The device contains a lens holder (1), which can be inserted into said device. The lens holder contains an elastic base (8), which is deformable in such a way that it can be converted from a relaxed, open position into a tensioned, closed position by bending. During said deformation, the intra-ocular lens that is in contact with the lens holder (1) is subjected to an increased curvature. This permits the careful deformation of the intra-ocular lens and a precise, reliable injection of the latter.
