IOLMaster — Anterior Chamber Depth
Error Message.

Defocused Image

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.

Note: As a rule, a slight defocusing of the IOLMaster does not affect the anterior chamber depth measurement significantly.
