When using either of the two map arrays,
pachymetry is performed as follows:
1. Apply the pachymetry probe perpendicular
to the cornea at the location corresponding
to the reverse-highlighted location on the
map array.
2. When the measurement conditions are satis-
factorily set, a beep will indicate that the
instrument is ready to acquire data, follow-
ing which measurements will be automatical-
ly acquired.
3. When 20 measurements have been
acquired, a prolonged beep will indicate
that measurement at this location has been
completed.
Data acquisition can be concluded before 20
values have been obtained by lifting the
probe off the cornea.
4. Remove the probe from the cornea, place
the probe at the next location, which is high-
lighted in reverse on the map array, and
repeat steps 2 and 3.
5. Measure each corneal location as described
above.
6. If you would like to re-test any locations,
touch the location on the screen to reverse-
highlight it and re-acquire measurements.
