How is Erickson's Eyes in Spokane different from other ocularists?

We innovate! Part of our long family tradition is competitiveness mixed with curiosity. Most ocularists are using techniques we abandoned in the 1950's. We strive for detail in appearance as well as pursuing the perfect fit to allow the most motion and lid function. Many of our techniques are unique to our office.

How long does it take to have a prosthesis made?

Two to three days for most prostheses, but the more complicated the case, the more difficult it is to predict the time needed.

Does insurance cover the cost?

Every insurance company is different. Our office manager can help you on an individual basis. Learn more about insurance and financing an eye implant here.

How much does a prosthesis move?

Most move some, but not perfectly. Each patient has a unique socket and a different outcome. The initial injury, type of implant, scar tissue present in the socket and health of tendons and muscles in the socket and eyelids all play a part in the movement and overall outcome.

Do you use a photograph of the iris, or paint it?

We paint all of our prostheses. Photography, even digital photography, does not have very accurate color reproduction and a skilled painter can achieve a level of detail similar to a digital photograph.

What painting medium do you use?

We use pure pigments mixed with raw plastic, the same plastic the prosthesis is made out of, so it won’t delaminate.

How long does a prosthetic eye last?

On average, an artificial eye will last five to six years.

Why do you have to replace a prosthesis?

Eye sockets change shape over time making the prosthesis fit poorly. The plastic the prosthesis is made out of also absorbs body fluids and can being degraded by exposure to light.

Why should I replace my prosthesis if it feels fine?

People get used to many things, especially if they change slowly. Many sockets show signs of long term irritation even though the patient does not feel any pain. Some people have even reported bleeding without any irritation.

How do you care for a prosthesis?

A prosthesis should generally be removed monthly for cleaning at home. A professional polish from your ocularist should be arranged twice- yearly. Replace the prosthesis as needed.
