Fixation Point in Crystalline 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 IOLMaster so that the fixation point lies between the images of crystalline lens and cornea. Then, repeat the measurement.

Reflections in Corneal Image

The lateral adjustment of the IOLMaster is not correct. Illumination reflections can be seen in the corneal image slit and the fixation point lies within the lens image.

Adjust the IOLMaster 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.
