Reasonable nutritional supplement in diet after myopia surgery is helpful to delay and prevent the development of myopia. You can eat more foods rich in lutein, such as kiwi fruit, blueberry, spinach, etc., which can nourish the retina and relieve visual fatigue. You can also eat more foods rich in vitamin A, such as animal liver, carrots, meat, eggs and so on. It also has the function of nourishing the retina. Calcium supplementation can increase the strength of sclera and prevent axial elongation, thus delaying the progress of myopia. For example, you can eat more dairy products. Myopia patients should not eat too sweet food and starchy food. Because after excessive intake of sweets, high-sugar diet will soften the sclera, and in the process of consuming sugar in the body, a lot of vitamin B 1 may be consumed, and the calcium content in the body may be reduced. Vitamin B 1 is a protective agent of optic nerve, and its content will affect the function of optic nerve. Calcium is also a protective agent for eyes. In addition, eating more starchy foods is not good for myopia, which may be related to the growth of axial length, which may easily lead to the aggravation of myopia.
