The best age for myopia surgery is 18-50 years old, which is the general standard range. The main issue involved is the principle of myopia surgery versus the results of the surgery. The principle of myopia correction surgery is that a specific number of degrees of glasses are made on the cornea or in the eye through surgery. If the patient has 500 degrees of myopia before surgery, after the surgery, a 500 degree lens is made on the patient’s cornea or in the eye, and has the effect of a 500 degree lens. The degree of myopia surgery should be stable because after surgery, the effect of the specific degree on the eye is fixed, so the prerequisite for surgery is that the degree of myopia is stable before surgery. If you are too young, your myopia is not stable, it is still developing, and the prescription is still changing. If you are too old, your myopia will also change, the lens in your eye, will change by the age of 50 or more, and this will also affect the change in the myopia of your eye.
