The elderly can undergo cataract surgery if their general condition permits and there are no obvious contraindications in their eye condition after preoperative examination.
Cataract is a disease in which the lens changes from transparent to cloudy. According to the causes, it can be categorized as senile, congenital, traumatic, drug-induced, etc., among which the most common one is senile cataract.
Age-related cataract, as the name suggests, is a clouding of the lens caused by aging, and most patients are middle-aged or elderly. The general condition of the eye is a prerequisite for surgery, and the blood pressure of patients with hypertension, the recent heart status of patients with heart disease, and the fasting glucose value of diabetes mellitus need to be evaluated.
The general condition of the eye, such as the amount of corneal endothelium, the degree and hardness of lens clouding, and the condition of the fundus should also be evaluated.
Cataract surgery can be performed if there is no significant abnormality in the general condition and preoperative eye examination.
