When myopia surgery fails, it may not be able to achieve the effect of vision correction, which can be determined according to their own conditions, and those who are eligible can have a second surgery or take good care of their eyes. Currently, the commonly used method of myopia surgery is the femtosecond laser surgery method. The surgeon will design a surgical plan according to the individual’s condition before the surgery, which can usually correct the vision well. If the surgical plan is not properly designed, resulting in poor vision correction, overcorrection or undercorrection, etc., the vision can be corrected again through a second surgery. Failure of myopia surgery can also be caused by infections due to improper postoperative care. Refractive error can be caused by early use of electronic devices, lack of eye care leading to infections, etc. Attention should be paid to the prevention of eye infections and the reduction of the frequency of the use of electronic devices.
