You will soon be familiar with inserting or removing the prosthetic eye.

After a while, you will find it very simple and it will become natural to handle the prosthetic eye.

In order to avoid damage, use a soft base (towel) when you insert or remove the prosthetic eye.

Clean the prosthesis before insertion.

It is also recommended to wet the shell before insertion, as it makes it easier to slide into the eye cavity.

Please note: if you rub the artificial eye, always rub towards the nose, otherwise you may turn the shell and it could fall out.

Please note:

If you rub the artificial eye, always rub towards the nose, otherwise you may turn the shell and it could fall out.

Normally, the narrow side of the prosthesis faces towards the nose and the wide side faces outward.



Take the glass eye in one hand holding it in the position of the focal point.

Then, with the other hand lift the eye lid and slide now the prosthetic under the upper eye lid and hold the prosthetic with the hand until a gentle pull on the lower eye lid (with the other hand) lets the prosthetic slid into the eye cavity.

If necessary, correct the position with a slight pressure with a finger.

This would remove any air bubbles that might have been trapped. .



The shell should be removed by looking upwards.

To remove, press the lower eye lid down, until you see the edge of the shell.

Slide the tip of your pointer finger under the lower edge of the prosthetic and together with the middle finger hold the artificial eye and pull it downwards out of the eye cavity.

It is also possible to get a small hook-like instrument from your ocularist for removing the shell.


Treatment of the prosthetic eye and FAQ

How do I keep my prosthetic eye clean?

The artificial eye should be cleaned at least once a day.

Best is to place it in its plastic container with lukewarm water.

To remove persistent contamination, place the glass eye in water which contains one teaspoon of salt per litre for about 10 minutes.

Then clean it with a soft brush.

Afterwards, wash your prosthesis thoroughly with clear water.

Do I have to remove the eye during the night?

The prosthesis may remain in the eye cavity and only be removed for cleaning as long as the patient is comfortable.

If the prosthesis is not worn during the night, it should be cleaned and kept dry in a closed container.

In particular cases it is better to not wear the prosthesis during the night.
The ocularist shall advise you specifically in this regard,

When do I have to get my first prosthesis after the nucleation?

Depending on the opinion of he doctor, the first prosthesis should be fitted between 2 to 4 weeks following the enucleation.
Not only for aesthetic reasons but also based on health concerns, it is recommended to wear a prosthetic eye.
Please also consider the eye cavity may shrink if it was empty for a longer time.

How long does the manufacturing process of a prosthetic eye last? Video

A prosthesis made of special glass is manufacturer in the presence of the patience and can be inserted and worn after only one visit.

If you decide to wear a prosthesis made of resin, you need two appointments with 2 weeks in between.

Causes the adaptation of the artificial eye any pains?

The fitting of an artificial eye is not connected with any pain and also day-to-day handling of the prosthesis can be learned quickly

Will the artificial eye move in the eye socket like the natural eye?

Essentially for the natural mobility of the artificial eye is the existence of the eye muscle and the composition of the eye socket.

If these prerequisites are appropriate, a very good movement of the artificial eye can be achieved.

How often do I have to replace the artificial eye?

Since the glass eyes eventually deteriorate due to different factors such as environmental influences, consistency of the eye cavity or heavy tear fluid production Prosthetic eyes made of special glass have a recommended wearability of one to one and-a-half.

When the surface starts to be rough and irritates the eye cavity causing regular tearing, this may be a sign that it should be replaced.

Acrylic eyes have greater signs of wear and tear than prosthesis from special glass due to their softer surface.

The ocularist however can remove these scratches by polishing the prosthesis, we recommend this once a year.

It is recommended for both materials to only wear the artificial eye for as long as it is comfortable.

This will prevent changes and damage to the eye cavity in most incidents.

Can I do sports with the artificial eye?

In principle, all leisure activities can be carried out as usual with an artificial eye.
The artificial eye is protected well by the eye socket so that it cannot be damaged at during sport activities either.
Swimming is also possible with the artificial eye, but swimming glasses should be worn.
If you want to dive with oxygen bottles it is recommendable to wear an artificial eye of acrylic because of the possibly arising pressure.

What is an implant?

An implant compensates the loss of volumes in the eye socket and achieves a better mobility of the artificial eye.
