 mm). This can provide for a fastest possible healing process without complication and possibly also avoids the need for suture. To be able to implant intraocular lenses which generally have a diameter of about 5 to 7 mm, the lenses must be foldable so as to fit through the small incision of about 2.5 mm. An injector for folding and inserting a folded lens into the human eye is, for example, described in international patent application WO 2011/155887 A1. The content of this patent application, in particular with respect to the magazine described therein is fully incorporated into the present patent application by reference. What is described therein is an injector for implanting or inserting a temporarily folded intraocular lens, which injector can be used to insert the folded lens into the lens capsula of the eye through an incision of the required size of about 2.5 mm in the eye. In one embodiment, the magazine with a lens loaded therein is connected to the injector only shortly before the operation, for loading the injector system. Thus, the lens can be loaded into the magazine in advance, under controlled conditions, for example by a manufacturer of lenses. The loaded magazine may then be stored under sterile conditions in a storage container, for example in a blister package which is preferably filled with a sterile liquid. SUMMARY Against this background described above, the present invention is based on the object to even further improve the introduction of the lens into the eye. In particular it should be possible to roll up a lens to be implanted even smaller. These objects are achieved by the container system according to the independent claim. Advantageous embodiments are specified by the subject matter of the dependent claims, the description and/or the drawings. It has been found that the temperature of the lens plays an important role for the folding of the lens, the insertion of the lens into the eye, and/or for the deployment (unfolding) of the lens. A heated lens is much more supple and flexible and can be rolled up smaller, so that a cut opening (incision) in the eye can be further reduced. Moreover, a warm lens will deploy faster after having been inserted into the eye. Generally, the invention therefore contemplates to enhance the storage container described in the prior art and briefly referred to as container below, so that it is provided with a heating device. In detail, the invention provides a container system for heating and/or storing a lens, which comprises the following components: a container for storing at least one lens pre-loaded in a magazine, and a heating device integrated in the container, and/or a connection device for a heating device, for heating the lens pre-loaded in the magazine within the container. Preferably, the lens is an intraocular lens intended to be implanted into the eye. In contrast to the prior art, the magazine is not placed in a heating bath. Rather, according to a first variant of the invention the container is equipped or produced with the heating device. The heating device is integrated with the container. Heating device and container form a functional unit. According to a second variant of the invention, the container is not directly equipped with the heating device. The container is provided with the connection device for the heating device. The connection device is integrated with the container. Connection device and container constitute or form a functional unit. The heating device is provided separately in this case. It may for instance be designed as a kind of charging station to which the container can be connected via its connection device. According to the invention, the lens as such is not stored or storable in the container but rather is pre-loaded in a magazine and/or on the injector. The magazine is or can be placed in the container together with the lens stored in the magazine, optionally together with the injector. In particular, in the first embodiment it is possible in this way to directly connect the magazine to an injector after opening of the container. In the second embodiment it is possible to stably position the pre-loaded injector in the container to be able to heat the magazine and the lens. In a first embodiment, a magazine including a lens is already disposed in the container in t
