Cataract

What is a Cataract?

A cataract is the term used to describe clouding of the naturally clear crystalline lens inside the eye.  

Throughout your life the lens is clear and flexible to enable you to have clear natural vision. A cataract develops when this lens starts to discolour and harden as its protein structure deteriorates. 

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

What are the symptoms?

Early stage cataracts may only minimally affect your vision, and many people are not aware they have the condition.  

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.
