It is not possible to correct too much or too little. It is possible that the cornea responds more or less to the treatment. This can leave a residual value.
The strength does not necessarily have to be “0” for good visibility.
It can especially occur in people with the higher abnormalities of the eye. Usually the strength is corrected just too little during the treatment. Often this has to do with your body’s response to the treatment.
Geen probleem. Je kunt ten alle tijden de test opnieuw doen om een nieuwe calculatie te starten.
