<p>An insertion device for surgical implantation of an intraocular lens in the eye is disclosed. The device comprises a plunger (200) which is displaceable within a sleeve (110) for guided insertion of the lens. The plunger has a hollow portion (212), and a spring (250) is disposed within the hollow portion of the plunger. The spring is elastically compressed when the plunger is advanced in a distal direction, thus creating a rearward biasing force for improved control of the insertion process. In an advantageous embodiment, the spring may be pre-biased, and the spring force acts only in a final phase of advancing the plunger.
