Binocular visual acuity data will be filed twice, for both eyes separately since the surgery date of OS and OD may, or may not, be different.
Datagraph-med handles this as in the following way, depending whether the treatment dates are the same or different for both eyes.
|•||In case OS and OD have been treated on different dates, the 3 month binocular VA of OS may be different from the 3 month VA of OD for example.|
|•||If OS and OD have been treated on the same date, Datagraph will copy the VA data to the other eye during data entry.|
Please note, that graphs showing binocular data, count eyes, not numbers of patients. A patient treated bilaterally on the same day will appear twice on binocular VA graphs for example.
