Cataract refers to the degenerative change of optical quality caused by the decrease of lens transparency or color change in the eye. For cataract patients, the most effective cataract treatment is cataract surgery, but good cataract surgery needs postoperative conditioning, otherwise it will affect the effective rehabilitation of vision. So what should I eat after cataract surgery?

Patients who have just finished cataract surgery should choose liquid or semi-liquid food and fresh fruits and vegetables. Especially the elderly. The elderly have slow gastrointestinal peristalsis, which is easy to cause constipation. Therefore, we should eat digestible food and crude fiber food after operation to prevent overexertion during defecation, so that the local wound of the eye will bleed and the wound will split.

Eat more fresh vegetables and fruits rich in natural vitamin C after cataract surgery, such as celery, cabbage, green vegetables, tomatoes, strawberries, oranges and fresh dates. Eat more grains, green vegetables and lettuce, carrots and tomatoes, especially citrus fruits, grapes, lemons, bananas and apricots. Also eat some foods containing calcium often.

The dietary principles for long-term maintenance after cataract surgery include the following points:

1, you should eat foods rich in vitamin C.

Studies have shown that the lens of healthy people contains higher vitamin C, while the lens of cataract patients contains much less vitamin C.. The tomatoes, peppers, citrus fruits, kiwis, berries and cauliflowers we usually eat are rich in vitamin C, so cataract patients should eat more appropriately.

2. eat foods rich in vitamin e.

Vitamin E has a strong antioxidant capacity, which can reduce the changes and damage of oxygen free radicals to important components of cells, such as protein, nucleic acids, lipids and sugars. Foods containing vitamin E include peanuts, sesame seeds, lettuce, day lily, lean meat, milk, eggs and deep-sea fish.

3. Eat foods rich in lutein and zeaxanthin.

Lutein and zeaxanthin belong to carotene and belong to a large family of pigment complexes. These two pigments have strong antioxidant effect and bring beautiful yellow-green color to food. For example, corn, spinach, peas, kale, broccoli, zucchini and kiwi are all foods rich in lutein and zeaxanthin.

In addition, some dietary taboos should also be noted, so what can't you eat after cataract surgery?

Second, what can't I eat after cataract surgery?

First, strictly control alcohol and tobacco. Eating less fried, high-sugar, high-fat and high-cholesterol foods will have a certain negative impact on the recovery of surgical results, and patients should try to avoid it. You can't eat hard things, such as melon seeds and broad beans, and you can't eat irritating things, such as peppers and peppers.

Eat less or not eat fried food, artificial fat, margarine and animal fat, because these foods will accelerate the oxidation reaction and make people prone to cataracts.

Also pay attention to avoid eating dairy products rich in lactose, such as whole milk powder, milk, cream, cheese, ice cream and so on. For example, lactose contained in milk is decomposed into galactose by the action of lactic acid enzyme, and some people's metabolic ability to galactose in milk is reduced. In addition, galactose can interfere with the utilization of vitamin B2 in dairy products and make it deposit on the lens of the eyes of the elderly. Protein is prone to degeneration, which will reduce the transparency of the lens and easily induce or aggravate cataracts.
