After laser surgery, if you don't protect your eyes, it's easy to rebound, and you can't do it again. Generally, I don't want to enter the military school. It is not recommended to do laser correction surgery. In addition, if you have to do it, you must be an adult to go to the provincial hospital. For example, a big fat man wants to lose weight, and it is too difficult to lose weight, so he goes for a meat cutting operation. If he cuts less, it won't work. If he cuts too much, he will be cut off and become a basket case. After the operation is successful, he will remain a fat man for some time without proper maintenance. In recent years, some hospitals have farsighted or even blinded patients' myopia.
