As we continue to navigate the scale and impact of COVID-19, the health and wellbeing of our staff and patients is always our greatest priority. We have therefore made the difficult decision to stop seeing non-urgent patients but will continue to offer support through video consultations.
Cataracts are cloudy patches that develop in the lens of the eye. They develop slowly over time, so older people are much more likely to be affected. The longer they are left to develop, the more severely cataracts can affect the clarity of your vision. If left untreated, cataracts can eventually result in blindness.
Cataract symptoms will worsen over time. You are likely to begin by experiencing cloudy or misty vision, as if everything is blurred. Unlike hypermetropia or myopia, where distance plays a part in how well you can see, with cataracts you will experience this blurred quality no matter how near or far away the objects that you are looking at.
Other cataract symptoms may include:
Cataracts are not painful, but it is important to get your eyes checked as soon as you begin to experience any of these symptoms. By getting seen sooner rather than later, you can limit the impact that cataracts will have on your vision
We don’t yet fully understand what causes cataracts, but there are a few risk factors that seem to make it more likely. The biggest of these are your age (older people are more likely to develop cataracts) and your genetic inheritance (if it runs in your family, you might be predisposed to suffer from the condition) but there’s not much you can do about these!
Other, more controllable cataract causes include:
There’s no guarantee that you will be able to prevent cataracts, which are extremely common in people over 60. But cataract causes and prevention are closely linked; there are a few things that you can do to reduce your chances of developing the condition, by addressing the risk factors associated with cataracts.
If these preventative measures come to nothing and you do develop cataracts, they can be easily treated with cataract surgery. This is a simple procedure that involves removing the cataract and inserting an artificial IOL (intraocular lens) to replace the natural lens. Each eye is treated separately, with a period of 1-2 weeks in between operations, but the procedure itself is very quick, lasting only 10-15 minutes.
One of our experts in cataract symptoms, causes and prevention, Allon Barsam has also pioneered femtosecond laser cataract surgery, a new type of bladeless cataract surgery that is even more efficient and effective than the traditional treatment.
