Myopic arc is the most common fundus change in myopia. Many patients are treated with laser surgery and think about post-operative dietary modifications, but do not know where to start. The following is an introduction to what foods are appropriate for patients to eat after laser treatment of myopic arc? 1, food to minimize the pungent, sour, spicy ingredients, such as chili, ginger, garlic, onions, pepper, etc.. 2, to try to avoid eating shrimp, crab and other high-protein allergy-prone food, so as not to affect the whole body, and to try to avoid smoking and drinking. 3, to provide adequate vitamin A. Vitamin A is an important raw material for the composition of the eye photoreceptors, has the role of protecting the eyes and other epithelial tissues, and indirectly has the function of resistance to infection. Vitamin A is mainly contained in animal foods, such as animal liver, eggs, milk, cod liver oil, butter and other foods. In addition, carotene is a prerequisite substance for vitamin A, which can be converted into vitamin A in the body and is mainly contained in vegetables such as carrots, spinach, lettuce leaves, leeks, pumpkin, tomatoes and green beans. Adequate protein should also be supplemented. Excimer laser surgery is performed on the cornea. The laser ablates a portion of the corneal thickness to reduce the curvature of the cornea for the purpose of correcting myopia. The main component of the cornea is collagen, so to repair the corneal incision tissue and shorten the renewal time, we must properly supplement collagen and protein foods. 4, collagen-rich foods are lean pork, beef, lamb, chicken, duck, animal offal, fish, beans and soy products, etc. You should also add foods rich in vitamin B. If lack of vitamin B is prone to keratitis, symptoms such as tearing, redness and itching of the eyes, and even eye cramps. The nerves on the cornea are damaged after surgery, and vitamin B12 can encourage the recovery of the nerves on the membrane. Foods rich in vitamin B are animal liver, heart, kidney, egg yolk, cream and colored vegetables. Another thing is to supplement some trace elements, such as calcium, zinc, cadmium, molybdenum and selenium.
