The operation can be performed at any age. Nevertheless, it is advisable to wait until the refractive defect has stabilized, normally in adulthood. Some defects may stabilize at an earlier age; and cases of severe myopia will often stabilize when the patient is older.
Stable sight defect
Correction of a sight defect that has not yet stabilized means that the defect may return, though to a lesser degree. To ensure that the result is constant and will last in time, surgery must be performed when the sight defect is stable: if your defect does not change for at least one year (better still, for 18 or 24 months), it can be classed as stable and laser correction can be considered.
With laser treatment, it is essential that the cornea thickness is at least the minimum required for treatment. The corneal thickness must be measured by an eye doctor during the specialist refractive eye examination.
