The lens in our eye which is responsible for adjusting our focus becomes less transparent as we get older. This change can take the form of a general haziness of the lens or areas in the lens may develop which do not allow the light to pass though properly. The lens also loses its ability to change shape so it becomes less able to change focus. By the time we are 50 most of us will have found that we can no longer read well without the help of spectacles. These changes in the lenses are normal. So it is normal at some stage to need help to see close things clearly and it is normal to develop cataracts. By the time we are over 70 most us us will have developed cataracts. The good news is that something can be done to help. An eye surgeon can exchange a lens with a cataract for a new , clear lens. Even better news perhaps, is that most of us who develop cataracts will never need treatment. Providing we can cope with the blurring caused by the cataract, because it is not bad enough to interfere with our quality of life, we don’t need to do anything about it. But if it does interfere with out quality of life and we can not see well enough to do the things we want to do, for example drive our car, we may decide that we want to do something about it. Then it is time to ask an eye surgeon for help. Although our eyes are very sensitive, cataract surgery is not normally uncomfortable. It is usually done under a local anaesthetic and doesn’t require an overnight stay in hospital. The techniques involved are very sophisticated and great care is taken to get the best result possible. There is a small risk of complications, as there is with any surgery, but with careful management these risks are kept to a minimum. The improvement in vision following cataract surgery is extraordinary. The world becomes bright and clear again and surprisingly colourful. If you are worried that your vision is being affected by cataracts, come and see us, we can help.
