Title
(EN) PROFILING CALIBRATION PLATE
(FR) PLAQUE D'ETALONNAGE SERVANT A DETERMINER UN PROFIL
Abstract
(EN)
This invention is a profiling, and/or calibration sample plate (22) allowing approximately full scale calibration monitoring of an ablation achieved in corneal tissue allowing a permanent record of an achieved corneal ablation to be made immediately before (and/or during) the actual cornea to be ablated is ablated. One exemplary profiling/calibration sample plate (22) includes a plate (or other shape) having a recess (36) adapted to contain a cross-linked collagen material (38). A non-contact interferometer (24) may be used to measure the resultant or achieved ablation profile on the surface of the cross-linked collagen material (38) contained in the profiling/calibration sample plate (22). The measured surface features in the collagen material (38), and/or a preserved original or copy of the cross-linked collagen material (38) may be maintained as a permanent record of the actual ablation performed on a particular patient.
(FR)
L'invention concerne une plaque (22) servant à déterminer un profil et/ou à étalonner un spécimen, ce qui permet de contrôler l'étalonnage sur une échelle pratiquement totale d'une ablation effectuée dans le tissu de la cornée et d'obtenir une indication permanente d'une ablation cornéenne à effectuer immédiatement avant (et/ou pendant) l'ablation réelle de la cornée sur laquelle on doit pratiquer une ablation. Selon un exemple, cette plaque (22), qui peut également se présenter sous une autre forme, possède un évidement (36) conçu pour contenir un matériau (38) à base de collagène réticulé. On peut utiliser un interféromètre (24) sans contact afin de mesurer le profil d'ablation obtenu sur la surface de ce matériau (38) contenu dans la plaque (22). On peut conserver, en tant qu'information permanente de l'ablation réelle effectuée sur un patient déterminé, les mesures des caractéristiques de surface du matériau (38) à base de collagène et/ou d'un original ou d'une copie préservée de ce matériau.
