The hazards of laser myopia correction mainly refer to the postoperative complications, which usually include dry eye, postoperative glare, cone cornea and so on. 1. Dry eye syndrome: usually laser surgery cuts corneal tissue to produce lenses, thus changing the refractive state of the cornea to achieve the purpose of myopia correction. When patients undergo corneal laser treatment, the corneal nerve endings may be injured, resulting in dry eyes. 2. Conical cornea: Because corneal laser myopia correction surgery will cut the cornea of the patient, the cornea of the patient becomes thinner after the operation, and the patient may have conical cornea after the operation, that is, the cornea is inflated, which can seriously damage the vision of the patient. 3. Postoperative glare: The patient’s pupil will naturally dilate at night, and when the edge of the dilated pupil overlaps with the edge of the cut cornea, postoperative glare will occur. It is recommended that patients follow the doctor’s instructions for care after myopia surgery, have regular checkups, and consult the doctor in time after discomfort occurs.
