The need for cataract surgery for people in their 80s also depends on their vision and the extent of the cataract. Generally, the older the person is, the more severe the cataract is, but there is one phenomenon that varies from person to person. Some people are 60 years old, but their cataracts are so severe that they are ready for surgery. However, even at the age of 80, the cataract is not so severe and the vision is better, so it can usually be observed first. Therefore, even for an 80-year-old, it depends on the existing vision and the degree of clouding of the lens. If the visual acuity is better than 0.5 and there is not much impact on the self-perception, observation can be done first. If the vision is already below 0.5 and the degree of cataract is so severe that you feel a white mist obscuring your vision, then cataract surgery can be considered. The current cataract surgery is also a relatively mature surgery, and most people will have improved vision after surgery.
