Eye condition
Cataract
A cataract is a clouding of the natural lens of the eye – usually age-related. Vision gradually becomes duller, as if seen through a veil.
Schematic illustration for explanation – medical approval required.
Important pre-operative examinations
Before the operation we check the intraocular pressure, assess the retina and macula and measure the eye. A clear lens alone is not enough: the retina, macula and optic nerve also determine how well you will see afterwards. A macular OCT can reveal hidden changes early.
Treatment
The only effective treatment is surgery: the clouded lens is removed and replaced by an artificial lens – gently, as an outpatient and usually within a few minutes per eye. The right lens depends on the findings, your everyday life and your visual habits.
After the operation
Visual acuity may still change over the first few days. Use the drops as prescribed, do not rub the eye and attend your check-up appointments. In case of severe pain or a sudden deterioration of vision, please contact us immediately.
Typical symptoms
- Blurred or dull vision, colours appear paler
- Increasing sensitivity to glare, e.g. when driving at night
- Frequently changing spectacle prescriptions
The clouding usually develops slowly over years – many people do not notice it at first at all.
How we examine
We make the diagnosis at the slit lamp; in addition we check visual acuity and the retina in order to rule out other causes.
How we treat
The only effective treatment is surgery with the implantation of an artificial lens – as an outpatient in our Stadtmitte surgery centre.

A sudden, marked deterioration of vision is not part of a cataract – please have it assessed promptly.
