Systems and processes for inserting an intraocular lens
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.
Injector for intraocular lenses
An intraocular lens implantation injector has a base body and an elongated actuation element projecting into a base body rear section and movably guided along an actuation axis. Actuation element movement is generated selectively by axial push actuation or by a screw actuation about the axis. The actuation element features an external thread at least on one section. At least one spring arm arranged at the base body has an inner surface thread engagement structure facing the external thread. A switch element, interacting with the spring arm, is rotatably or displaceably arranged on the base body. The switch element interacts with the spring arm via an operative contact. At least one switch element inner surface and/or spring arm outer surface involved in the operative contact is angularly inclined to the axis. Switch element rotation/displacement generates spring arm elastic deformation towards/away from the axis, thereby engaging/disengaging the thread engagement structure.

Intraocular lens (IOL) injector and method of use thereof
The present invention provides a device and method for inserting an IOL into an eye of a patient. The IOL injector is configured to automatically load an IOL into the injector by folding and aligning the IOL into a lens cartridge of the injector without manual manipulation of the IOL by the physician during the procedure. The injector is configured to properly orient and align the IOL within the injector and maintain proper alignment throughout delivery of the IOL to the eye of a patient and thereby ensuring that the IOL is properly positioned and oriented at a predetermined location in the eye.
INTRAOCULAR LENS DELIVERY DEVICE AND METHOD OF USE
An IOL delivery device which has a macro movement actuator which is actuateable to move an IOL into position in the device for the IOL to be delivered, and a micro movement actuator comprising at least one pivotable member which is pivotable to deliver the IOL to the eye. The pivotable member may comprise one or more wheels that are rotatable using one's finger.
Systems and methods for intraocular lens deployment
An intraocular lens (IOL) insertion apparatus may include a handpiece body having a distal tip and a deployment chamber located at a distal end of the handpiece body. The deployment chamber is sized and shaped to hold a folded IOL. The IOL insertion apparatus further includes a deployment system disposed within the handpiece body. The deployment system may include a deployment carriage movable between a first position and a second position within the handpiece body. The deployment carriage may include a biasing element that biases the deployment carriage in a distal direction toward the distal tip. The deployment system may further include a deployment trigger that prevents distal movement of the deployment carriage unless pressed and a deployment plunger having a proximal end secured to the deployment carriage and a distal end to engage the folded IOL.
Intraocular lens injector and intraocular lens injection device
An intraocular lens injector (1) includes: a hollow body having an injector body (5) provided with a lens placement portion (11) on which an intraocular lens is placed, and a screw member (8) with a first threaded portion (8b) formed thereon and connected to a rear end portion of the injector body (5), and rotatable around an axis of the injector body (5) without moving in an axial direction of the injector body; and a moving member (9, 10) having a second threaded portion (9c) that engages with the first threaded portion (8b) from an initial state before use, and configured to release the intraocular lens from a tip of an injection tube 7 by moving in an axial direction of the injector body (5) independently from the screw member (8) due to an engagement of the first threaded portion (8b) and the second threaded portion (9c), during a rotating operation of the screw member (8).
INTRAOCULAR LENS INSERTION SYSTEM
A system for delivering an intraocular lens (IOL) is disclosed, including: a handpiece including a barrel defining an elongate passage, a pushrod disposed inside the elongate passage, and a plunger coupled to the pushrod; and a delivery unit coupled to a first end of the barrel, the delivery unit including a delivery tube and a lens holder coupled to the delivery tube, the lens holder including a lead haptic shelf arranged to receive a lead haptic of an IOL that is contained inside the lens holder, wherein the lead haptic shelf is configured to fold the lead haptic of the IOL over a body of the IOL while permitting the IOL to travel under the lead haptic shelf when the IOL is displaced from the lens holder to the delivery tube by the pushrod during delivery of the IOL into a patient's eye.
DELIVERY SYSTEM
Disclosed is a delivery system for an ocular implant and a method of delivering an ocular implant to an eye using a delivery system. The delivery system includes a delivery tube having a delivery end and a control end, and the delivery end comprises an opening. A delivery device is configured to fit at least partially within the delivery tube. The delivery device configured to contact the ocular implant and control the position of the ocular implant within the delivery tube. The delivery system includes a fluid inlet nozzle that is configured to inject fluid into the delivery tube between the control end and the ocular implant. The delivery system is configured such that the injected fluid flows around the sides of the ocular implant and out from the delivery end of the delivery tube.
