There are no absolute dietary contraindications for the elderly after cataract surgery, but patients should eat a light diet. After cataract surgery, patients need to pay attention to eat easily digestible, rich in vitamins and fiber and other nutrients, such as spinach, pumpkin, milk, fungus, carrots, lean meat, corn porridge, bananas and so on. Elderly people need to follow the doctor’s instructions to eat after cataract surgery. After surgery, you can take moderate supplement of vitamin-rich foods, such as apples, bananas, spinach, carrots, kiwi, oleander, fungus and so on, which is helpful to the patients’ postoperative recovery. Patients can also consume some crude fiber foods in moderation, such as sweet potatoes, corn porridge, taro, oatmeal, pumpkin, dragon fruit, etc. These foods and fruits can accelerate peristalsis of the gastrointestinal tract, which helps to improve constipation. Patients should also take appropriate protein supplements, such as milk, walnuts, lean meat, chicken, etc., which help increase the body’s resistance so as to facilitate the healing of eye wounds after surgery. It is recommended that patients after cataract surgery follow the doctor’s instructions for care, regular review, and timely consultation when discomfort occurs.
