What is a cataract?
There is a small lens in the middle of the eye called the crystalline lens. A cataract is when this lens is cloudy instead of clear. Some people describe it as a film growing over the eyes, but this description is inaccurate. In most people, this lens is clear at a young age and gets cloudy with age. However, babies and young people can also have cataracts as a result of different causes.

How do cataracts affect vision?
Cataracts make the vision misty or foggy which is noticeable, and also affects the brightness of colours which might not be so obvious. The common age-related cataract usually takes a number of years to progress and become problematic.

What is the treatment for cataracts?
A short surgical procedure can be performed to remove cataracts if they start affecting your lifestyle. An artificial lens is usually implanted to replace the original crystalline lens. The surgery has very high success rate and few complications.

Can cataracts come back?
No, cataracts cannot come back. However, it is not uncommon for the vision to start becoming cloudy again after a few years or even months. This is not the cataract returning, but is cloudiness of the capsule or sac which holds the new lens implant. This can be easily treated with minor laser treatment lasting a matter of minutes.
