Cataract

A Cataract usually occurs when the lens of the eye becomes cloudy, thus, causing the vision to be blurred. When this occurs, certain activities such as reading, driving a car or even perceiving people from a distance will be difficult.
 

What are the symptoms of Cataracts?
Cataracts usually form over a period. Therefore, their symptoms will manifest over a considerable tenure. They include:

  • Cloudy, blurry, foggy or filmy vision
  • Progressive nearsightedness, especially in older individuals
  • Perception of particular colours
  • Sensitivity to bright light, especially in the night
  • Sensitivity to glares during the day
  • Double vision
  • Changes in current glass prescription

What are the causes of Cataracts?
At times there is a protein build-up in the lens, making it cloudy.This restricts the light from passing clearly through the lens, thus contributing to the loss of vision. At the same time, new lens cells form outside the lens, even as the older cells consolidate at the centre of the lens. This adds to the cataract.

What are the types of Cataracts?

Cataracts are divided into the following different categories:

  • Subcapsular Cataract: This usually occurs at the back of the lens. Individuals who have diabetes or those who are on a high dose of steroid medications have a high risk for this type of cataract.
  • Nuclear Cataract: This cataract forms deep in the central zone of the lens, also known as the nucleus. Nuclear cataracts often occur in older individuals through ageing.
  • Cortical Cataract: This cataract is characterised by its wedge-like opacities that first begin in the periphery of the lens and progress to the centre, forming a spoke-like structure. This generally occurs in the lens cortex, which is a part of the lens that surrounds the central nucleus.

How are Cataracts treated?

Depending on the type of cataract you are diagnosed with, you will be provided with the appropriate treatment. In mild cases, your vision will be corrected with prescription glasses or contacts. However, in extreme cases, a cataract surgery will be recommended. In this process, the affected lens will be replaced with a clear artificial lens, known as anintraocular lens. This lens will remain within your eye for the rest of your life. If other eye problems prevent the use of an artificial lens, the cataract will be removed, and the vision will be corrected with eyeglasses or contact lenses.
