Accutome A-Scan Plus User’s Guide
To take a patient measurement:
1. Change the necessary measurement settings by
pressing the buttons beneath the measurement
selections. Each of the measurement selections
toggle between one and the other.
2. Set the appropriate Eye Type (the field under OD
or OS) for each eye, Phakic is the default and is
fine for most cataractous eyes. If measuring an
aphakic or pseudo phakic eye, the eye type must
be set accordingly. To set the eye type, select the
eye type field by rotating the knob, activate it and
choose the appropriate type. The type is associ
-
ated with each eye and is retained when the eye
(OD or OS) selected. It is necessary to set the
appropriate eye type for each eye if measuring
each eye.
3. When all measurement settings for the current
Patient are accurate apply the probe to the
Patient’s eye.
4. If you are not using the running mode, press the
foot switch or the Running/Frozen selection. The
Accutome A-Scan Plus will proceed to the next
empty waveform (if available).
5. If you are using the Automatic mode, the Accu-
tome A-Scan Plus will automatically freeze a mea-
surement upon sclera detection, steep retina
detection or upon capturing stable readings. (Auto
Mode settings are defined in the Setup Screen.)
The instrument will emit a high pitched chirp when
you have automatically acquired a measurement.
6. If you are using the Manual mode, and you wish to
capture the current waveform press the foot switch
or the "Running/Frozen" selection.
*Note: The user must review auto measurements for
quality. For more information on taking
measurements refer to "Performing Measurements"
on page 151 of this manual.
