Is cataract surgery dangerous?

summary

Cataract surgery as a whole is still very safe. At present, the success rate of cataract surgery is as high as 90%. The remaining 10% does not mean that there is a risk, but that there is no complete cure. Patients without retinopathy had a 100% success rate. If there is no retinal disease in patients with cataract, cataract surgery can even be said to be 100% success rate. However, there are risks in any operation, not to mention the operation inside the eyes. Is cataract surgery dangerous?

Is cataract surgery dangerous?

1. Contraindications of cataract surgery: Patients with other systemic diseases, such as hypertension, coronary heart disease, diabetes, can not tolerate surgery; If the patient's eyes and surrounding tissues have active inflammation, it is a temporary contraindication for surgery. 3. The patient has other eye diseases, such as retinal vascular occlusion, iris reddening, neovascular glaucoma, corneal opacity, iridocyclitis, severe corneal endothelial disease, severe macular disease, vitreous hemorrhage and optic nerve atrophy;

2. Although cataract surgery is already a very safe operation, no matter how safe it is, there will be risks. Although the probability is only one in a thousand, it is still a risk. The complications after cataract surgery are: bleeding after surgery, generally there is no problem, if there is choroidal hemorrhage, it will seriously affect the postoperative vision, even blindness.

3. Eye infection. There will be incision in the eye during the operation. If bacteria are brought into the incision, it will lead to endophthalmitis. This is a serious disease, that is, active treatment after the event, but still irreversible, the disease will seriously affect vision, and even cause blindness.

matters needing attention

According to the research of relevant scholars, the lens of patients with cataract has high cholesterol content, so the occurrence of cataract has a certain relationship with cholesterol, so the food with high cholesterol should be eaten less. Selenium is a semimetallic element, and the visual acuity is directly related to selenium. Selenium deficiency in human body can induce lens opacification and cataract. Therefore, we should eat more selenium rich food to prevent cataract. Such as: Asparagus, mushroom, grain, fish, shrimp, milk, meat, nuts
