Laser surgery for myopia mainly changes the diopter through the change of corneal thickness, so as to achieve the purpose of taking off glasses, but it can not completely cure myopia. If you don't want to wear glasses, your myopia is stable for more than two years, and you are healthy, you can consider going to the hospital. If you have to pass the examination to consider the cost of surgery, different hospitals and different surgical methods. ?

Extended data:

The relative contraindications of laser surgery are:

First of all, people with eye diseases should not have surgery. Some patients suffer from active inflammatory diseases, such as acute conjunctivitis, keratitis, dacryocystitis and corneal ulcer. These patients are prone to infection during surgery and have many uncomfortable symptoms after surgery. In addition, surgery is not recommended for patients with dry eye, glaucoma, trachoma and retinal diseases.

Others are scarred themselves, or suffer from diabetes and lupus erythematosus. These diseases easily affect the degree of wound healing, and the surgical effect is greatly reduced. If patients with the above diseases are forcibly treated, complications such as retinal detachment and keratoconus may occur soon after operation, which will seriously damage their vision.

Secondly, patients with high or thin cornea are not suitable for surgery. At present, most of the laser surgery on the market is corneal laser surgery. Because the operation is performed on corneal tissue, it is required that the patient's corneal thickness can withstand the correction of myopia.

The higher the patient's degree, the less corneal stroma remains. If the patient's myopia is too high or the cornea is too thin, the cornea can't bear the correction of myopia, and the risk of surgery will increase.

Finally,/kloc-patients under 0/8 years old are not suitable for surgery. Generally speaking, the eyeballs and corneas of teenagers under 18 are not fully developed and their diopters are not stable enough. Most people's eye development and myopia have not changed much in adulthood, so it is obviously much safer to have surgery in adulthood. In addition, severe amblyopia is not suitable for surgery.
