Patient: I had cataract surgery a few years ago and my vision recovered well after surgery, but now I can’t see well again, how should I treat it?
Li Mei, Ophthalmology Department, Peking University First Hospital: The most common cause of vision loss after cataract surgery is posterior cataract, which is caused by clouding of the capsule membrane supporting the IOL. Of course, there may be new problems in the patient’s eyes, and treatment should be tailored to each case. Please visit an ophthalmologist to determine the cause and treatment.
