An injector for implanting a folded intraocular lens is described, with which a folded lens can be inserted into the capsula of the lens of the eye through an opening incision of approx. 3 mm in the eye. Essentially, the new injector only consists of three parts, namely a one-piece body (2), a pivoting flap (3) which is provided with a folding rib (11) and by means of which the lens (20) is held in an unfolded state in a first position above the transporting channel and is slid folded into the transporting channel by radial pressure, and a third component, the slider (4) through which the folded lens (20) can be slid forwards in the longitudinal direction and out of the injector into the eye.

L'invention concerne un injecteur pour implanter un cristallin artificiel plié, permettant d'introduire un cristallin plié, à travers une ouverture d'environ 3 mm découpée dans l'oeil, dans la capsule du cristallin. Ce nouvel injecteur est caractérisé en ce qu'il ne présente que trois parties, à savoir un corps d'une seule pièce (2), un volet basculant (3) pourvu d'une nervure de pliage (11) et permettant de maintenir le cristallin à l'état non plié dans une première position se trouvant au-dessus du canal de transport et de le faire coulisser dans le canal de transport, à l'état plié, par une pression dans le sens radial, ainsi qu'un troisième élément constitutif, le coulisseau (4), qui permet de faire avancer le cristallin plié (20) dans le sens longitudinal, puis de le faire sortir de l'injecteur pour l'introduire dans l'oeil.
