Laser eye surgery for myopia has its corresponding risks, such as the possibility of postoperative dry eye, myopia regression, secondary glaucoma, secondary cone cornea and so on. Laser corrective myopia surgery is a common treatment for myopia, including excimer laser surgery, semi-femtosecond laser surgery, full-femtosecond laser surgery and other surgical methods. Although the surgical technology is very mature, there is still a risk of complications that may jeopardize the health of the eyes. For example, patients may develop dry eye due to corneal hyperalgesia, secondary glaucoma due to prolonged use of hormone eye drops, or secondary cone cornea due to thin corneal thickness after surgery. In addition, if patients do not pay attention to the reasonable use of the eyes after the surgery, it may lead to myopia regression. It is recommended to go to the ophthalmology department in time if there is any discomfort after myopia surgery, so as to avoid delaying the condition.
