Table 1 Data file format example

From: AstigMATIC: an automatic tool for standard astigmatism vector analysis

  Eye Preop Magnitude Preop Axis Postop Magnitude Postop Axis
Data point 1 OD 0.25 007 0 0
Data point 2 OS 0.75 88 −0.25 a
Data point 3 OD −2.00b 90 0 0
Data point N OS −1.00b 180 0 0
  1. Example of the Excel data file format that is read by AstigMATIC to generate the four standard astigmatism vector graphs. Note that the first column and row should not be included in the actual data file. Please use the point decimal notation and not comma. Three data file samples are provided at http://www.lasikmd.com/media/astigmatic/
  2. a This row will automatically be discarded given the missing value
  3. b This row will automatically be converted from -ve cylinder to +ve cylinder format. For example, − 2.00 × 90 will be converted to + 2.00 × 180 and − 1.00 × 180 to + 1.00 × 90
