PROBLEM TO BE SOLVED: To provide an insertion device for surgical implantation of an intraocular lens in an eye. SOLUTION: The device comprises a plunger 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 212 of the plunger. The spring 250 is elastically compressed when the plunger is advanced in a distal direction, thus creating a forward biasing force for improved control of the insertion process. In an advantageous embodiment, the spring 250 may be pre-biased, and the spring force acts only in a final phase of advancing the plunger. COPYRIGHT: (C)2007,JPO&INPIT
