Fig. 26b

The two red ring marks (3, Fig. 26a) on the side rails of the headrest are for rough vertical adjustment of the chin rest (3, Fig. 26b). The patient's eyes should be level with these marks.

In Overview mode, align the IOLMaster to the patient's eye using the joystick (1, Fig. 26a). Turn the control knob for vertical adjustment. Tell the patient to look steadily at the fixation point in the center.

Adjust the IOLMaster-to-patient distance until the 6 light spots (1, Fig. 26) appear focused. If possible, the 6 light spots should be centered on the cross hairs and the edge of the pupil/iris structure should appear in focus.

  IOLMaster software

The position of the IOLMaster in relation to the patient's eye, thus found, serves as a starting point for fine adjustments to be made in the respective measurement mode.

Measure Other Eye

Measurements of the other eye must be performed analogously to the previous eye.

IOLMaster Arizona After each change of side, the overview mode is automatically activated for coarse alignment.

Enter Next Patient
