Cataract Awareness – What are cataracts?

A cataract is a common eye disease that often develops slowly and affects the vision of one or both eyes. June is Cataract Awareness Month, but awareness of this disease should continue all year round! Continue reading to understand what cataracts are and how to prevent them, as well as the possible treatments which exist.


What is a cataract?

A cataract is a clouding of the eye lens causing blurred vision, and other visual symptoms such as:

  • Multiple images
  • Faded colours
  • Shadowing
  • Glare
  • Difficulty driving at night

Who can get cataracts?

Children can be born with cataracts and adults can have a hereditary tendency to develop cataract. Most cataracts are due to age-related changes in the lens, which makes them more common among older adults. Cataracts can be diagnosed by a thorough eye examination, carried out by an Ophthalmologist specialising in cataract surgery.


What factors increase my risk of getting cataracts?

Factors that increase your risk of cataracts include:

  • Getting older
  • Diabetes and obesity
  • Drinking excessive amounts of alcohol
  • Excessive exposure to UV in sunlight
  • Dehydration
  • Exposure to ionising radiation, e.g. X-rays and cancer radiation therapy
  • Family history of cataracts
  • High blood pressure
  • Smoking
  • Previous eye surgery, injury or inflammation
  • Prolonged use of oral corticosteroid medications


What can I do to avoid getting cataracts?

There are several steps you can take to avoid the development of a cataract:

  • Good diet which is low in sugar, high in grains, leafy green vegetables and with anti-oxidant qualities.
  • Maintain correct weight for height and age
  • Avoid excessive alcohol
  • Avoid dehydration by drinking lots of water
  • Don´t smoke
  • Wear good sunglasses and a hat with brim to protect against UV light rays


Is cataract surgery safe?

Cataract removal is one of the safest and most common eye operations performed in the UK. Most people who have cataract surgery have much better vision afterwards.


When will I need cataract surgery?

You will need the surgery when the cataract begins to interfere with your vision. Sometimes if the cataract is early, it only affects the vision a little or not at all and no treatment is needed. When a cataract progresses to the point that it affects your ability to do normal everyday tasks such as:

  • Reading
  • Driving
  • Seeing colours well
  • Distressing symptoms such as glare and giving you reduced vision in reduced light conditions

In these cases, surgery is most likely needed.


Can I have both cataracts operated on at the same time?

It is best to space the surgery about one or two weeks apart. Although surgery is very safe, the minute risk of infection inside the eye dictates that surgery is staggered. Also after cataract surgery, the eye should be covered with an eye pad overnight. It is difficult for two eyes to be covered if they are operated at the same time!


Will I be asleep for my surgery?

No, a general anaesthetic is rarely necessary. The surgeon uses local anaesthetic and you will not feel anything.


Will I have to wear glasses afterwards?

Usually, you will still have to wear reading glasses. However, if you opt to have Premium Intraocular lens implanted, that allows you a strong degree of distance and near vision. Ask your surgeon about Premium lenses.


What is an Intraocular lens?

An Intraocular lens is a very highly specialised tiny lens, which is implanted into your eye into the pocket where your natural cataract lens was. It allows you to see clearly after surgery. The nurses at Clinica London measure your eye before cataract surgery to determine the strength of the Intraocular lens you will need.


How soon will I be able to see after my surgery?

Your eye will be covered with a gentle eye pad for the first 24 hours. Once the eye pad is removed by the nurse at Clinica London on Day 1 post surgery, you will already have very good vision, as long as the back of the eye or retina, is healthy.

How can I improve my vision without surgery?

Often, the symptoms of early cataracts can be improved by simple measures for a period of time before you need cataract surgery. Take these steps to improve your vision:

  • See optician for new glasses
  • Use a brighter reading light
  • Have anti-glare sunglasses
  • Avoid driving at night or in bright sunlight
  • Get your diabetes under control
