What are the complications of laser myopic surgery?

Laser is used for myopia, the main principle is to reduce the thickness of the cornea, change the refractive power of the eye, need to do a pedicled corneal flap on the surface of the cornea, remove the convex lens shape of the cornea below the corneal flap, can make the eye corrected vision to normal. In addition, the corneal flap is in a free state. If it shows strenuous exercise after surgery, it can cause corneal flap displacement. Individual patients can also show dry eyes after surgery, mainly due to the decline of corneal epithelial secretion function.
