Injector for intraocular lenses

An injector for implantation of an intraocular lens, comprising:

• a base body;
• an elongated actuation element which projects at least partly into a rear section of the base body and which is movably guided along an actuation axis, wherein a movement of the actuation element into the base body is generated selectively by a push actuation along the actuation axis or by a screw actuation about the actuation axis, and wherein the actuation element features an external thread at least on one section;
• and
• a switch element, which can be rotated about the actuation axis, arranged on the base body and having a passage, the actuation element extending through the passage;
• wherein;
• at least one spring arm is arranged at the base body, the spring arm having a thread engagement structure on an inner surface facing the external thread;
• the passage of the switch element features at least one inner surface having an inner radius varying at least in sections in a circumferential direction;
• and
• an outer surface of the spring arm is in contact with the inner surface of the switch element, so that upon a rotation of the switch element about the actuation axis, due to the varying inner radius at the circumferential position of the spring arm, an elastic deformation of the spring arm towards the actuation axis and away from the actuation axis is generated, whereby the thread engagement structure is selectively engaged or disengaged with the external thread.
