Cataract

What is cataract?

A cataract is a condition where the Natural Crystalline Transparent Lens becomes cloudy or hazy.  An estimated 75 million Indians over the age of 50 have cataracts and it is the most frequent cause of preventable blindness in the world.

Why are they caused?

There are various causes for cataract formation. Some of the more common ones are:

  • Increasing Age
  • Exposure to Ultra Violet Radiation
  • Smoking
  • Alcohol consumption
  • Diabetes,
  • Hypertension
  • Injury
  • By birth (congenital cataract)
  • Metabolic disorders (galactosemia, mucopolysaccharidoses)

With ageing as well as the aforementioned conditions, the ocular capacity to withstand insult due to oxidative stress is reduced. The natural proteins of the eye are not able to withstand the tissue injury due to various causes (oxidative stress) – hence they degenerate and become cloudy or opaque.

While a comprehensive eye examination by an eye care practitioner can determine for certain if you have a cataract forming, there are a number of signs and symptoms that you can look out for:

What are the symptoms of cataract?
  • Blurred or foggy vision where colours may seem yellowed/washed out
  • Frequent change of spectacle numbers
  • An increased sensitivity to glare, especially at night
  • Curtain like feeling over eyes—as if seeing through a filter paper

A complete eye examination will definitely diagnose the presence of cataract by your eye specialist.

What is the treatment for cataract?
The only definitive treatment is surgical removal. Changing the glasses is not only temporary, but mostly ineffective.
When should you get operated?
You and the eye surgeon will decide together when the cataract is to be surgically removed. Normally, whenever the cataract interferes or is likely to interfere with routine day-to-day activities, it is time to remove it.
What will happen if I am not treated?
If you don’t get treated the cataract becomes harder with age and more difficult for the operating surgeon to remove and also leads to longer post-operative recovery time. In serious cases it can mature or ripen which will result in an increased chance of getting glaucoma – increased eye pressure – which is an ocular emergency.
