With the function "Open Patient" an already saved patient is loaded into the program. Navigate to the directory you saved your patient's data to and click on the desired patient file (.eye- or .sye-file).

 

Confirm the dialog with the "Open" or "Öffnen" button to load the file into the program. If you hit the "Cancel" or "Abbrechen" button, no patient is loaded and the data used before you called the "Open Patient" function is retained unchanged.
