The Fitting Process

There are several methods of fitting an artificial eye. Many years ago stock eyes, or (ready-made eyes), were fit by trying different shapes into the socket until a satisfactory lid opening was achieved.

This method required the fitter to have a large selection of stock eyes on hand to simulate the patient's iris color and fill the shape requirements with the iris in the right position. Fitting stock eyes was not, and is not, considered the most exacting method of fitting because of the guesswork involved.

In the United States stock eyes are rarely fit any more because of the problems they can cause, and Board Certified Ocularists, (B.C.O.), do not use stock eyes because of the inherent inaccuracies sighted.

The custom-made prosthesis, as the name implies, is made from a direct model of the socket. During the first fitting appointment, about eight weeks following surgery, an impression is usually taken, if possible, of the socket to provide maximum conformation and contact to ensure a proper fit.  The material used is similar to that used for taking dental impressions and the process takes only a few minutes.  This procedure is not painful although some patients experience slight discomfort from the pressure of the material filling the socket.

Sometime during the first appointment the iris is painted that will be used in the final prosthesis.  We at Negah Toos Ocular Prosthetics have developed a painting technique we call close encounter painting.  This means the fine lines in your iris are duplicated in such detail that when someone is close to you, (close encounter) the iris of your prosthesis looks like your natural eye.  Many patients tell us that their family and friends can not tell which eye is the prosthesis and that our work goes unnoticed.  Click here to see an enlarged sample of our painting method.

All of our custom-made ocular prostheses are created with our close encounter painting procedure, so you get the best possible reproduction of your natural eye.
From the impression of the socket, a wax model is made for the fitting of the final shape.

As the fitting proceeds, the model is shaped to form the lid opening to match the normal eye as closely as possible. Next, the iris cornea piece is set into the model and moved as necessary until the position of the iris is centered to match the companion eye.

Once the shape and centering requirements have been met, the model is cast in a stone mold and duplicated in white plastic.  At this time, the iris piece is also cured into the plastic piece in an oven or curing tank.

Following this procedure, some of the plastic has to be removed to allow for the final painting and scleral tinting. All the details, including the small blood vessels, are then painted to match the natural eye.

After the final surface painting process, the eye is covered with a layer of clear plastic to seal in the artwork and give the eye prosthesis a rounded shape. Once finished, it is ready to be inserted into the socket for a final fitting evaluation.


 The total time required to make a prosthesis varies with the requirements of each patient, the type of eye being made and the workload of the office. We offer special appointments for one or two day service which should be discussed at the time of scheduling your appointments.

Following new surgery, follow-up care is usually needed for one year after delivery of the prosthesis. It often takes many months of healing for the socket tissues to settle and for all of the swelling to subside. Because of this, enlargements are often necessary some months after the original fitting.
