1, eat more foods rich in vitamin C. Vitamin C can provide nutrition for retina and avoid being damaged by ultraviolet rays in daily life, so patients should prevent cataracts from happening again after operation. You need to eat more tomatoes, peppers, citrus fruits, kiwis, berries and broccoli. These foods are rich in vitamin C and should be eaten properly.

2. Eat more foods rich in vitamin E. Vitamin E is a nutrient with strong antioxidant capacity, which can delay cell aging. The foods containing vitamin E that cataract patients can usually eat are peanuts, sesame seeds, lettuce, day lily, lean meat, milk, eggs, deep-sea fish and so on.

3. Eat foods rich in lutein and zeaxanthin. Lutein and zeaxanthin have a strong antioxidant effect, delaying vision loss, and are indispensable nutrients for eyes. Patients can eat more foods rich in lutein and zeaxanthin, such as corn, spinach, peas, kale, broccoli, zucchini, kiwi and so on.

4. Drink tea often. Tannic acid in tea also has antioxidant effect on human body. The oxidation reaction in cataract patients leads to free radicals acting on the lens, so drinking tea often can prevent cataracts.

5, avoid eating fried, sweet and greasy dairy products, high-salt foods. Mainly because fried food will accelerate the oxidation reaction of the body, galactose will interfere with the utilization of vitamin B2 in dairy products, leading to the decrease of lens transparency and inducing or aggravating cataract; In normal times, people who eat a lot of salt are also prone to increase the risk of cataracts.

6. Limit calorie intake. Clinically, it is found that the incidence of some obese people is high, mainly because obese bodies will produce too much C-reactive protein, which can increase the incidence of cataract. Therefore, patients after cataract surgery should limit their intake of fat and calories to avoid obesity and affect their rehabilitation.
