Cataract

Cataract is a condition in which the natural lens of the eye becomes cloudy overtime, causing blurred vision. Cataracts usually develop as a result of ageing. The natural lens of the eye is made up of protein and water, over time these proteins are altered ultimately causing gradual clouding of the lens.

What are the symptoms of cataract?

Usually cataracts will cause symptoms, including:

  • Blurred Vision
  • Double Images or Ghost Images
  • Glare or Sensitivity to Lights
  • Haloes Around Lights or Night-Driving Difficulties
  • Recent Changes in Glasses Prescriptions (Myopic Shift)

What causes cataract?

Most commonly, cataract is caused by age. They are very common, most people older than 70 will have some early cataract.

Other causes of cataracts include:

  • Medications (such as Steroids)
  • Other Eye Diseases (such as Uveitis or Retinitis Pigmentosa)
  • Congenital or Hereditary
  • Diabetes
  • Eye Trauma

What is the treatment of cataract?

The only treatment for cataract is to remove it with an operation. After the cataract is removed, a new lens is inserted into the eye. This new lens is needed to allow light to focus again on the retina at the back of the eye.

The operation usually takes about 10 minutes, but it can be longer if you have a larger cataract.
