CATARACT

Cataract occurs when the eye’s natural clear lens becomes cloudy, reducing the quantity of light entering the eye which results in blurred vision. Cataract is the most prevalent cause of blindness worldwide.

WHAT ARE THE CAUSES?

Cataract occurs as a result of the ageing process. It is common in the elderly and is thought to be caused by UV light exposure. Diabetes, long-term use of certain medications, severe injury, or persistent inflammation can all raise the chance of getting cataracts. It can even happen to children occasionally.

WHAT ARE THE SYMPTOMS?

  • The most typical symptom of cataract is a gradual, progressive blurring of vision that is uncorrectable even with spectacles.
  • Foggy, cloudy, or hazy eyesight with both distant and near vision, making objects look less bright.
  • Driving at night is difficult due to bright headlights.
  • Glare from lamps or the sun.
  • Seeing double.
  • Colour perception is impaired.
  • A consistent change in spectacle power may suggest cataract development.

WHAT ARE THE DIFFERENT TYPES?

There are 4 main types of cataract:

Nuclear cataract

The most common type of cataract, nuclear cataracts are formed when the centre of the lens gradually hardens and becomes cloudy with age.

Cortical cataract

Unlike nuclear cataracts which occur in the centre of the lens, cortical cataracts work their way from the edge towards the centre of the lens.

Posterior subcapsular cataract 

Formed at the back of the lens, posterior subcapsular cataracts are often seen in individuals who are on corticosteroids or diabetes medication.

Congenital cataract

These cataracts occur at birth and can range from mild with no further progression, to major and causing visual impairment.

CATARACT SCREENING TO GET THE BEST POSSIBLE TREATMENT

Cataracts develop gradually. Some individuals with cataract are not aware of it as the deterioration of their eyesight is not noticeable. If you are 45 years of age or older, schedule a cataract screening to detect it early so that you are able to choose the best possible treatment available.
