OBJECTIVE OPERATIONS
Centering and photography
The centering operation is done with the control lever.
For details about the movement/adjustment of the instrument body with the control lever, see
the "MEMO" on page 49.
1 Hold the control lever and pull the instrument backwards toward the operator. As the ante-
rior segment fixation target flickers, instruct the patient to look at the fixation target.
Observe the anterior segment image on the color LCD monitor.
2 Using the control lever, move the instrument body in all directions to get the patient's eye
in the center of the color LCD monitor.
3 On the color LCD monitor, bring the ( ) scale to the patient's pupil, and make sure that the
pupil is larger than the ( ) scale.
For details about dilation, see the "MEMO" on page 50.
4 Slowly bring the instrument closer to the patient; the fundus image appears on the color
LCD monitor.
5 In this instance, the ( ) scale on the color LCD monitor moves to an alignment position cor-
responding to the picture position. At the same time, the anterior segment fixation target is
changed to the internal fixation target.
