An apparatus for eye surgery may comprise a nozzle having a delivery lumen, an implant bay coupled to the nozzle, and an implant disposed in the implant bay. The implant may comprise an optic body, a leading haptic, and a trailing haptic. In some examples, the implant may be an intraocular lens. The apparatus may further comprise an actuator comprising a housing and a plunger disposed within the housing and a leading splay arm operable to splay the leading haptic within the implant bay. The plunger can be operable to advance the optic body from the implant bay to the delivery lumen after the leading splay arm straightens the leading haptic.

Haptic management for delivery of intraocular implants

Apparatuses, systems, and methods for implanting an intraocular lens into an eye are described. For example, an intraocular lens injector may include a plunger and an injector body that includes an insertion depth guard and a nozzle extending therefrom. The insertion depth guard is disposed at a distal end of the injector body to limit a distance that the nozzle penetrates the eye. The intraocular lens injector may also include a biasing element configured to generate a counterforce to distal movement of the plunger through the injector rod. An example intraocular lens injector may include a biasing element to produce a counterforce that opposes advancement of the plunger through the injector body. The counterforce provides for a more continuous advancement of the plunger while reducing or substantially eliminating abrupt changes in the rate at which the plunger is advanced through the injector body.

Intraocular lens injector

Apparatuses, systems, and methods for implanting an intraocular lens into an eye are described. For example, an intraocular lens injector may include a passage formed in a distal end portion of the intraocular lens injector. The passage may define an interior surface, and a ramp may be formed on the interior surface so as to cause a leading haptic of an intraocular lens (IOL) being advanced through the passage to lift above a surface of an optic of the IOL to ensure proper folding of the IOL.

Systems, methods, and apparatuses for removably attaching a drive mechanism handpiece to an intraocular lens (IOL) cartridge that folds the IOL upon removal of a cap, are provided. The IOL cartridge comprises a nozzle and a housing comprising a slide. A compartment configured to receive an IOL is disposed within the housing. An interior portion of the slide is exposed to the compartment. The nozzle is in fluid communication with the compartment. The cap covers the nozzle and the slide. The cap is configured to expose the nozzle and advance the slide to fold the IOL upon removal of the cap.

Removable cap actuation for an intraocular lens cartridge

Various systems and techniques for inserting an intraocular lens are disclosed. In particular implementations, a system and a technique for inserting an intraocular lens may include the ability to move, in response to a force being applied in a first direction along a longitudinal axis, a first plunger tip along the longitudinal axis and into a delivery cartridge to fold an intraocular lens and move in a second direction along the longitudinal axis in response to the applied force being reduced. The system and the technique may also include the ability to engage a second plunger tip and move, in response to a force being applied in the first direction along the longitudinal axis, the second plunger tip along the longitudinal axis and into the delivery cartridge to insert the intraocular lens.

Systems and processes for inserting an intraocular lens

Systems, methods, and apparatuses for storing and/or shipping an intraocular lens (IOL) cartridge are provided. A system comprises a packaging comprising a passage. The IOL cartridge is removably disposed within the passage. The IOL cartridge comprises a nozzle and a compartment configured to receive an IOL. The nozzle is in fluid communication with the compartment. The IOL cartridge further comprises a dial configured to rotate upon withdrawal of the IOL cartridge from the passage, wherein an inner surface of the dial is exposed to the compartment. The dial is configured to fold the IOL and release the IOL cartridge from the packaging upon rotation of the dial.

Packaging-assisted actuation for an intraocular lens cartridge

Systems, methods, and apparatuses for storing and/or shipping an intraocular lens (IOL) cartridge are provided. A system comprises the IOL cartridge. The IOL cartridge comprises a nozzle and a compartment comprising an IOL. The nozzle is in fluid communication with the compartment. The IOL cartridge further comprises a dial disposed adjacent to the compartment, wherein an inner surface of the dial is exposed to the compartment. The dial is configured to fold the IOL upon rotation of the dial. The IOL cartridge further comprises a plunger case in fluid communication with the compartment, wherein a plunger is movably disposed within the plunger case. The IOL cartridge is configured to removably attach to a handpiece. The system further comprises a packaging comprising a base, wherein the IOL cartridge is disposed within the base; a first removable cover configured to cover a first portion of the IOL cartridge; and a second removable cover configured to cover a second portion of the IOL cartridge, wherein the second removable cover is locked in place by the dial when the dial is in a non-rotated position.

Packaging-integrated manually actuated intraocular lens cartridge

Systems, methods, and apparatuses for inserting an intraocular lens (IOL) into an eye, are provided. The apparatus comprises an IOL cartridge comprising a nozzle, a compartment, a plunger, and a plunger case. The nozzle is in fluid communication with the compartment, and the plunger case is in fluid communication with the compartment. The plunger is disposed within the plunger case. The plunger case includes flexible members extending from an outer surface of the plunger case. The IOL cartridge is configured to removably attach to a handpiece.

Push mechanism for interfacing a drive mechanism handpiece with an introacular lens cartridge

Systems, methods, and apparatuses for inserting an intraocular lens (IOL) into an eye, are provided. An apparatus comprises an IOL cartridge comprising a nozzle, a compartment, and a plunger case. The nozzle is in fluid communication with the compartment, and the plunger case is in fluid communication with the compartment. The plunger is disposed within the plunger case. The plunger case is configured to removably attach to a handpiece.

Push and twist mechanism for interfacing a drive mechanism handpiece with an intraocular lens cartridge

Systems, methods, and apparatuses for removably attaching a drive mechanism handpiece to an intraocular lens (IOL) cartridge that folds the IOL upon retraction of a cap, are provided. The IOL cartridge comprises a nozzle and a compartment configured to receive an IOL. The nozzle is in fluid communication with the compartment. The IOL cartridge also includes a retractable cap that covers the nozzle and the compartment. The retractable cap is configured to expose the nozzle and fold the IOL upon retraction of the retractable cap. The IOL cartridge may also include a plunger case that is in fluid communication with the compartment, wherein a plunger is movably disposed within the plunger case.

Retractable cap actuation for an intraocular lens cartridge

An intraocular lens (IOL) folding device is described.
