• Das Goldmann Tonometer ist nach wie vor der Gold-Standard.
Dies entbindet den Anwender aber nicht vom Studium neuer
Publikationen zum Einfluss biomechanischer Parameter der
Hornhaut auf die Messung des Augen-Innendrucks.
• Le tonomètre Goldmann est toujours le standard d'or. Mais
cela n'empêche pas l'utilisateur d'étudier de nouvelles publica-
tions concernant l'influence de paramètres biomécaniques de
la cornée sur la mesure de la pression intra-oculaire.
• The Goldmann tonometer is still the gold standard. But this
does not prevent the user from studying new publications on
the influence of biomechanical parameters of the cornea on
the measurement of the intraocular pressure.
