1. A projector device for projecting a light beam onto a retinal area of a human eye, comprising
a projector for projecting a light beam from the exterior of a human eye through a pupil and onto a modified retinal area of the eye, the light beam being a single light beam;
wherein the projector comprises a sensor unit that monitors an eye pupil diameter of the eye onto which the light beam is projected and comprises an adjustment unit that adjusts an exit pupil diameter of the light beam such that the exit pupil diameter of the light beam is set smaller than the eye pupil diameter of the eye; and
wherein the projector comprises an alignment device that aligns a central axis of the light beam with a viewing axis defined by an axis passing through a center of the eye pupil and a center of a retinal implant of the eye.
