There is a lens inside the eye behind the coloured iris that helps focus light. If this internal lens becomes cloudy it is called a cataract. If you develop a cataract your vision becomes progressively blurred. You may also notice that you are easily dazzled by bright lights, and that colours become washed-out or faded. These symptoms may be caused many other conditions and a thorough examination is needed to be sure of the diagnosis.

The development of cataracts over time is very common and is considered normal. Progression is usually slow, and can be likened to the greying of our hair as we get older. Sometimes a cataract develops at an earlier age due to an injury to the eye, other health problems, or following the use of certain medicines.


New spectacles may help because cataracts often alter the focusing of the eyes, but in time vision cannot be corrected satisfactorily with spectacles. There are no medicines, eyedrops or lasers that can treat cataracts. The only treatment is an operation to remove the cloudy lens and replace it with an artificial plastic lens (an intraocular implant). This procedure is very common, but it is surgery that involves cutting into the eye and so always has an element of risk.

At Johnson & Furze we have a lot of experience dealing with cataracts. The first thing we do is to offer certainty of diagnosis that any reduction in vision is not being caused by any other condition like age-related macular degeneration, which needs very different treatment. It is not enough to simply notice that there is a cataract. We have to exclude other conditions that might also be present.

We then determine whether you have an increased risk of complications due to other features of your eye or general health, and if other conditions might limit improvements in vision. This is called a risk/benefit assessment, and may be very different for people with the same amount of cataract.


After these investigations we are well-placed to discuss whether now is the right time to have cataract surgery. It is important to have this conversation with someone you trust. We can offer advice, but you have the final choice. It is our job to give you the best information to help you make the decision that is correct for you. Because of experience in medical clinics, we are able to talk you through the procedure, what to expect on the day of surgery and during the recovery period.
