The object of providing a device for reversibly attaching an implant to an eye, with which the implant can be attached in a simple way to the eye and can if necessary be detached or removed from the eye, is achieved according to the present invention by means of a device for attaching an implant by means of a pin that comprises a substantially elongated shaft, wherein the implant includes an implant film for contacting living tissue or nerves in the visual system of the eye and the implant film has an opening through which the shaft of the pin can be at least partially inserted, characterised in that the device includes a holding element that can be arranged on the shaft of the pin so that the holding element engages on the shaft of the pin and is fixed in an attachment position to the pin. By means of the device according to the invention the implant is on the one hand reliably attached, but can if necessary be detached from the retina by removing the holding element or retainer, wherein the pin anchored in the eye does not have to be removed at the same time, but can be re-used. Damage or injury to the tissue of the eye that would otherwise be associated with the removal of the pin can thereby also be avoided.
