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. 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.
INTRAOCULAR LENS INJECTOR APPARATUS
An injector for injecting an IOL into an eye, comprising an injector body having a lumen wall defining a lumen, a plunger having a longitudinal axis and a soft tip at a distal end of the plunger. The soft tip having a concave distal surface. In a plane including the longitudinal axis, the plane being perpendicular to an IOL optical axis when the IOL is located at a staging area of the injector body, the concave distal surface extending in a direction at a non-perpendicular angle relative to the longitudinal axis. The concave distal surface may be oval-shaped in a plane perpendicular to the direction, and the concave distal surface has no curvature along the direction.
Injector having a handle for carrying along a front and a rear displacement mechanism
An injector for inserting an intraocular lens into the capsular bag of an eye has an injector body; a plunger for displacing the lens out of the injector in an insertion direction, with the lens having an optic body with an optical axis and a rear and a front haptic; a rear mechanism for displacing an optic body distant longitudinal end of the rear haptic onto the optic body via a displacement of the plunger; a front mechanism for displacing an optic body distant longitudinal end of the front haptic along a front trajectory having a front component parallel to the optical axis; and a handle operable from outside of the injector and which has a first catch coupled to the plunger to carry along the plunger in the insertion direction via a longitudinal displacement of the handle and has a second catch to carry along the front displacement mechanism.
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.
Lens delivery system
Delivery devices for delivering an ophthalmic device into an eye. In some embodiments the delivery devices are adapted to deliver an intraocular lens into an eye.
Ocular implant insertion apparatus and methods
An ocular implant insertion apparatus that includes a plunger driver that is not manually powered and ocular implant insertion methods. There are a variety of instances where an ocular implant is inserted into the anterior chamber, posterior chamber, cornea, vitreous space and/or other portion of an eye. Exemplary ocular implants include, but are not limited to, lenses, capsular tension rings, ocular prosthesis and lamellar transplants.
Intraocular lens insertion device
Accordingly, embodiments of the present invention provide an IOL insertion device that facilitates the injection of the IOL in a controlled manner. The insertion device includes a front modular portion and an injector. The modular portion may be preloaded with an IOL and coupled with the injector. The injector includes a distal portion, a body, and a plunger. The distal portion includes a front seal which has a longitudinal bore at the center, through which a distal portion of the plunger passes. The plunger tip is tapered. The plunger also includes a sealing element situated between its distal portion and its proximal portion. The sealing element includes a small aperture through which a fluid, such as a viscoelastic or a balanced salt solution (BSS) and the like, may pass toward the proximal end of the body when the plunger advances distally. As the fluid passes through the small aperture on the sealing element on the plunger, a constant speed and force is maintained as the IOL is ejected into the eye.
INTRAOCULAR LENS INJECTOR
There is provided an intraocular lens injector for injecting an intraocular lens into an eye, including: an injector main body 5; an injection tube 7 attached to a tip part of the injector main body 5 and having a nozzle portion 7b; and an attachment member 16 having a protruding surface disposed in a state of protruding to outside from an outer circumferential surface of the nozzle portion 7b, wherein the attachment member 16 has an engaging portion 16b engaged with a sleeve portion 16a and is configured to be movable with respect to the injection tubed 7.
OPHTHALMOSURGICAL INJECTOR SYSTEM
An ophthalmosurgical injector system includes an injector, which has a handpiece, a plunger, and a dispensing device; an intraocular lens, which has an optic body and two C-shaped haptic arms protruding therefrom; and a cartridge, in which the intraocular lens is received. The dispensing device has an inlet opening at the proximal end and an outlet opening at the distal end. When the plunger is moved forward, the intraocular lens is conveyed from the cartridge through the inlet opening to the outlet opening of the dispensing device. When the intraocular lens is held in the cartridge in a compressed and preloaded state, a subregion of each of the haptic arms bears on and covers the optic body. In a plan view, the optic body of the preloaded intraocular lens has a circular surface area with a diameter of at least 4.0 mm that is not covered by the haptic arms.
MALE FORM AS AN ATTACHMENT ELEMENT FOR AN INJECTOR, AND INJECTOR FOR IMPLANTING AN INTRAOCULAR LENS IN AN EYE
A male form is configured as an attachment element for an injector for implanting an intraocular lens in an eye. The male form includes an elongate carrier part and a front part that is arranged at one end of the elongate carrier part. The front part has a front side and is made of an elastically deformable material, the deformable material being compressible at least in the direction of a longitudinal axis (A) of the male form. The front side includes a first peripheral side, an opposite second peripheral side, and at least one elongate indentation, which is formed in the front part and which is open at the front side. The indentation extends between the two peripheral sides and opens out at the peripheral sides. An injector for implanting an intraocular lens having the male form is also disclosed.
