I have been asked what happens during cataract surgery. Immediately behind the pupil in our eye is a living lens. which is clear when we are born and becomes cloudy a we age. At a certain level of cloudiness it is called a cataract and a denser level of cloudiness it needs to be removed. Under local anaesthetic the surgeon makes a very small cut in the eye, removes the old lens and replaces it with a new,clear plastic one. Typically after about six weeks you would return to your optometrist to check everything has settled down well and to get new glasses.
It’a a modern miracle!
