Zusammenfassung
Eine neue Methode zur Bestimmung intraokularer Distanzen in vivo wurde entwickelt. Sie beruht auf einer interferometrischen Technik mit teilkohärentem Licht in Verbindung mit dem Doppler-Prinzip. Die Methode wird am Beispiel der Messung der Achsenlänge des Auges demonstriert. Vergleichsmessungen mit der Ultraschalltechnik zeigen eine gute Übereinstimmung. Die Vorteile der neuen Technik liegen in der Berührungsfreiheit und der höheren Genauigkeit.
Summary
A new method for determining intraocular distances has been developed. It is based on interferometry methods using partially coherent light in conjunction with the Doppler principle. The method is demonstrated in the case of axial eye length measurement. Comparisons with the ultrasound technique yield a good agreement. Avoiding mechanical contact between eye and instrument and achieving a higher precision are the main advantages of the new technique.
