Abstract:
1. An intraocular-lens insertion device for deforming a deformable intraocular lens into a smaller size and inserting the intraocular lens into an eye, comprising: a device body; an insertion tube attached to a front end of the device body and adapted to be inserted into the eye; a push rod axially movable through the device body and the insertion tube and adapted to insert the intraocular lens into the eye when advanced; a push-out mechanism for advancing the push rod; a stress release structure provided on the insertion tube and adapted to release stress of the intraocular lens produced due to deformation thereof; and a frictional-resistance increasing structure provided on an inner surface of the insertion tube to be located in the vicinity of the stress release structure, the frictional-resistance increasing structure increasing frictional resistance between the inner surface of the insertion tube and the intraocular lens, said frictional-resistance increasing structure comprising a roughened surface which at least partially covers the inner surface of the insertion tube along the circumferential direction.
