ABSTRACT:
A hand-operated injector for inserting a lens into an eye has a grip body (1) with a lens holder (13) for holding a lens, and a plunger (2) arranged displaceably in the grip body (1) for guided insertion of the lens into the eye. An actuating means (5, 6) for displacing the plunger (2) relative to the grip body (1) is arranged on the plunger (2), which actuating means (5, 6) is rotatable relative to the plunger (2). The injector can thus be rotated through any desired angle, without having to substantially change the position of the hand pressing on the plunger (2), in particular the position of the thumb.
