CATARACT
The term cataract comes from the
Middle Ages, from the Greek word Katarraktes, meaning waterfall.
Cataract is a darkening of the crystalline, that is, the lens
inside the eye, which is normally transparent. Cataracts develop
over the years and do not get worse with reading or forcing one's
sight.
What are the signs of a
cataract?
Blurred vision, photophobia or increased sensitivity to light
(especially at night), if you need to change glasses often, if
colours lose their intensity and saturation.
Why has this happened to
me?
Except a few cases of congenital or metabolic
diseases etc., the most common cause is senil cataract, that is
to say, it normally appears from about 55 years of age.
What is the treatment for
a cataract?
Currently, treatment is with laser-ultrasound.
Cataracts should be treated as soon as possible, before they interfere
strongly with one's work or daily life.
What does the operation
consist of?
The operation is called PHACOEMULSIFICATION
and is currently performed with a short incision of 1.5-2.0 mm.
It does not need stitches. An artificial lens is implanted in
place of the opaque lens. This artificial phace does not need
stitching inside the eye. It is suspended inside the capsular
sac, which is stabilised automatically by means of a small elastic
arm.
The operation takes about 10 minutes.
Do I need to stay in hospital?
No. The operation is performed in out-patients.
You only need to stay at our clinic for about two or three hours.
We use a local anaesthetic, of eye drops, which is administered
a few minutes before the operation. A small quantity of anaesthetic
is usually injected into the eyelid so that the patient feels
more comfortable during the operation.
Can this operation be done
in severe cases of short-sightedness or long-sightedness?
Yes. There is also the added advantage
that, due to the special calculation of the graduation of the
lens, you will not need to use such powerful glasses. The implanted
lens can be graduated so that you will not need to wear glasses
at all, or in the case of having to wear them, you will only need
glasses with minimum graduation and only for certain tasks close-up.
In many cases you will not need to wear glasses for long distances. |
