Selecting an IOL Group
You may want to select lenses from a different group. To
access one of the available IOL groups press the button
beneath the "Select IOL Group" selection. You can then
scroll through the list of IOL Groups. Stop when you
have reached the correct group. (Refer to
"How to Set

You may want to change the formula used to calculate
the IOL. To scroll through the list of available formulas
press the button beneath "Select Formula" selection.
The IOL constant used by the currently selected formula
is highlighted as white text on black background for each

Entering an ACD Value with the Haigis Formula
The Haigis formula uses the measured ACD or
calculated ACD value, as well as the axial length (AXL).
The ACD is shown in the measurement history list, and
an ACD field is added where the user can specify a
calculated or manually entered ACD. ACD should be
calculated for Aphakic and Pseudophakic eye types.
The other formulas do not use the measured ACD field in
any way and the field is only shown when Haigis is
selected or the formula compare mode is on.
Specify the ACD value by allowing the Accutome A-Scan
Plus to calculate (Calc) the value or manually enter the
value.
To manually enter the ACD value:
1. Rotate the knob to select the ACD field and press
the knob or the
√ button to activate the field.
When the field is active either rotate the knob, if
necessary, to select "Calc" for a calculated value
or manually enter the ACD value in millimeters
(mm).
2. If you would like the A-Scan to calculate the ACD
press the "Delete" key or the X button to remove
