About Cataracts - Northern Eye Surgery SYDNEY

Cataract is the name given to a cloudy lens of the eye. The presence of a cataract results in less light
entering into the eye. The light that does enter the eye is scattered and poorly focused. This causes
the vision to be blurred.

What causes cataracts?

Most cataracts are a consequence of age. Other factors associated with cataract formation include
diabetes and eye problems such as past eye inflammation or injury. Some medications can
contribute to the development of cataracts.

What is cataract surgery?

Cataract surgery is undertaken to remove the cataract and restore clear vision. During surgery the
clouded lens is removed and replaced with a clear artificial lens. The artificial lens is also known as
the intraocular lens (or IOL).

Cataract surgery is available to patients if cataract formation is causing blurring of vision which impairs
common activities such as driving or reading. The improved vision after cataract surgery should enable
a better quality of life and reduce the chance of accidents or injuries due to failing eyesight.
