About Cataracts

 

Cataracts are one of the most common eye diseases in Hong Kong. It is also the number-one cause of blindness. In 2009, there were roughly 54,000 patients waiting for cataract operations at hospitals under the Hospital Authority. Furthermore, of those patients, up to 42,000 of them were aged 71 and above.

As an individual becomes older, the lens of the eye starts to age and gradually turns cloudy. The lens is responsible for focusing light onto the retina, much like the way the lens inside a camera works. If the lens becomes cloudy, light cannot be focused and patients suffer from impaired vision.
