Cataracts are one of the most common causes of visual impairment in old age and affect millions of people worldwide. Although the diagnosis often sounds frightening at first, the good news is that cataracts are now a very treatable eye disease. With modern surgical procedures, patients can often completely restore their vision and thus significantly improve their quality of life.
In this article, you will learn everything you need to know about cataracts - from the causes and symptoms to the latest treatment options. Find out how early diagnosis and timely treatment can help you to preserve your vision and stay active. If you or someone close to you notice the first signs of visual impairment, this article can serve as a valuable guide.
Prof Dr Matthias Becker, what is a cataract?
A cataract is a clouding of the lens of the eye that causes vision to become increasingly blurred and out of focus. Normally, the lens in the eye is transparent and helps to focus light onto the retina, which is essential for clear vision. With a cataract, the lens becomes cloudy, which impairs vision.
What are the causes of cataracts?
The most common cause of cataracts is age. With increasing age, the structure of the lens changes and a natural clouding occurs. However, other factors can also play a role:
- Genetic predisposition
- Diabetes mellitus
- Long-term use of medication, especially corticosteroids
- Injuries to the eye
- Certain eye diseases or inflammations
How do you recognise a cataract?
The symptoms of cataracts usually develop gradually and are often not immediately noticeable at the beginning. The most common signs include
- Deterioration of vision, especially in dim light or at night
- Increased sensitivity to glare, e.g. when driving at night
- Blurred vision, which is often mistaken for a spectacle fitting
- Change in colour perception (colours appear paler)
If these symptoms occur, it is advisable to consult an ophthalmologist.
Can cataracts be treated?
Yes, cataracts are treatable in most cases. In the early stages, it can be corrected with new glasses or a visual aid, but in advanced cases only surgery can help. This involves removing the cloudy lens and replacing it with an artificial one (intraocular lens). Nowadays, this operation is very safe and is usually performed on an outpatient basis.
How does the operation work and how long does the recovery take?
Cataract surgery is a routine procedure that is performed under local anaesthetic. The cloudy lens is removed through a small incision and replaced with an artificial lens. The entire operation only takes about 15 to 30 minutes. The recovery time is usually short. Most patients can return to normal life the very next day, although special aftercare is required for the first few days.
Are there any risks associated with cataract surgery?
As with any operation, there are risks associated with cataract surgery, even if these are very low. The most common complications include
- Infections
- Post-cataract (a clouding of the posterior capsule of the lens, which sometimes needs to be treated)
- increased eye pressure or retinal problems.
However, these risks are rare due to modern techniques and the high success rate of the operation.
What are the latest developments in the treatment of cataracts?
Cataract surgery has improved considerably in recent years. The use of high-quality intraocular lenses, which can improve not only visual acuity but also visual quality (such as contrast vision and colour perception), is a major advance. There are also so-called "multifocal lenses" that enable near and far vision, making the wearing of glasses after surgery unnecessary in many cases. The choice of the right lens must be adapted to the individual situation, which we will be happy to do together with you in a detailed consultation.
How can cataracts be prevented?
There is no way to prevent cataracts, especially if they are age-related. But healthy lifestyle habits can reduce the risk:
- Protecting your eyes from UV radiation (e.g. with sunglasses)
- Avoiding smoking
- Eating a balanced diet rich in antioxidants (e.g. vitamins C and E)
- Regular eye examinations for early detection
Are there any frequently asked questions from patients regarding their eyesight?
Yes, many patients wonder whether they will be able to see normally again immediately after cataract surgery. The answer is that most patients experience a significant improvement in vision, but the adjustment to the new lens can take a few days to weeks. Another common question concerns the need for glasses after surgery: some people still need glasses, especially for near vision, depending on the type of lens that has been inserted. We are happy to clarify all of these questions with you in a consultation, as there are various factors that need to be taken into account.
What are the next steps if a cataract is suspected?
If someone suspects that they have a cataract, they should consult an ophthalmologist. The doctor will carry out a thorough examination that includes the vision and the lens of the eye. A personalised treatment plan can then be drawn up.
