Diagonal view alignment
Perform the diagonal view alignment while monitoring Diagonal view
alignment screen shown in the display.
When the display shows their position as shown in this picture, laser beam is hitting the
iris and background lights are not distributed evenly which would cause false
measurements.See Fig. 6 and re-align.
When the display shows their position as shown in this picture, there is no window
between two laser beams and the Measurement point is placed far away from the ante-
rior chamber which would cause false measurements. See Fig. 6 and re-align.
Diagonal view of the patient’s eye is shown in the display.Laser beam is emitted and
Measurement window is shown in the display. Use Joy stick to position Measurement
window and Reflected lights as shown in Fig. 5 (OK) (see Fig.7).
