Eye Conditions

Cataract

What is a Cataract?

A cataract is the clouding of the lens inside your eye and they are very common as we get older. 

There is a clear and flexible lens that sits inside your eye (behind your pupil and iris), and as we age this lens can become cloudy. This is called a cataract.

A cataract is not a film or growth over the eye, this is a common misconception.

Without treatment, cataracts will continue to become cloudier and you may eventually go blind. While both eyes may have cataracts, it is usual for one to be more progressed than the other.

Cataract surgery is a safe and effective operation to restore clear vision by replacing the cloudy lens inside your eye with an artificial lens, called an intraocular lens (IOL).

What are the symptoms?

In the early stages of a cataract forming, your vision may only be minimally affected. You may not be aware that you have the condition until you have an eye test.

Over time, you may become aware of the following:

  • Cloudy, foggy or frosty vision
  • Double vision in one eye
  • Increased sensitivity to bright light and glare 
  • Difficulty driving, especially at night 
  • Trouble reading and recognising faces 
  • Colours appear dull and faded 
  • Updating your glasses no longer provides you with clearer vision

What causes a Cataract?

Cataracts are a normal part of the ageing process and are one of the most common eye conditions.

Generally appearing in people who are over the age of 60, other factors that can cause a cataract or accelerate its growth include: 

  • Smoking 
  • Excessive exposure to UV and other types of radiation
  • Use of certain medications (e.g., Corticosteroids) 
  • Previous blunt/penetrating ocular trauma, surgery or disease 
  • Systemic disease (e.g., Diabetes and other metabolic disorders) 
  • Genetics and congenital disorders

Cataract Surgery

Cataract surgery is the only effective treatment available and the most common surgery is microincision phacoemulsification cataract extraction, which involves removing the cloudy crystalline lens and replacing it with an artificial intraocular lens (IOL).

At your consultation, your surgeon will discuss the different lens designs available, and, considering your lifestyle, the unique features of your eyes and your visual requirements, which IOL is recommended for you.
