A cataract is an opacity (or cloudiness) in the lens of the eye. This cloudiness develops inside the lens and restricts light passing through the eye and reaching the retina. When this occurs, vision is affected. An opacity can be quite minor or it can become so marked that it prevents adequate vision.


The most common cause of cataracts is ageing. Others include:

  • Inherited or developmental problems
  • Health problems such as diabetes
  • Medications such as steroids
  • Trauma to the eye


Common symptoms of cataracts are:

  • Cloudy or blurry vision
  • Light sensitivity from car headlights that seem too bright at night; glare from lamps or very bright sunlight; or the appearance of a halo around lights
  • Poor or reduced night vision
  • Double or multiple vision (this symptom often goes away as the cataract progresses)
  • “Second sight” where near vision becomes possible without glasses again because of the cataract developing in the lens. This state is usually temporary, and followed by progressive loss of distance vision
  • A need for frequent changes of glasses or contact lenses

Cataract treatment

Only cataracts causing symptoms need treatment. Modern cataract or lens replacement surgery is effective in restoring vision to most patients. This involves removing the cloudy lens from inside the eye through a small incision, and replacing it with a new artificial lens, also called the Intraocular Lens (IOL) made from an acrylic material.

Through a comprehensive series of personalised measurements we are able to recommend the perfect IOL to match your individual readings, so we can provide you with the best visual outcome possible.
