Cataract Detection & Co-Management in North York
Cataracts cloud the eye's natural lens and develop so gradually that many people don't notice until vision is affected. With early detection and careful monitoring, cataracts can be managed for years — and we coordinate surgical referral when the time is right.
Symptoms of Cataracts
Cataracts develop slowly and may affect one or both eyes. You may not notice them until they begin to affect your vision. Common symptoms include:
- Blurred or cloudy vision.
- Difficulty seeing at night.
- Sensitivity to light and glare.
- Seeing “halos” around lights.
- Frequent changes in your glasses or contact lens prescription.
- Fading or yellowing of colours.
- Double vision in a single eye.
If you notice any of these symptoms, don't wait to book an eye exam — the sooner cataracts are identified, the better we can support your vision.
Who Is Most at Risk?
Cataracts can affect anyone, but several factors increase the risk of developing them:
- Age — most cataracts develop after 40, with risk rising significantly over time.
- A family history of cataracts.
- Medical conditions such as diabetes, hypertension, and obesity.
- Previous eye injury or eye surgery.
- Prolonged use of corticosteroid medication.
- Excessive sun exposure — a reason to always wear UV-protective sunglasses.
- Smoking and heavy alcohol consumption.
The Different Types of Cataracts
Cataracts are categorized by where they form in the lens and what causes them. The most common types include:
Nuclear cataracts
form in the centre of the lens and are associated with aging; the lens gradually yellows or browns, reducing vision quality and colour distinction.
Cortical cataracts
start at the edge of the lens and extend inward in a spoke-like pattern, often causing glare and problems with contrast.
Posterior subcapsular cataracts
develop at the back of the lens, often progress faster, and can interfere with reading and cause glare or halos at night.
Congenital cataracts
present at birth or developing in childhood, due to genetic factors, infections, or other conditions; early detection is crucial.
Secondary cataracts
result from other conditions such as diabetes, certain medications, or previous eye surgery.
Noticing Cloudy or Dimming Vision?
A comprehensive exam can determine whether cataracts are the cause and how best to support your sight.
