Enter Patient Data > Handling of Binocular Data

Binocular visual acuity data will be filed in twice, for both eyes separately, since the surgery date of OS and OD may, or may not, be different.

Datagraph-med handles this 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.
