4) Entry boxes for the acoustic velocities required for the measurement
conditions currently set appear. Enter the converted acoustic velocity for the
examined eye using the software keyboard being displayed at the same time.
5) Touch the “Ent (enter)” key to apply the setting and proceed to the next
entry box.
6) Selecting an IOL material and touching the “Setting Change” button (2)
shows it in the IOL material field (3). The entry can be changed in the
setting change screen.
7) Touch the “Incorporate in L” button (4) or “Incorporate in R” button (5) to
apply the data entered for the eye to the other eye. Touch the “Initial
Setting” button (6) to enter the initial settings.
