Laser myopia surgery may have sequelae such as dry eye, secondary glaucoma, secondary cone cornea and retinal detachment. Laser myopia surgery is a commonly used treatment for myopia. Although the surgical technique is mature and relatively safe, there are still some patients who may suffer from sequelae and complications. Dry eye is a common after-effect of laser surgery, which is usually more obvious within half a year after the surgery, and can be relieved by itself after more than half a year after the surgery, which is related to the fact that the corneal sensory nerve fibers are cut off during the surgery, resulting in a decrease in reflex tear secretion. The occurrence of secondary glaucoma is related to the need to use hormone eye drops for a longer period of time after laser surgery. The occurrence of secondary cone cornea is related to the patient’s own thin corneal thickness and high myopia. The occurrence of retinal detachment, on the other hand, is related to the use of a negative pressure ring to attract the eye and immobilize it during the surgery, which causes irritation to the eye. Patients are advised to go to regular medical institutions for examination, choose the surgery under the guidance of professional doctors, and do not force the surgery if they do not meet the conditions of the surgery.
