Femtosecond surgery is a relatively advanced surgical method used to treat myopia, with a high degree of surgical precision and therefore the surgical results are better. However, since it is an invasive operation, rare risks or complications will inevitably occur, mainly including the following: first, overcorrection and undercorrection; second, refractive regression; third, dry eye after surgery; fourth, optical-related competent claims such as glare and halos; fifth, infectious keratitis; sixth, progressive corneal dilation; and seventh, corneal neovascularization. These are some of the common complications of femtosecond laser surgery, and the chances of these complications are usually relatively small and preventable and controllable, so they do not affect the surgical treatment. So if myopia exists in the eye, it can be treated by femtosecond surgery.
