After cataract surgical treatment, the patient’s precautions mainly include postoperative local care, life management, dietary management, and review. The common types of cataract surgery include ultrasonic emulsification cataract aspiration, artificial lens implantation, etc. The prognosis is usually better after surgery. Patients should pay attention to follow the doctor’s instructions to continue medication to avoid infection of the surgical incision. For a short period of time after surgery, patients should avoid getting dirty water in the eyes and do not rub the eyes with their hands to avoid affecting the healing of the incision. There is no great restriction on the daily activities of patients, but they need to pay attention to avoid doing gravity physical activities, strenuous exercise, prolonged bowing of the head, breath holding and so on. Patients also need to pay attention to avoid excessive eye use, especially do not stay up late to look at cell phones, computers and other electronic devices. In terms of diet, patients need to pay attention to avoid stimulating food, avoid smoking and drinking, and focus on light, easy to digest, highly nutritious food. As the postoperative visual acuity is still unstable, patients need to review regularly, and if patients experience eye pain, sharp decline in vision and other uncomfortable symptoms, it is recommended that patients consult a doctor in a timely manner.
