Any type of refractive surgery—be it laser or with intraocular implants—aims to correct the current myopia, which is done with great precision. However, currently there is no technique that can stop it from progressing. Therefore, surgery should be performed once the myopia is stable and the patient has gone a couple of years without any significant increase in their prescription.
Once stable, the majority of myopias do not tend to change in adulthood, although cases of higher myopia do change more often than those of simple myopia.
