Title (EN) IMPROVEMENTS TO FITTING ORTHOKERATOLOGY LENSES
(FR) PERFECTIONNEMENTS APPORTÉS À L'AJUSTEMENT DE LENTILLES ORTHOKÉRATOLOGIQUES
Abstract:
(EN) A method for fitting OK lenses to a patient comprising the steps of: applying a corneal topography apparatus to a patient to capture baseline and post wear maps of a cornea of the patient in a computer to thereby derive a difference map; processing the difference map to fit Zernike polynomials thereto wherein weights of said fitted polynomials comprise features of a test feature vector for the difference map; applying the test feature vector to a classification machine trained to classify the difference map as one of a number of predetermined classes; and subsequently treating the patient taking into account the classification machine's classification.
(FR) L'invention concerne un procédé d'ajustement de lentilles OK à un patient comprenant les étapes consistant à : appliquer un appareil de topographie cornéenne à un patient pour capturer des cartes de ligne de base et après le port d'une cornée du patient dans un ordinateur pour ainsi dériver une carte de différences ; traiter la carte de différences pour y ajuster des polynômes de Zernike, les poids desdits polynômes ajustés comprenant des caractéristiques d'un vecteur de caractéristiques de test pour la carte de différences ; appliquer le vecteur de caractéristiques de test à une machine de classification entraînée pour classifier la carte de différences en tant que classe d'un certain nombre de classes prédéterminées ; et traiter ensuite le patient tout en tenant compte de la classification de la machine de classification.
