Mapping Measurement Mode
The
Pachmate 2
’s other
Measurement Mode
option is
Mapping Mode.
In this mode the operator is able to take a
single measurement (not averaged) at various positions on
the cornea. While in Mapping Measurement Mode the
screen will display which eye is being measured, the
mapping position number and the measurement.
The device can also be configured to display an operator
defined measurement bias while in
Mapping Measurement
Mode
. (See section 13.3.2). When biased measurements are
enabled, the screen will display which eye is being
measured, the mapping position number, the actual
measurement and the calculated biased measurement.
With
Mapping Measurement Mode
enabled, the
Pachmate 2
can be programmed to record from
1 to 33 unique measurement positions. The illustration below shows 33 potential measurement
points.
Fig 11.2.1 Potential Mapping Points
Using multiple measurement points allows the user to “map” the thicknesses of the cornea at
various locations; however the operator must keep track of which measurement belongs to each
corneal position. This can be achieved with the help of corneal thickness charts, which are
available upon request from DGH Technology, Inc.

parameters.
