Will diabetes cause cataracts?
If you have diabetes, you may think about how it can affect your eyes. You may have heard that it can lead to eye problems. One common question is, “Will diabetes cause cataracts?”
At My Eye Clinic in Gosforth, England, we hear this question often. The short answer is yes. Diabetes can increase your risk of getting cataracts. It can also make them appear earlier in life.
What is diabetes?
Diabetes is a condition that affects how your body controls sugar in your blood. This sugar is called glucose.
If your blood sugar is too high for a long time, it can affect different parts of your body. This includes your eyes.
There are different types of diabetes, but all can affect eye health if not well controlled.
What is a cataract?
A cataract is when the clear lens inside your eye becomes cloudy. This lens helps focus light so you can see clearly.
When it becomes cloudy, your vision can become blurry. Colours may look dull. Bright lights may cause glare.
Cataracts are common as people get older, but diabetes can make them happen sooner.
How does diabetes cause cataracts?
High sugar levels affect the lens
When blood sugar levels are high, extra sugar can build up in the lens of the eye. This can change how the lens works.
Over time, this can lead to clouding of the lens, which forms a cataract.
Changes in the eye over time
Diabetes can also cause changes in the structure of the eye. These changes can speed up how quickly cataracts develop.
This means people with diabetes may notice vision problems earlier than others.
Do people with diabetes get cataracts earlier?
Yes, many people with diabetes develop cataracts at a younger age.
Cataracts are usually linked to ageing, but diabetes can bring this forward.
This is why regular eye checks are very important if you have diabetes.
What symptoms should you look for?
Changes in your vision
If you have diabetes, watch for signs of cataracts. These can include blurry vision, trouble seeing at night, and glare from lights.
You may also notice that colours look faded or dull.
Vision that keeps changing
Sometimes your glasses may not seem to work as well as before. Your vision may change often.
This can be a sign that something is affecting your lens.
If you notice these changes, it is important to get your eyes checked.
Can good control of diabetes help?
Managing blood sugar levels
Keeping your blood sugar levels stable can help protect your eyes. It may slow down the development of cataracts.
Good control also helps reduce the risk of other eye problems linked to diabetes.
Regular health checks
Seeing your GP or nurse regularly can help you manage your diabetes well. This supports your overall health, including your eyes.
Small steps can make a big difference over time.
How are cataracts treated?
When surgery is needed
Cataracts cannot be reversed with drops or glasses. The only way to remove them is with surgery.
Cataract surgery removes the cloudy lens and replaces it with a clear artificial lens.
What to expect from surgery
The surgery is quick and usually done in one day. Your eye is numbed, so you should not feel pain.
Most people notice clearer vision within days after surgery.
Is cataract surgery safe for people with diabetes?
What you need to know
Yes, cataract surgery is usually safe for people with diabetes. Many people with diabetes have this surgery every year.
However, your eye health will be checked carefully before surgery.
Why extra checks are important
Diabetes can also affect the retina, which is the back part of the eye. Your specialist will check for this before planning surgery.
This helps make sure you get the best result.
At My Eye Clinic in Gosforth, we take time to understand your full eye health before treatment.
Can vision improve after surgery?
What results to expect
Many people with diabetes see a big improvement after cataract surgery. Vision often becomes clearer and brighter.
However, if there are other eye problems caused by diabetes, these may affect your final vision.
Why early care matters
The earlier you treat cataracts, the better your chances of good vision.
Regular eye checks help catch problems early.
