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 follows depending whether treatment dates are same or different for OS and OD.
|•||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 graph showing binocular data count eyes, not number of patients. A patient treated bilateraly on the same day will appear as two data points of binocular VA data for example.
