CATARACT

What is cataract surgery?

Cataracts form when the eye’s natural lens becomes cloudy as a result of eye tissues breaking down and proteins clumping together. They impair vision and can only be rectified with cataracts treatment. The surgery involves removing your eye's natural, clouded lens and replacing it with an artificial one.

Cataracts tend not to have any symptoms in their early stages, but you will notice them when they grow large enough to prevent light from passing through the lens. Symptoms at this stage include cloudy or double vision, faded colours and haloes when looking at bright lights. Cataracts get worse with time and usually affect people in their 70s, but they can occur at any age.

During cataract surgery, we remove the eye’s natural, clouded lens and replace it with an artificial one – either a monofocal or multifocal lens, depending on your visual requirements.

If you need to wear glasses, a new lens with the correct focusing power is implanted so that glasses are no longer required. This includes improvement in both reading and distance vision when a multifocal lens is used.
