An intraocular lens (IOL) insertion apparatus includes a handpiece body having a distal tip and a proximal section. The IOL insertion apparatus also includes a folding chamber located within the handpiece body, the folding chamber shaped to fold an IOL advancing through the folding chamber. The IOL insertion apparatus also includes an advancement system. The advancement system includes an advancement carriage movable between a first position and a second position within the handpiece body. The advancement carriage includes a spring system biasing the advancement carriage in a distal direction toward the second position and a dampening system to dampen motion of the advancement carriage. The advancement system further includes an elongated advancement plunger that includes a distal end to advance the IOL through the folding chamber and a proximal end connected to the advancement carriage.

Modular IOL systems including a base and a lens, wherein the lens includes fixed and actuatable tabs for connection to the base. The modular IOL allows for the lens to be adjusted or exchanged while leaving the base in place, either intra-operatively or post-operatively. Drug delivery capabilities and/or sensing capabilities may be incorporated into the base. Injector devices may be used to facilitate placement of the base and the lens sequentially or simultaneously into the eye.

An intraocular lens (IOL) injectors and associated methods are described. The IOL injectors may include a collapsible portion configured to reduce the length of the IOL injector when the collapsible portion is altered from an uncollapsed configuration to a collapsed configuration. In some instances, an IOL may be advanced from a storage location to a dwell location when the collapsible portion is altered from the uncollapsed configuration to the collapsed configuration. The IOL injectors may also include a combination push and screw drive.

An IOL injector having an automatic plunger advancement driver is described. In addition, an IOL injector having a spring-assisted driving mechanism and a spring damping mechanism is described.

An IOL injector having a collapsible mechanism and/or a lever-driven rack and pinion is described.

An intraocular lens injector with controlled insertion has in a pen-like casing (1) a rear part including an actuator (18) connected anteriorly to an insertion rod (19) for inserting the intraocular lens (IOL) in a patient's eye, and an intermediate handle portion (6) on which a device for controlling the advancement of the push rod (9) is provided. The push rod (9) has a prismatic shape, and is provided with a toothed rack (24), and the device for controlling the advancement of the push rod (9) engages and disengages with respect to the toothed rack (24) co-operating as an elastic return element abutting the pen-like casing (1) to control the advancement of the push rod (9).

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.

An injector for ejecting an intraocular lens for injecting the latter into an eye or for implanting a corneal endothelial tissue, comprising an elongate injector body which has a piston rod passage and in which an injector piston rod having a screw thread is guided in a longitudinally displaceable manner. The injector is provided with two operating modes for the displacement of the injector piston rod and is able to be switched between the modes. The first operating mode defines an ejection operation and the second operating mode defines a screwing operation. The injector body has at least one retractable and deployable wing grip, wherein the operating mode is set to ejection operation by the deployed position and the operating mode is set to screwing operation by the retracted position. The injector piston rod comprises a stop element.
