Problems solved by technology

If the injector stem is not reprocessed (i.e., cleaned) to remove the accumulated viscoelastic material, the material may contaminate later stage patients undergoing cataract surgery using the same device and complications will be introduced

Embodiment Construction

[0021] Figures 1A-1C A device 10 for injecting an intraocular lens (IOL) into the anterior capsule of the eye is shown. IOL injection device 10 includes a tubular housing 12 that includes a first block 14 and a second block 16 . The first module 14 is disposed at the front end 18 of the housing 12 and the second module 16 is disposed at the rear of the first module 14 , eg, at the rear end 20 of the housing 12 .

[0022] Modules 14, 16 are configured to house the various internal components of IOL injection device 10 therein. For example, modules 14 , 16 house injector rods 22 . More particularly, the modules 14 , 16 collectively define a channel 24 that extends from the second module 16 through the first module 14 to the front end 18 of the housing 12 . An injector rod 22 is disposed longitudinally within this channel 24 and is movable therealong.

[0023] The first module 14 is also configured to receive a lens cartridge module 26 at or near the forward end 18 of the ho...

Abstract

An intraocular lens (IOL) injection device is modularized to enable cleaning of internal components after surgery. The device includes first and second housing modules. These modules collectively define a passageway along which an injector rod moves between a retracted position and an extended position. The first module is further configured to accommodate a lens cartridge module. The cartridge module has disposed therein an IOL, in alignment with the passageway. Thus as the rod moves from the retracted position to the extended position, a front portion of the rod that is substantially surrounded by the first module in the retracted position moves into the cartridge module and displaces the IOL. This causes the front portion of the rod to accumulate on it viscoelastic substances. The first module, though, is configured to detach from the second module, to thereby expose the front portion of the rod in the retracted position for cleaning.

Description

technical field [0001] The present invention generally relates to an intraocular lens injection device for surgically injecting an intraocular lens into an eye, and in particular to an intraocular lens injection device which is modularized to allow cleaning of internal components after surgery. Background technique [0002] The human eye provides vision by transmitting light through a clear exterior called the cornea and focusing it on the retina via a lens to form an image. The quality of the focused image depends on many factors including the size and shape of the eye, and the transparency of the cornea and lens. When age or disease makes the lens less transparent, vision deteriorates because the amount of light that can travel to the retina is reduced. This defect in the lens of the eye is medically known as a cataract. The accepted treatment for the disease is surgical removal of the eye's natural lens and replacement of the lens function by an intraocular lens (IOL). ...
