Your eye’s lens focuses the light that enters your eye onto your retina, allowing you to see clearly. This lens is located behind your pupil (the black opening in the centre of your eye, which allows light to pass into your retina).
Ageing and certain conditions can affect the structure of the protein that forms your eye lens. As a result, cloudy patches can develop on your lens, which can negatively affect your vision. This clouding of your lens is known as a cataracts. It can impact one or both eyes.
What causes cataracts?
Ageing plays a part in the development of cataracts. But you can also develop cataracts following the use of steroid medication, eye injury, radiation exposure, or due to chronic diabetes.
What are the different types of cataracts?
There are three primary types of cataracts: a nuclear cataract, subcapsular cataract and cortical cataract. A nuclear cataract can develop in the middle of your lens, causing blurred vision and myopia (shortsightedness).
A subcapsular cataract can form in the back of your lens. It can also lead to blurred vision and often affects people with diabetes, or those taking oral steroid medication.
A a cortical cataract can cause cloudy patches on the edges of your lens, which can eventually spread towards its centre. It can impact both your near and distant vision.
At BMI The Priory Hospital in Birmingham, our dedicated team of eye specialists can diagnose and treat your vision problems.
If you are diagnosed with cataracts and would like to consider cataract removal surgery, your Ophthalmologist will explain what this will involve, including the risks, benefits and what to expect during your procedure.
