The invention relates to a device that permits an intra-ocular lens, which has been elastically deformed, to be injected through a cannula (5) into an eye by means of a ram (6) with a translatory displacement action. 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.

L'invention concerne un dispositif permettant d'injecter une lentille intraoculaire déformée de manière élastique, dans un oeil, par l'intermédiaire d'une canule (5), au moyen d'un coulisseau (6) pouvant décrire un mouvement de translation dans le dispositif. Le dispositif selon l'invention comprend un logement de lentille (1) qui peut être inséré dans ledit dispositif. Ce logement de lentille comporte une base élastique (8) qui peut être déformée, par flexion, pour passer d'une position ouverte de relâchement à une position fermée sous tension. Lors de la déformation, la lentille intraoculaire qui est en contact avec le logement de lentille (1) est courbée progressivement, ce qui permet de déformer la lentille intraoculaire avec précaution et de l'injecter avec précision et fiabilité.
