WF Ref data-set
Initially displays the results of the wavefront analysis. As the subjective refraction
progresses, the values are modified based on the patient's responses.
During the subjective refraction, when this eye is being tested, the data set in this
column is called #2, as it is for the right eye in the illustration above.
Note: The actual results of the wavefront analysis are not modified during the
subjective refraction. They can be seen in the Exam File screen.
8
LM data-set
If lens meter data was entered before measurement then the data will be displayed
on this column . As the subjective refraction will be done around the lm and WF, if
there is no LM data then wf data will be also shown on this column ,the settings are
modified based on the patient's responses.
During the subjective refraction, when this eye is being tested, the data set in this
column is called #1, as it is for the right eye in the illustration above.
Note: The LM data-set settings are not modified during the subjective refraction.
They can be seen in the Exam File screen.

Manual Refraction
Manual Refraction is available just from Quick Pro Mode, you have direct control over all of the
system's features by clicking on the refraction tabs. The right side of the Refraction screen
contains a chart display and chart controls, and the left side of the screen displays the
refraction values, which you can modify as required. As you proceed, the phoropter
automatically resets the lenses to match the refraction values you enter.
