An injector for ejecting an intraocular lens into an eye, comprises a longitudinal injector body, in which an injector piston rod can be guided in an axially displaceable manner, an injector nozzle at a front end of the injector body, in the direction of which the injector piston rod can be displaced, a displacement mechanism for pushing the injector piston rod forwards, and an actuating element for the manual actuation of the displacement mechanism.

The displacement mechanism includes a transmission mechanism, by means of which the actuating element and the injector piston rod can be placed in an articulated driving connection, and an operating region for the actuation of the actuating element is formed at a longitudinal side of the injector body.

An intraocular lens is disclosed that includes an optic body with a projection extending radially outwards from a peripheral surface of the optic body. The projection comprises a haptic contact surface facing radially outward, wherein the entire haptic contact surface is a flat surface. A haptic having a free distal end and a proximal portion is secured to the projection along the haptic contact surface, wherein the projection and the proximal portion interface at a butt joint without the haptic extending into the projection and without the projection extending into the haptic. The haptic also includes a haptic fluid chamber.

Provided is an intraocular lens exchanger for moving a foldable intraocular lens (IOL), the intraocular lens exchanger including: an outer tube having a first passage formed in a forward/rearward direction; an inner tube disposed to be movable along the first passage and having a second passage formed in the forward/rearward direction; and a variable tube extending from a front end of the inner tube to form a variable passage connected to the second passage, in which the variable tube has an extension part having a width that increases forward in an unconstrained state in which the variable tube is not positioned in the first passage, and the extension part is provided to be elastically deformed when the unconstrained state changes to a constrained state in which at least a part of the extension part is received in the first passage.

An intraocular lens inserter can include an energy storage portion, an actuator portion, and a lens support portion. The energy storage portion can include a compressible energy storage device, such as a compressible fluid, springs, and other devices. The inserter can include an actuator portion operating with a substantially incompressible fluid, such as liquids or other noncompressible fluids. The actuator can be configured to provide an operator with control over the release of energy from the energy storage portion so as to move a plunger for the discharge of a lens from an intraocular lens cartridge.

Provided is an injector assembly, comprising: —an injector, which has a plunger and a cannula and is designed to move an intraocular lens through the cannula by means of a translational motion of the plunger; —a magnetic coupling; and —a drive unit, which has a first coupling half of the magnetic coupling, a motor, which is designed to drive the first coupling half into a first rotational motion, and a housing, within which the first coupling half and the motor are encapsulated and which has an annular housing portion, which delimits a channel having a circular cross-section. The injector has a second coupling half of the magnetic coupling, and the injector and the second coupling half are arranged in the channel. The first coupling half is arranged around the annular housing portion and is thus designed to perform the first rotational motion around the annular housing portion and thus to drive the second coupling half into a second rotational motion by means of a magnetic field of the magnetic coupling, which magnetic field penetrates the annular housing portion. The injector is designed to convert the second rotational motion into the translational motion of the plunger.

An intraocular lens insertion apparatus includes a distal end member which is inserted through an incision in an eyeball of a patient, an opening member provided for the distal end member through which an intraocular lens is ejected, and an indicating means provided for the distal end member. The indicating means is used for indicating that an entire part of the opening member is inside a cornea of the eyeball or inside a sclerocornea of the eyeball with respect to an external flap of the incision.

The present disclosure is directed to devices, systems, and methods directed to mounting a plunger tip to a plunger of an IOL injection device. A plunger tip wrench that is operable to releasably retain a plunger tip may be coupled to a holder extending from an end of the IOL injection device to align the plunger tip with the plunger of the IOL injection device. In some instances, the IOL injection device may include a motor and use a back electromotive force (EMF) of the motor to detect a position of the plunger as it is extended to engage the plunger tip. The plunger tip may be positioned relative to the plunger such that the plunger will engage the plunger tip within the entire range of a negative error position and a positive error position.

An intraocular lens storage system for storing an intraocular lens. The intraocular lens storage system includes a storage container for storing the intraocular lens and an actuable transfer device, which is arranged in the storage container, with an intraocular lens receiver to receive the intraocular lens. The transfer device is movable between an intraocular lens storage position for storing the intraocular lens in the storage container and an intraocular lens transfer position to transfer the intraocular lens to an injection device.

Canisters are provided that include a cylindrical body and a cap welded to the body to define a cavity filled with carbon dioxide or other fluid. The canisters may be loaded into a medical device, e.g., to provide an energy source for operating the device. Methods for making such canisters are also provided.

A magnetically coupled drive module for delivering an implant to an eye. An implant may be stored, advanced, and delivered to an eye using a powered drive module. The drive module may be decoupled and sterilized for reuse.
