Title (EN) A METHOD TO QUANTIFY THE QUALITY OF CORNEAL DONOR TISSUE FOR TRANSPLANTATION USING TOMOGRAPHY IMAGING
(FR) MÉTHODE POUR QUANTIFIER LA QUALITÉ D'UN TISSU DONNEUR DE CORNÉE À DES FINS DE GREFFE À L'AIDE DE L'IMAGERIE PAR TOMOGRAPHIE
Abstract:
(EN) The invention discloses a method for evaluation and quantification of the quality of a corneal donor tissue for transplantation using the optical tomographic imaging. The method is used for the analysis of corneal parameters i.e. not only the physical paramaters such as anterior or posterior surface of the cornea but also the underlying pathologies such as pre-existing refractive surgeries. The method is performed without the necessity of removal of the corneal donor tissue from the sealed container or the storage bottle of corneal storage medium. The corneal donor tissue is scanned using optical tomography imaging device, which captures the two-dimensional images of the corneal donor tissue and the images are acquired at different meridians. The acquired images are analyzed for features of the corneal donor tissue for qualitative parameters. The method is useful for analysis of quality of corneal donor tissue for pre-existing refractive surgeries and corneal inflammation/infections.
(FR) L'invention concerne une méthode d'évaluation et de quantification de la qualité d'un tissu donneur de cornée à des fins de greffe à l'aide de l'imagerie par tomographie optique. La méthode est utilisée pour analyser les paramètres cornéens, à savoir non seulement les paramètres physiques tels que surface antérieure ou postérieure de la cornée mais également les pathologies sous-jacentes telles que chirurgies de réfraction préexistantes. La méthode est mise en œuvre sans qu'il soit nécessaire d'enlever le tissu donneur de cornée du récipient scellé ou de la bouteille de stockage contenant un milieu de stockage cornéen. Le tissu donneur de cornée est scanné à l'aide d'un dispositif d'imagerie par tomographie optique, qui capture des images en deux dimensions du tissu donneur de cornée et les images sont acquises à différents méridiens. Les images acquises sont analysées pour identifier les caractéristiques du tissu donneur de cornée en ce qui concerne ses paramètres qualitatifs. La méthode est utile pour analyser la qualité d'un tissu donneur de cornée et identifier des chirurgies de réfraction et des inflammations/infections de la cornée préexistantes.
