CATARACT

What Is Cataract?

A cataract is a cloudy area in the lens of the eye that leads to a decrease in vision. Cataracts often develop slowly and can affect one or both eyes. The underlying mechanism involves accumulation of clumps of protein or yellow-brown pigment in the lens that reduces the amount of light that reaches the retina at the back of the eye. They are most commonly age related, but can be present at birth.

Cataract Treatment

 

Often cataract does not require treatment. When treatment is required it is done by an ophthalmic surgeon – almost always as an out-patient procedure. Our optometrist Graham is fully accredited to perform a pre-surgery assessment of your eyes and refer you accordingly. After the operation he is also fully accredited to resume your care and perform a post surgery assessment meaning that you are spared another trip to the eye clinic.
