Corneal replacement is not required for myopic eyes. Corneal transplantation is only used for more serious corneal diseases such as corneal scarring, corneal ulcers or cone corneas. For myopia, corrective vision can be improved through surgery, which involves artificially cutting the corneal stroma and changing the refractive state of the cornea through surgical procedures, including excimer laser or femtosecond laser, in order to improve vision. This kind of surgery has been commonly used in the clinic, and the technology of surgery is also relatively mature, the incision is very small, so the recovery is also relatively fast, generally about 1 month after surgery, the vision can be completely restored to normal, and does not affect life and work. So after myopia appears, in addition to maintaining reasonable eye habits and wearing glasses, you can consider surgery to correct it. However, this surgery is a relatively delicate surgery, so you must go to a regular hospital for treatment.
