Problems solved by technology

This can cause excessive force on the plunger tip and the IOL, resulting in possible damage to the IOL and / or uncontrolled release of the IOL from the end of the lumen
In addition, the force of the plunger tip may cause the IOL to twist and / or rotate as it moves through the inserter, such that the IOL and plunger tip and / or the inserter lumen may grow uncontrollably leading to damage to the IOL

Embodiment Construction

[0055] Referring now to the drawings, there is shown a preferred embodiment of the syringe of the present invention, indicated generally at 10 . In a first broad aspect, the invention comprises a pre-loaded syringe for injecting an IOL into an eye. The term "preloaded" as used herein refers to the packaging of the syringe body 12 with the IOL, wherein the IOL 30 is held by the retainer 40 in the storage position on the syringe body (see also Figure 11 and 12 ). In an alternative embodiment of the invention, the syringe is "partially preloaded" in the sense that the IOL 30 and retainer 40 are connected and packaged together, but not yet connected to the syringe body 12 (see also Figure 10 ). In this alternative embodiment, the physician or nurse installs the retainer and IOL onto the syringe body at the time of the procedure.

[0056] Syringe body 12 includes a longitudinal lumen 14 extending from a proximal end 16 to a distal end 18 thereof. The lumen may take any desir...

Abstract

A preloaded intraocular lens injection device includes a retainer for releasably holding an IOL in an unstressed state. The retainer and IOL are removably attached to an injector body and are sealed in the same package for delivery to a surgeon. In an alternate embodiment, the retainer and IOL are coupled together and sealed in one package and the injector body is sealed in a separate package with the surgeon attaching the retainer to the injector body at the time of surgery. To deliver the IOL through the injector body, the retainer is removed from the injector body causing the IOL to release from the retainer and become located in an unstressed state in the injector body. A compressor is moved to the closed position to compress the IOL, the injector tip is inserted through a small incision in an eye and a plunger is advanced to push the IOL through and out the injector body tip and into an eye.

Description

[0001] related application [0002] This application is a continuation-in-part of application Serial No. 10 / 681,785 filed August 28,2003. technical field [0003] The present invention relates to ophthalmic surgical devices and methods. In particular, the present invention relates to devices and methods for inserting an intraocular lens (IOL) into an eye, wherein the IOL may be preloaded in a syringe and packaged with the syringe in a conventional manner. Background technique [0004] An IOL is an artificial lens used to replace the natural lens of the eye when it has cataracts or other diseases. An IOL is sometimes implanted in the eye to correct a refractive error of the eye, in which case the natural lens remains in the eye along with the implanted IOL. The IOL can be placed in either the posterior or anterior chamber of the eye. IOLs are formed in a wide variety of shapes and materials. Some common IOL styles include so-called open-loop haptic IOLs, which come in thr...
