To perform the measurements individually, simply click on one of the “AL” (axial length), “ACD” (anterior
chamber depth) or “KER” (keratometry) buttons.
WARNING: a correct ACD measurement cannot be made without acquiring the patient's
keratometry.
Caution should be practised when using the device’s ACD measurement for any given intraocular lens
calculation because of the high variability of this measurement.
The ACD measurement is the distance between corneal epithelium and the crystalline lens surface.
Pupillometry
Selecting the "Pupillometry" button gives access to the environment for the acquisition of the following
measurements:
Dynamic pupillometry
Photopic pupillometry
Mesopic pupillometry
13.5 Full biometry acquisition (K-AL-ACD)
Figure 34
This is a special mode which successively performs all the measurements described in detail in the following
paragraphs, specifically:
- Axial length measurement
- Anterior chamber depth
