"angErr" function. The Angle of Error between the SIA and the TIA

The Angle of Error is the difference of angle between the SIA and the TIA and represents the rotation of the Surgically Induced Astigmatism in reference to the Target Induced Astigmatism.

This function calculates the standardized Graph H detailed in the Journal of Refractive Surgery(1) from a single vector that contains the Angle of Error from the sample.

Example:

  • angErr(AE,1,'en')

Below you have the help of the function. For more information about "refractiveAnalysis" Toolbox please Contact the author.

%   Computes the Angle of Error defined as the difference of angle between
