Is cataract surgery dangerous for 80-year-olds?

Cataract is caused by lens opacity in the eye. At present, there are two kinds of cataract surgery methods, one is phacoemulsification extraction, the other is extracapsular extraction. The patient is 80 years old at present. It is necessary to consider whether the patient has cardiovascular disease, diabetes and other diseases. If the physical quality is good and there is no such basic disease, any operation has risks, but the current operation must be lower than the risk of future operation.
