If you have 500 degrees of myopia, you will not be able to serve in the military without myopia surgery, because the requirement of the military medical examination is generally above 0.8. 500 degrees of myopia, you can choose to do full femtosecond or half femtosecond surgery, as long as the corneal thickness and corneal conditions allow the case. If you don’t want to do the surgery, but just want to cope with the medical examination, 500 degrees of myopia can choose to wear keratoconus in advance. However, after the physical examination, you may still need to choose a time to have your myopia done. The current requirements for military medical examinations do not list patients who have had myopia surgery as not being able to serve in the military. As long as there are no relevant lesions in the fundus, there will not be much of a problem.
