Title
(EN) METHOD AND APPARATUS FOR MULTI-LEVEL EYE REGISTRATION
(FR) PROCÉDÉ ET APPAREIL POUR L'ALIGNEMENT D'ŒIL MULTINIVEAU
Abstract
(EN)
A method for performing multi-level eye registration comprising: obtaining a first initial reference eye image by a first diagnostic device and defining a reference coordinate system; obtaining a second eye image by a surgery device, said second eye image being obtained in a pre-surgery phase before the surgery has started; performing a first registration between said first eye image and said second eye image to obtain a first registration result; obtaining a third eye image by said surgery device, said third eye image being obtained after surgery has started; performing a second registration between said second eye image and said third eye image to obtain a second registration result; combining said first and second registration results to obtain a combined registration result to thereby obtain a registration between said initial reference eye image obtained by said diagnostic device and said third eye image obtained by said surgery device after surgery has started.
(FR)
La présente invention concerne un procédé pour effectuer un alignement d'œil multiniveau comprenant : l'obtention d'une première image d'œil de référence initiale par un premier dispositif diagnostique et la définition d'un système de coordonnées de référence; l'obtention d'une deuxième image d'œil par un dispositif de chirurgie, ladite image de deuxième œil étant obtenue dans une phase pré-chirurgie avant que la chirurgie ait commencé; la réalisation d'un premier alignement entre ladite première image d'œil et ladite deuxième image d'œil pour obtenir un premier résultat d'alignement; l'obtention d'une troisième image d'œil par ledit dispositif de chirurgie, ladite troisième image d'œil étant obtenue après que la chirurgie ait commencé; la réalisation d'un deuxième alignement entre ladite deuxième image d'œil et ladite troisième image d'œil pour obtenir un deuxième résultat d'alignement; la combinaison desdits premier et deuxième résultats d'enregistrement pour obtenir un alignement entre ladite image d'œil de référence initiale obtenue par ledit dispositif de diagnostic et ladite troisième image d'œil obtenue par ledit dispositif de chirurgie après que la chirurgie ait commencé.
