Artificial Iris



Regardless of partial or complete aniridia – the world's first artificial iris prothesis provides a solution to restore vision not only optically but also aesthetically: 

The ArtificialIris , has finally come up with a solution that offers a genuine improvement in the quality of life for people with aniridia.


PRESENT IMPLANTS

Iris implants consist of rigid materials (e.g. a material similar to plastic) and are manufactured in only a few standard colors.

An exact, aesthetical replica of the patient’s individual eye color is not offered. With traditional iris implants the natural iris structure is not reproduced either. Furthermore, implantation usually requires a comparatively larger incision (approx. 10 mm versus 3 mm for the ArtificialIris).

The bigger the incision the more complicated the surgery and the higher the risk of infection. Smaller incisions also reduce permanent astigmatism that can be caused by the healing process.


ARTIFICIALIRIS – THE INNOVATIVE SOLUTION

The ArtificialIris was developed by HumanOptics (former Dr. Schmidt Intraocularlinsen) in close collaboration with Prof. Dr. med. Hans-Reinhard Koch (Bonn, Germany).

Just looking at Germany about 1.000 patients suffering from partial or complete aniridia can benefit from the artificial iris prothesis annually (incidence rate 1:80.000). This new implant offers them a completely new perspective.

Implants currently available on the market are manufactured only in a few standard colors. The ArtificialIris, however, matches the patient’s original iris color. Only like this a natural look can be achieved.

Another innovation: the new implant offers optimal optical features and is foldable, only a small incision is required for insertion. The ArtificialIris reduces glare and at the same time increases depth of focus and contrast sensitivity. When treating partial aniridia it is even possible to just use a segment of the ArtificialIris in order to preserve the remnants of the natural iris.


TREATMENT PLAN

Patients requiring this treatment need to have photos taken of the existing healthy eye and of the defective iris of the fellow eye. The  experts use these photos in order to exactly transpose the color pattern to the implant (as the target color for production). If the iris is missing in both eyes, the patient can send a picture of their liking as target color for production.


IMPLANTATION OF AN ARTIFICIALIRIS

The implantation of this device normally takes about 20 minutes and is done under local anaesthesia. The folded or rolled silicone disc is inserted through a small incision at the corneal rim, then unfolded in the eye and fixed in place.

A more complex implantation, for example involving additional suturing in order to fix the partial prosthesis to the iris remnant, can take up to one hour (and more) and might require a larger incision.

As soon as the eye patch is removed after surgery, the result is immediately visible. The new iris with the fixed pupil can now function as an aperture. The glare decreases significantly and the depth of focus improves. Contrasts between light and dark objects are easily distinguished again and the eye has received a dramatic cosmetic improvement.


EXPERIENCE WITH THE ARTIFICIALIRIS

Prof. Dr. med. Hans-Reinhard Koch has been significantly involved in the development of new products. His experience with the artificial iris prothesis has been very positive:

"The ArtificialIris is an important step in the treatment of aniridia or severe iris defects. The functional and aesthetical features and the optimal biological compatibility meet the demands of an ideal iris substitute for the first time. My patients tell me that their quality of life has improved considerably." (Prof. H.-R. Koch)

The ArtificialIris has already been implanted very successfully in more than 1000 eyes.
