How to define "sAngle" in the stribute setting please?

[Forrest]

I would like to get the sagittal height of cornea for a specified chord length. According to the attribute command in Medmont studio for e300, the formula "CornealHeight" needs me to define the "sAngle" and "sHalfChord".

Can anyone tell me how to define them please?

Best regards,
Forrest

You can just substitute the words 'sAngle' and 'sHalfChord' with the angle and chord which you are interested in. The angle is defined as 0 at the 3 o'clock position increasing anti-clockwise. The sHalfChord is the distance from the center optical axis in mm. The overlaid grid lines are in 1 mm increments or you could click on the point of interest and use the readout values in the bottom right hand corner (Dis and Ang).
