A cataract is the clouding of the normally clear lens of your eye causing blurred vision. Cataracts make it more difficult for you to see (especially at night), watch TV or drive.  Most cataracts develop slowly as you get older and will affect your eyesight when the clouding spreads to the centre of your lens.

Cataract surgery is recommended when your vision is affected to a point that it interferes with your lifestyle, work or ability to drive.  Phacoemulsification uses ultrasound energy to dissolve and remove the cataract without the need for stitches.  An Intra-Ocular Lens (IOL) will be implanted into the eye so that your vision can be restored.
