Hints concerning the handling of artificial eyes made of glass


Dear patient,
Thanks to their natural imitation, artificial glass eyes make an inconspicuous wearing possible.
They enable a fitting without any problems and thus a self-assured manner. But do never forget
that the precondition for wearing you eye prothesis without any difficulties is the appropriate
care and treatment. They are very simple to carry out if you follow the hints below. For doing
so, read these information carefully. If you have got any questions please contact your ocularist.

Properties of your eye prothesis
Your eye prothesis is a single-piece work. It was specially made and adapted to your eye
socket. The material used is cryolite glass. This high-quality special glass has been know in
Germany since around 1870. It is manufactured in the glassworks in Lauscha. Now as before
cryolite glass has turnedout to be very advantageous in the field of eye prothesis. Because of
the very resistant surface of the artificial eye with regard to the enormously corroding lachrymal
fluid these properties guarantee an optimum compatibility with the mucous membrane.
Artificial glass eyes are manufactured as hollow (double) objects or as very thin bowl protheses.
According to the condition of your eye socket the respective kind of prothesis shall be
determined by your ocularist. The excellent wearing properties of your prothesis make an
optimum flexibility at work, in your free time or when practising sports possible.

Treatment of the eye prothesis
The eye prothesis should be cleaned thoroughly once a day at least. Please use only clean,
lukewarm water. Do not use any hot water as extreme variations in temperature affect the lifetime
of the material. It is also not allowed to use corroding liquids or to clean the surface with hard
objects. If the artificial eye is extremely dirty it can be watered for about 10 minutes. For doing
so, use a sodium chloride solution ( 1 teaspoon of sodium chloride with one litre of boiled- and
cooled down- or distilled water).
Even germicidal liquids can be used for cleaning. Please ask your ocularists. Do not forget to
rinse off the prothesis thoroughly afterwards and to dry it with cellulose. If the artificial eye is
not worn, keep it in a closed, dry box.

Please note. The artificial eye must not be kept in water!

The question if the artificial eye should be worn day and night should be discussed with ocularist
by all means and decided from case to case.

Inserting the eye prothesis
Please note: When inserting or taking out your prthesis this should be done over a soft pad,
e.g. a towel, for avoiding damages to your prothesis. The utmost caution is advised over the
wash-basin, over tiles or similar objects.
Befor inserting the prothesis it shall be cleaned thoroughly. Moisten the artificial eye a bit
to make the insertion easier.
Please note: With normal protheses the short part shows towards the nose. But
this does not have to be the rule as many protheses deviate from this model.
The insertion is carried out by pushing the prothesis under the lifted upper eyelid which is hold
in this position. When pulling the lower eyelid slightly downwards the artificial eye slides into
its final position behind the lower eyelid. If it is necessary, correct the fitting of the prothesis by
touching the eye slightly with a finger so that eventually entered air can escape.
Your ocularist will give you information about exceptions when inserting the prothesis.
.
Taking out the prothesis
Please think of a soft pad when taking out the prothesis so that it cannot be damaged if it falls
down. The artificial eye is taken out with the line of sight upwards. Press the lower eyelid
downwards until the upper edge of the prothesis is free. Then push the tip if your index finger
under the lower edge of the prothesis and place your middle finger on to the artificial eye to take
it out of the eye socket downwards.
If necessary the artificial eye can also be taken out with thumb and index finger. Sometimes a
special instrument (a hooklet or a suction unit) can be required. Your ocularist will give you
advice about it.

Please note: If you rub or wipe on the eye, please do it in the direction of
your nose. If you wipe in the opposite direction (especially on the lower lid),
you could twist the eye or press it out.
