RMS
RMS is displayed in red when corneal or RMS equivalent sphere is greater than
>4D
or when corneal HOA RMS equivalent sphere is greater than 0.5D in either eye.
5 KPI
KPI result is displayed in red when its value is higher than the normal population
6
IOPc
The IOPc value is displayed in red when the inter-ocular pressure is above
21mHg, irideo angles are displayed.
7 Pachymetry
Pachymetry is displayed in red and irideo anges are displayed when the central
corneal thickness is below 400µm or higher than the 700µm.

Ocular
The WF sub-tab displays wavefront maps of the measured ocular aberrations of one or both
eyes.
Display options allow you to view results for photopic and mesopic conditions, to view maps of
both eyes at once or of each eye individually, to isolate lower- and higher-order aberrations, to
change the step and central value of a map, and to superimpose guidelines of various types
onto the maps.
Aberrations values and maps can be shown in OPD (optical Path Difference) mode or in WFE
(WaveFront Error) mode, as defined in the settings screen (See the
General subtab under
the results tab of the settings screen )
The Optical Path Difference (OPD) is defined as the difference between the aberrated and
the ideal unaberrated wavefronts. The OPD is positive if the aberrated wavefront leads the ideal
