Cataracts

Learn more about cataracts and how they are treated.

Overview

A cataract occurs when protein builds up in the lens of your eye, causing it to become cloudy rather than clear.

For more information on cataracts, visit the Canadian Ophthalmological Society.

When there is enough buildup, your vision gets blurry. Cataracts are common, and most people get cataracts as they age.

Symptoms

Symptoms

Early signs of cataracts are hard to notice. As protein builds up in your eye, you may:

  • Have difficulty seeing small details
  • Notice colours appear less bright 
  • See halos around bright objects at night
Diagnosis

Diagnosis

An optometrist or ophthalmologist can detect a cataract during a regular eye exam, when your pupils are dilated. They can also check your eyesight to see how it has changed over time.

Treatment

Treatment

If you are diagnosed with cataracts, you may need prescription lenses to help improve your vision.

As your cataract worsens, your ophthalmologist may recommend surgery to improve your vision. 

Before surgery, you will have an appointment to measure the size and shape of your eye. During surgery, an ophthalmologist will remove the damaged lens of your eye using either a scalpel or laser. Next, the surgeon will insert a new lens, called an intraocular lens.
