Datagraph comes with a predefined list of Surgery Types which are labeled according to the EUREQUO Database standard. If you are planning to export part of your data later on to the EUREQUO Database, you should try to work with these predefined groups of surgery types. Otherwise you may add or change own groups as needed.
The labels given in the first column will appear as on Datagraph forms and filters as selectable item. The second column (description) contains comments for you to memorize what each label in column stands form. You may enter your own description here. The third column ('belongs to') is defining the type of field mask which Datagraph is going to use. For example 'LASIK' will open fields about flap thickness and flap diameter. 'PRK' on the other hand does not have these fields in the data entry mask.
