(artifacts)
In the measurement of pseudophakic eyes, it may happen that images
produced at the front side of the intraocular lens are visible beside the
reflections from the cornea.
The reflections from the IOL are fainter and unsharp.
If no measurement is achieved after focussing the peripheral measuring
marks from the cornea move the instrument approximately 1 mm away
from the patient's eye (defocusing) and release the measurement. The
images produced at the cornea will be slightly larger, while the artifacts
of the IOL become fainter such that the evaluation process possibly does
not identify the IOL reflections as measuring points. If this procedure
does not succeed you cannot measure the corneal curvature.
