Explanations
3rd axial length measurement
(22.55 mm) selected.
The axial length graph of this
measurement is displayed.
Unreliable result
1.6 < SNR < 2.0
SNR = SignalĆtoĆNoise Ratio
"Borderline SNR" appears
above axial length graph.
The result should be examined
by the user for validity.
Erroneous result
SNR < 1.6
"Error!" appears above axial
length graph.
Result has been manipulated.
* Remains displayed even if
manipulation was undone!
