The invention provides correction of wavefront aberrations of the eye that take into account fluctuations in the aberrations due to biophysical rhythms. Correction is provided for an intermediate value of these fluctuations of the wavefront aberrations. This intermediate value is determined by extrapolating a wavefront measurement to predict the overall variation. The final correction is determined using a weighting scheme derived from the clinical comparisons of the frequency and amplitude components of the variations.
L'invention porte sur un procédé de correction d'aberrations du front d'onde de l'oeil tenant compte des fluctuations des aberrations dues aux rythmes biophysiques. La correction correspond à une valeur intermédiaire de ces fluctuations des aberrations du front d'onde. La valeur intermédiaire est déterminée par l'extrapolation d'une mesure du front d'onde permettant de prévoir la variation globale. La correction finale est déterminée au moyen d'un calcul pondéral obtenu à partir des comparaisons cliniques des composantes d'amplitude et de fréquence des variations.
