What are the side effects of myopia surgery?

The side effects of myopia surgery mainly include medical adverse reactions, such as corneal dilation, keratoconus, corneal opacity, corneal infection, dry eye syndrome, etc. The optical side effects are mainly reduced visual quality after surgery, which may lead to the increase of high-order aberrations such as aberration and spherical aberration, and the decrease of night vision after surgery, glare, and light overflow.
