How are cataracts treated?


We make it a priority to ensure you are at ease during your cataract surgery. 

Cataract surgery consists of removing the natural lens in the eye and replacing it with an artificial intraocular lens (IOL). The IOL is a clear plastic lens approximately six millimetres in diameter. It replaces the natural lens and remains permanently within the eye. The lens has small spring-like arms called haptics, which prevent the lens from moving out of place.

When cataract surgery is performed, most of the natural lens is removed but most of the capsule or membrane that surrounds the lens is left in place. This capsule helps to keep the fluids behind the lens undisturbed and also holds the intraocular lens (IOL). A numbing gel is placed in the eye and light intravenous sedation is administered. You should not see instruments coming toward your eye and you should not feel pain in your eye during surgery. Phacoemulsification (a type of ultrasound) is the most common method used to remove the cataract.

What is a cataract?

A cataract is a clouding of the lens in the eye which leads to a decrease in vision. Cataracts often develop slowly and can affect one or both eyes. Cataracts can be a result of normal aging, an eye injury, previous eye surgery, or if you have taken certain medications. To date, there are no known methods of preventing cataracts


How do you know you have cataracts?

If you start experiencing symptoms such as cloudy or blurry vision, faded colours, trouble seeing at night, frequent changes in prescription glasses, you need to have your eyes examined by an eye care professional.

Cataracts can only be detected by having a comprehensive eye examination.
