ABSTRACT:
An injector head forming a hollow cone of spreadable leaves is partially inserted into a minimum size eye incision to inject a temporarily folded intraocular lens into the eye without stressing the incision. An injector device having a holder with a bore holding the lens in folded state is connected to the cone, and a plunger of the device inserted in the bore pushes the lens into and through the cone for controlled gradual injection into the eye and simultaneous controlled gradual unfolding therein.
