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.

A male form is configured as an attachment element for an injector for implanting an intraocular lens in an eye. The male form includes an elongate carrier part and a front part that is arranged at one end of the elongate carrier part. The front part has a front side and is made of an elastically deformable material, the deformable material being compressible at least in the direction of a longitudinal axis (A) of the male form. The front side includes a first peripheral side, an opposite second peripheral side, and at least one elongate indentation, which is formed in the front part and which is open at the front side. The indentation extends between the two peripheral sides and opens out at the peripheral sides. An injector for implanting an intraocular lens having the male form is also disclosed.

Intraocular lens injectors described herein may include a symmetrical arranged storage compartment, nozzle passage, and plunger tip in order to symmetrically fold and provide symmetrical loading to an intraocular lens during advancement and delivery so as to avoid rotation of the intraocular lens about longitudinal, vertical, and/or lateral axes during advancement and/or delivery of the intraocular lens.

An intraocular lens insertion apparatus which allows the intraocular lens to behave more stably. The intraocular lens insertion apparatus includes a substantially tubular apparatus body which has, at a tip end thereof, an insertion tube part for inserting an intraocular lens in a folded state into an eye, the intraocular lens having a lens body and a support, a storage which stores the intraocular lens, and an extruding member which moves the intraocular lens in the insertion tube part by pushing the intraocular lens, and the extruding member has a tip end part having a first protrusion protruding to one side in a left-right direction and a second protrusion protruding to the other side in the left-right direction.

An IOL injector having a lever-driven plunger mechanism is described.

An injection system for an intraocular lens (IOL) utilizes a folding device for the IOL. The folding device comprises a pair of co-acting winglets pivotable between an open position and a closed position, and together defining a hinge axis and a receptacle for the IOL. Each winglet has an outwardly extending, unitary leg portion defining a base plane that includes the hinge axis and a motion limiting protuberance on each said leg portion extending from the base plane. The base planes are situated at an angle relative to one another and the protuberances abut one another when the winglets are in the open position. The base planes merge into a single plane when the winglets are in the closed position.

An intraocular lens inserter can include a drive device with controllable advance motion. The drive device may include an actuator device and an energy device. The actuator device may include a piston rod that uses the advance motion to push an intraocular lens from a cartridge for insertion into an eye of an animal. The energy device may act upon the actuator device to generate the advance motion. The actuator device may include a dampening medium to control the advance motion, such as by controllably dampening the advance motion.

There is provided an intraocular ring injector which allows an operator to stably and normally house the intraocular ring in the intraocular ring injector, which is an intraocular ring injector 20 with a container configured so that an intraocular ring injector 10 is housed in a container 4, for injecting an intraocular ring C into an eye for retaining a shape of a lens capsule, the intraocular ring injector comprising: a hollow body 1 having a hollow part in which the intraocular ring C is housed; a plunger 2 that moves through an inside of the hollow body 1 in an axial direction of the hollow body 1; and a pushing member 3 that pushes out the intraocular ring C by moving together with the plunger 2 through the inside of the hollow body 1 and toward front part of the hollow body 1 in the axial direction, wherein the container 4 has a moving mechanism of moving the hollow body 1 and the plunger 2 relatively in the axial direction, while housing the intraocular ring injector 10 in the container 4.

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.
