Problems solved by technology

Due to the delicate nature of the IOL, there is a risk that the nurse and / or surgeon will inadvertently damage the IOL and / or incorrectly load the IOL into the infusion device leading to implant failure
Handling and / or loading the IOL directly into the injector by a nurse and / or surgeon is therefore not ideal

Embodiment Construction

[0031] First, in a broad sense, the present invention includes a pre-loaded injection device for injecting IOLs into the eye. As used herein, the term "preloaded" means that the packaging component of the injection device includes the IOL provided therein. Direct manipulation and loading of the IOL into the injection device are therefore unnecessary.

[0032] in Figure 1a with 1b You can see the steps of assembling the components of the injection device 10 in Figure 2a with 2b The fully assembled injection device 10 can be seen in it. Some individual components of the injection device are shown in more detail in the remaining figures. The injection device 10 includes a proximal body portion 12, a distal nozzle portion 14 and a reciprocating member 16, which are packaged separately and then connected together at the time of surgery, so that the device is ready for delivery of the IOL 30 and Into the eyes of the patient (see Figure 2b ). The IOL 30 is pre-loaded into the recip...

Abstract

Apparatus and method for preloading an intraocular lens in a component of an injector device. The intraocular lens is positioned in a shuttle which is positioned and sealed in a vial of storage solution. At the time of use, the surgeon opens the vial and attaches a distal nozzle section to the shuttle located in the vial. The distal nozzle section and shuttle are then attached to a proximal body section having a plunger. The plunger is advanced to express the IOL from the distal tip of the distal nozzle section.

Description

Technical field [0001] The present invention relates to ophthalmic medical devices and methods. More specifically, the present invention relates to a device and method for injecting an intraocular lens (IOL) into the eye, where the IOL can be conveniently pre-loaded in the injector device and packaged with it. Background technique [0002] IOL is an intraocular lens used to replace the natural lens of the eye when cataracts or other diseases occur in the natural lens. IOLs are sometimes also implanted in the eye to correct the refractive index error of the eye, in which case the natural lens can remain in the eye together with the implanted IOL. IOL can be placed in the anterior or posterior chamber of the eye. IOL can use various structures and materials. Some common IOL styles include: the so-called open loop haptics, which include: a three-piece type with an optical element and two haptics mounted on and extending from the optical element; a single-piece type in which the o...
