Abstract
An injector for inserting an intraocular lens into an eye, comprising a main body () and a plunger (). A guide element () is connected to the distal end of the plunger to laterally guide the plunger during movement along a longitudinal axis (L). The distal end of the guide element has a structure for fastening a plunger needle to the guide element. A radial guide pin () is in aligned radial bores of the guide element and plunger and extends into a longitudinal slot () of the main body to prevent twisting and to secure the guide element to the plunger. A retaining element () interacts with a running surface on the perimeter of the plunger, the running surface having a variable radial distance from the longitudinal axis so as to cause an axial resistance force which depends on the axial position of the plunger.
