  • INTRAOCULAR LENS INSERTION DEVICE
    Publication number: 20120221102
    Abstract: An intraocular lens insertion device having a novel configuration, capable of more accurately arranging front and back surfaces of an intraocular lens in a proper direction. The intraocular lens insertion device is adapted in such a manner that the intraocular lens is set on a stage in a state placed flat with a pair of haptics extended facing front and back sides in a movement direction by a plunger. Also, an interfering acting part is provided to an insertion tube part, and the interfering acting part interferes with the haptic, which is extended facing the front side in the movement direction of the intraocular lens moved by the plunger, to apply on the haptic an external force toward the back side in the movement direction. Thus, the interfering acting part curves and deforms the haptic to a side approaching an optical portion.
