IOLMaster — Anterior Chamber Depth
If the IOLMaster is not optimally focused, the image of the fixation point
becomes larger and fainter. At the same time, the images of the front edge
of the lens and/or the cornea may become so faint that they cannot be recognized.
In such a case, the system displays an "Error" message and
an explanatory text indicates which image details are either missing or could
not be recognized correctly.
Improve the focus adjustment of the IOLMaster and repeat the measurement. The
fixation point must be optimally focused.
As a rule, a slight defocusing of the IOLMaster does not affect the anterior
chamber depth measurement significantly.
