The invention is directed to an injector device for introducing an intraocular lens into an eye. The injector device defines a longitudinal axis and includes an injector tip having a through guide channel for the intraocular lens. The channel has a rear inlet and a front outlet. A cassette accommodates the intraocular lens therein and two closure tips are configured for closing the cassette. The closure tips extend in the direction of the longitudinal axis axially farther rearwardly than the rear inlet. A method for prefolding the intraocular lens in the cassette is also disclosed.
