Start the measurement using pushbutton on the joystick.
Note:
Before the measurement, tell the patient to look at the yellow
fixation light and not into the lateral slit which is flickering during
the measurement.
After engaging the measurement move the instrument to the side
for patient comfort. The instrument calculates the ACD values,
which takes approximately 15 seconds.
Explanation: Anterior chamber depth on the IOLMaster means the
distance between the anterior vertex of the cornea and the anterior
vertex of the eye lens. Hence, the displayed distance includes the
thickness of the cornea.
Calculation of the anterior chamber depth requires the input of the
corneal radius. If you performed a keratometer measurement before
the measurement of the anterior chamber depth, the system will
automatically use the measured radius for the calculation.
If the corneal curvature could not be measured with the IOLMaster, a
window will appear requesting you to type in the radius (if the cornea
is astigmatic, the values of both principal meridians).
Enter a value between 4.0 and 13.0 mm (use decimal point). Proceed
with
<OK>
or <
Enter
> key.
If you have choosen the display
Refractive Index",
enter a number
between 26 and 80 please. When you enter the refractive power,
make sure that on the IOLMaster the same keratometer refractive
index is set as on the keratometer that was used for the
measurement (-->
p. 18
).
In the display field beside the video image five ACD results are listed
along with their average.
In the message bar, a blue status bar will appear. In the display field
beside the video image, five ACD results are listed together with the
calculated mean value.
The anterior chamber depth measurement may be repeated if desired.
If you take additional measurements of anterior chamber depth, the
previously measured values will be overwritten.
To restore the last (just overwritten) results, press shortcut key <

Note:
The "UNDO" function itself cannot be undone!
