Ophthalmic instruments - Corneal topographers (ISO 19980:2005)

ISO 19980:2005 is applicable to instruments, systems and methods that are intended to measure the surface shape of the cornea of the human eye.
It is not applicable to ophthalmic instruments classified as ophthalmometers.
ISO 19980:2005 defines certain terms that are specific to the characterization of the corneal shape so that they may be standardized throughout the field of vision care and have common meaning for all those who have occasion to participate in this area.
ISO 19980:2005 specifies minimum requirements for instruments and systems that fall into the class of corneal topographers. It specifies tests and procedures that will verify that a system or instrument complies with the standard and so qualifies as a corneal topographer in the meaning of this International Standard. It specifies certain tests and procedures that will allow the verification of capabilities of systems that are beyond the minimum required for corneal topographers.

Ophthalmische Instrumente - Hornhauttopographen (ISO 19980:2005)

Diese Internationale Norm gilt für Instrumente, Systeme und Methoden, deren Zweck in der Vermessung der Oberflächenform der Hornhaut eines menschlichen Auges liegt.
ANMERKUNG   Diese Messungen sind Messungen der Oberflächenkrümmung in bestimmten Bereichen, dreidimensionale topographische Messungen der Oberfläche oder andere globale Parameter, die eine Oberfläche charakterisieren.
Sie gilt nicht für ophthalmische Instrumente, welche in die Klasse der Ophthalmometer fallen.
Diese Internationale Norm legt bestimmte Begriffe fest, die im Zusammenhang mit der Charakterisierung der Hornhautoberfläche eine spezielle Bedeutung haben und für die daher eine einheitliche Festlegung für das gesamte Gebiet der Augenheilkunde und alle mit der Materie befassten Personen naheliegend ist.
Diese Internationale Norm legt die Mindestanforderungen an Instrumente und Systeme, die in die Klasse der Hornhauttopographen fallen, fest. Sie definiert Prüfungen und Verfahren, die belegen, dass ein System oder Instrument der Norm entspricht und so als Hornhauttopograph im Sinne der vorliegenden Internationalen Norm gilt. Sie legt weiterhin Prüfungen und Verfahren fest, die die Überprüfung der Technik von Systemen erlauben, die über den Mindestanforderungen für Hornhauttopographen liegen.
