What are the risks and sequelae of myopia surgery?

Excimer and femtosecond laser refractive surgery, due to the different healing ability of the wound, may show residual myopia, hyperopia or partial refractive regression. There are also many people who will show dry eye symptoms. If you do not pay attention to hygiene, it is easy to show corneal infection after surgery. In addition, people with high myopia show retinopathy that cannot be changed by surgery.
