Image of fixation point in image of crystalline lens
Fig. 69 Fixation point lying in lens image
If the image is laterally misaligned, it may happen that the image of the
fixation point is lying within the lens image.
Position the instrument so that the fixation point lies between the
images of crystalline lens and cornea. Then, repeat the measurement.
Reflections in the corneal image
Fig. 70 Reflection in corneal image due to lateral maladjustment
The lateral adjustment of the instrument is not correct. In the corneal
image slit illumination reflections can be seen and the fixation point lies
within the lens image.
Adjust the instrument laterally until the corneal image is undisturbed.
As a rule, the fixation point will then be between the image of the
anterior lens and that of the cornea. Repeat the measurement.
