INJECTOR FOR INTRAOCULAR LENSES

An intraocular lens implantation injector has a base body and an elongated actuation element projecting into a base body rear section and movably guided along an actuation axis. Actuation element movement is generated selectively by axial push actuation or by a screw actuation about the axis. The actuation element features an external thread at least on one section. At least one spring arm arranged at the base body has an inner surface thread engagement structure facing the external thread. A switch element, interacting with the spring arm, is rotatably or displaceably arranged on the base body. The switch element interacts with the spring arm via an operative contact. At least one switch element inner surface and/or spring arm outer surface involved in the operative contact is angularly inclined to the axis. Switch element rotation/displacement generates spring arm elastic deformation towards/away from the axis, thereby engaging/disengaging the thread engagement structure.
