The key to restoring normal vision after cataract surgery for diabetic patients depends on the patient himself, whether there is diabetic retinopathy in the fundus and the degree of the condition. If the patient already has retinal hemorrhage and exudation, or even proliferative retinopathy, vitreous hemorrhage or retinal detachment before surgery, in this case, even if the cataract surgery is very successful, the recovery of vision after surgery will not be ideal. In addition, because of the long-term metabolic disorder of diabetic patients, the body resistance is reduced and the recovery period of surgery is long, which is also the reason for the unsatisfactory vision after cataract surgery.
In conclusion, whether the vision can be recovered or improved to what extent after diabetic cataract surgery depends on the fundus function status of the patient’s operated eye itself and the diabetic control status. In some patients, vision is well recovered after surgery, but poor control of diabetes can lead to re-impairment of vision due to aggravation of fundus complications. Therefore, patients with diabetic cataracts still need strict blood sugar control and regular fundus examination after surgery in order to maintain the vision already obtained.
