Frequently asked questions about Cataract

I have been diagnosed with cataracts at 20, is this normal ?

Most cataracts are related to aging, but some cataracts are present at birth (congenital cataracts). Other types of cataracts are caused by shocks to the eye (traumatic cataracts) or by taking medication; cortin, for example. Some diseases such as diabetes can accelerate the onset of cataracts.

I have a cataract in my right eye, what will happen to my left eye ?

A cataract is not a contagious disease; it does not spread from one eye to the other. Most often though, it occurs in both eyes at once.

Can I become blind over time ?

The final stage of cataracts is blindness, but cataracts can be easily treated with simple surgery.
It should be noted, however, that cataracts are the leading cause of blindness in developing countries as cataract surgery is not often practiced there.

I’ve been prescribed a treatment, is it effective ?

Eye drops or dietary supplements have no demonstrated efficacy in treating cataracts in a preventative or curative manner.

Cataracts were discovered during a routine control, do I need to have emergency treatment ?

There is no urgency to operate on the cataract if you do not have visual discomfort.

At which age is possible to have cataract surgery?

There is no recommended age for surgery. You should think about the operation as soon as you are significantly hindered in your daily activities. You should not wait until the crystalline lens is too hard and too opaque. Although the average age for cataract surgery is between 60 and 70 years old in France, some people experience discomfort much earlier. Moreover, the indication will also depend on the type of cataract you suffer from. An active cataract patient will be operated on quickly.

When to have cataract surgery?

As soon as you feel visual discomfort and your eyesight deteriorates despite the appropriate correction.

I've been diagnosed with cataract, do I need to have an emergency operation?

Apart from very rare exceptions, there is no urgency to operate. Once again, it is your feelings that will lead you to consult for an operation.

Why have cataract surgery?

There is no obligation to have surgery. Some elderly people whose daily life does not require very good eyesight cope very well with this condition. On the other hand, if the cataract prevents you from leading a normal life (driving, reading...) or restricts you in your leisure activities (reading, sewing...), you should not hesitate to consult.

What are the side effects of cataract?

The side effects of a cataract operation are mainly related to the eye drops that you will have to put in your eyes after the surgery: allergies or irritations. Luckily, not all patients will suffer from this kind of inconvenience, but sometimes some people may have dry eyes prior to the operation. This condition, commonly known as "dry eye", is due to a dystrophy of the Meibomus glands, small glands located along the eyelids that ensure the quality of the tear film. This can result in a feeling of eye irritation, glare or fluctuating vision. These symptoms regress if this dry eye is treated before/during and after cataract treatment. If a patient were to have dry eyes, they would be diagnosed anyway during the comprehensive check-up that is routinely carried out at the Donate Vision Clinic. However, eye drops are still essential after each operation as they reduce the risk of inflammation and post-operative infection.

What are the consequences of cataract surgery?

They are very simple and brief. It is necessary to take a little rest and above all, stay in a clean environment the days following the operation. The aim is to avoid any infection and any "brutal" contact with the recently operated eye.

How to avoid cataract?

Cataract itself cannot be avoided since it is a natural phenomenon linked to the ageing of the eye. The only "avoidable" cataract is that caused by direct trauma to the eye (traumatic cataract). On the other hand, as in many general pathologies, a healthy lifestyle can help you to preserve your eyes for longer:

  • Protect your eyes from UV rays with sunglasses.
  • Avoid tobacco and alcohol
  • Controlling blood sugar levels in diabetes
  • Have your doctor check the long-term use of certain medications (corticosteroids, etc.).


Can cataracts be cured naturally?

Unfortunately, there is no non-surgical treatment for this condition. But as seen previously, a varied quality diet and a healthy lifestyle remain good natural methods against the ageing of the eye and ageing in general.

Is it possible to drive after a cataract operation?

You will not be able to drive immediately after your operation and someone will have to accompany you. However, you will see the surgeon the day after the operation and only he can give you the green light to drive. It is usually possible two to three days later.

When can you resume sport after cataract surgery?

You can resume sports 15 days after the operation. But time is the best ally for your healing, so be careful with contact sports in the following weeks.
