A qualifying examination is a basis of every laser vision correction. During the examination multiple tests are performed in order to determine any medical contraindications and the most suitable method of correction. As a matter of fact, elimination of the contraindications minimises the chance of occurrence of any side effects. Our laser can operate on wide range of refractive errors (-14 up to +6). The surgery results in a best possible correction – you can see as if you were wearing glasses, without actually having them on. It is possible to treat your refractive error by means of laser vision correction. Regarding your hypothyroidism, in order to be qualified for the surgery you have to have a medical statement from your endocrinologist that there are no contraindications for the surgery, that the hormones are indeed stable and that you are under constant medical supervision. Hypothyroidism substantially elongates the healing process.
