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.

Systems, methods, and devices for inserting an intraocular lens (IOL) assembly into an eye may be provided. A device for delivery of the IOL into the eye may include a housing; a nozzle operatively coupled to the housing; a first cylinder movably disposed within the housing; a second cylinder movably disposed within the housing, wherein the second cylinder is in fluid communication with the first cylinder; a plunger at least partially and movably disposed within the first cylinder; and a shaft movably disposed within the second cylinder, wherein the shaft is configured to move toward the lens component.

Intraocular lens delivery devices and methods of use.

Intraocular lens delivery devices and methods of use.

An intraocular lens (IOL) insertion apparatus may include a hand piece body having a distal tip, an IOL folding chamber, and IOL a dwell position, and a telescoping plunger having a first plunger portion and a second plunger portion. The first plunger portion and second plunger portion may be arranged to simultaneously advance through a first portion of a displacement of the telescoping plunger, and one of the first and second plunger portions may be arranged to advance through a second portion of the displacement of the telescoping plunger.

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.

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.

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.

An apparatus for eye surgery may comprise a nozzle having a delivery lumen, an implant bay coupled to the nozzle, an implant disposed in the implant bay, and an actuator coupled to the implant bay. The actuator may comprise a housing, a plunger disposed within the housing, a bore through the plunger, a first coupling proximate to a first end of the plunger, and a second coupling integral to the housing. The bore may be fluidly coupled to the implant bay. The first coupling may be configured to receive a hydraulic driver and fluidly couple a working fluid in the hydraulic driver to the bore. A portion of the plunger may be slidingly disposed through the second coupling. In some embodiments, the second coupling may be configured to retain a drive coupling of the hydraulic driver in a fixed position relative to the housing.
