摘要： There is provided an intraocular lens injector including: a hollow body composed of an injector main body 5 having a lens installing portion on which an intraocular lens is installed, and an injection tube 7 attached to a tip part of the injector body 5; a rotary member 8 having a first threaded portion formed thereon and attached to a rear end part of the injector body 5 that constitutes the hollow body, rotatably around an axis of the hollow body; a plunger 9 having a second threaded portion 9c formed thereon, and configured to move through the hollow body in an axial direction of the hollow body; a rod 10 configured to push out the intraocular lens from the lens installing portion by moving through the hollow body in the axial direction of the hollow body together with the plunger 9, wherein a tip side of the plunger 9 is injected into the hollow body in a state in which the first threaded portion and the second threaded portion 9c are meshed with each other, and a rear end side of the plunger 9 is disposed in a state of protruding backward of the rotary member 8.

摘要： There is provided an intraocular lens injector capable of smoothly performing an operation when an intraocular lens is injected, the intraocular lens injector, including:



a hollow body 5 having a lens setting portion 11 on which an intraocular lens 4 is set;
a plunger 9 that moves through an inside of the hollow body 5 in an axial direction of the hollow body 5;
a pushing member 10 that pushes out the intraocular lens 4 from the lens setting portion 11 by moving together with the plunger 9, through the inside of the hollow body 5, and toward front part of the axial direction of the hollow body 5;
a first flange 14a protruded from an outer circumferential surface of the hollow body 5; and
a second flange 14b arranged on a rear end side with respect to the first flange and protruded from the outer circumferential surface of the hollow body 5;
wherein the hollow body 5 is configured so that a shape on the A direction side toward a center of gravity of the hollow body 5 in which the first flange 14a is arranged from a center O of the hollow body 5, and a shape on the A′ direction side which is the opposite direction to the A direction, are non-symmetrical, when viewed from the axial direction, and
the second flange 14b is configured to protrude toward at least the A′ direction, and
the first flange 14a is configured not to protrude toward the A′ direction, or configured so that a protruding distance of the first flange 14a toward the A′ direction is smaller than a protruding distance Ha of the first flange toward the A direction and smaller than a protruding distance Hb of the second flange toward the A′ direction.
