Provided is an intraocular lens insertion device capable of omitting a repeated operation after the intraocular lens is inserted into the eye. The intraocular lens insertion device (1) comprises a lens setting part (11) for mounting an intraocular lens (5) having an optic (6) and one or two or more supporting portions (7a and 7b) disposed at the outer edge of the optic (6), a plunger (4) for pushing out the intraocular lens (5) mounted in the lens setting part (11), and a nozzle (13) for releasing the intraocular lens (5) pushed out by the plunger (4). This plunger (4) includes a lens contact portion (32) for abutting against the outer edge of the optic (6), and a pushing portion (33) for pushing out the supporting portion (7b) arranged in the backward direction of a lens advancing axis (A).

1. A method of controllably moving an intraocular lens, including an optic and at least one loop haptic, in a first direction through an inserter with a plunger that has an elongate rod and first and second longitudinally spaced portions which are formed from the same material, the method comprising the step of: after the intraocular lens has been positioned such that the optic is folded substantially in half and the loop haptic extends from the optic in a second direction that is substantially opposite of the first direction, initially engaging a single part of the loop haptic and then applying a pushing force to the loop haptic with the plunger without applying a pushing force to the optic; andafter applying the pushing force to the loop haptic with the plunger without applying the pushing force to the optic, simultaneously applying a pushing force in the first direction to the optic and to the loop haptic with the first and second longitudinally spaced portions of the plunger. 2. A method as claimed in claim 1, wherein the loop haptic includes a tip; andthe step of applying a pushing force to the loop haptic with the plunger comprises applying a pushing force to the loop haptic with the plunger, without applying a pushing force to the optic, that bends the tip in the first direction. 3. A method as claimed in claim 1, wherein the plunger defines a distal end; andthe step of simultaneously applying pushing force comprises simultaneously applying pushing force in the first direction to the optic with the distal end of the plunger and to the loop haptic with a surface that extends proximally from the distal end. 4. A method as claimed in claim 3, wherein the distal end of the plunger includes a surface which defines a plane that is substantially perpendicular to the first direction. 5. A method as claimed in claim 3, wherein the surface that extends proximally from the distal end comprises the surface of a groove. 6. A method as claimed in claim 5, wherein the groove extends proximally from the distal end of the plunger to an abutment. 7. A method as claimed in claim 1, wherein the inserter includes an inner surface, the method further comprising the step of: positioning first and second regions of the second portion of the plunger, which are spaced from one another in a direction perpendicular to the first direction, on opposite sides of the loop haptic and also between the loop haptic and first and second regions of the inserter inner surface that are spaced from one another in a direction perpendicular to the first direction. 8. A method as claimed in claim 1, wherein the inserter includes an inner surface and the optic and plunger are bifurcated by a common plane, the method further comprising the step of: positioning first and second plunger guides, which are spaced from one another in a direction perpendicular to the first direction, on opposite sides of the loop haptic, on opposite sides of the common plane, and also between the loop haptic and first and second portions of the inserter inner surface that are on opposite sides of the common plane. 9. A method of controllably moving an intraocular lens, including an optic and at least one haptic with a tip region, in a first direction through an inserter with a plunger, the method comprising the step of: after the intraocular lens has been positioned such that the optic is folded substantially in half and the haptic extends from the optic in a second direction that is substantially opposite of the first direction, applying a pushing force to only the haptic tip region in the first direction with the plunger such that the haptic bends in the first direction and the haptic tip region remains in contact with the plunger; andafter the haptic has been bent, and while the haptic tip region is in contact with the plunger and the haptic tip region is proximal of the optic, applying a pushing force to the optic and to the haptic tip region in the first direction such that the optic and haptic move together in the first direction. 10. A method as claimed in claim 9, wherein the plunger defines a distal end; andthe step of applying a pushing force to the optic and to the haptic tip region comprises applying the pushing force to the optic with the distal end of the plunger while the haptic tip region is bent and in contact with a surface that extends proximally from the distal end. 11. A method as claimed in claim 10, wherein the distal end of the plunger includes a surface which defines a plane that is substantially perpendicular to the first direction. 12. A method as claimed in claim 10, wherein the surface that extends proximally from the distal end comprises the surface of a groove. 13. A method as claimed in claim 12, wherein the groove extends proximally from the distal end of the plunger to an abutment. 14. A method as claimed in claim 9, wherein the inserter includes an inner surface, the method further comprising the step of: positioning first and second regions of the plunger, which are spaced from one another in a direction perpendicular to the first direction, on opposite sides of the haptic and also between the haptic and first and second regions of the inserter inner surface that are spaced from one another in a direction perpendicular to the first direction. 15. A method as claimed in claim 9, wherein the inserter includes an inner surface and the optic and plunger are bifurcated by a common plane, the method further comprises the step of: positioning first and second plunger guides, which are spaced from one another in a direction perpendicular to the first direction, on opposite sides of the haptic, on opposite sides of the common plane, and also between the haptic and first and second portions of the inserter inner surface on opposite sides of the common plane.
