Cataract is the number one blindness-causing eye disease in the world. With the continuous development of cataract surgery technology, the safety of cataract surgery has been improved, and the elderly no longer need to suffer from the pain of “old eyes”, and the quality of life has been greatly improved. However, many seniors have questions and are concerned about recurrence after cataract surgery. The following is a unified explanation and explanation. 1. After cataract surgery, it will not recur. 2. After cataract surgery, the membrane of the capsule may become cloudy again, which we call “posterior cataract”. The younger the person, the higher the incidence. In children, this happens 100% of the time; it is also related to systemic diseases and localized diseases of the eye. 3. If you have “posterior cataract” and it obviously affects your vision, you can have laser treatment in an outpatient clinic, which is relatively simple and does not require re-operation or hospitalization.
