The stability of a refractive error is one of the most important parameters which either qualify or disqualify you from a laser vision correction procedure. To guarantee permanent results the surgery may only be conducted in case of a stable refractive error (with changes not greater than 0,25 to 0,5 dioptre per year). You should make an appointment for a preliminary qualifying examination and bring your previous examination results so that the doctor can assess the dynamics of your error progression.
