Apparatus and method for subjectively refining a corrective prescription based on feedback from a patient. Subjective refinement of a corrective prescription is accomplished by measuring aberrations of a wavefront emanating from the eye, computing a proposed corrective prescription based on the measured aberrations presenting to the patient an image reflecting the proposed corrective prescription, and varying the proposed corrective prescription based on feedback from the patient through an input device coupled to the processor to obtain the preferred corrective prescription.

L'invention concerne un appareil et un procédé permettant d'affiner subjectivement une ordonnance de correction en fonction de la rétroaction d'un patient. Cet affinement subjectif d'une ordonnance de correction est appliqué par le biais de la mesure d'aberrations d'une surface d'onde émanant de l'oeil, par le calcul d'une ordonnance de correction proposée en fonction d'aberrations mesurées, et par la présentation au patient d'une image reflétant l'ordonnance de correction proposée, puis par la variation de l'ordonnance de correction proposée en fonction de la rétroaction du patient, par le biais d'un dispositif d'entrée relié au processeur pour obtenir l'ordonnance de correction préférée.
