IOL constants can be imported from the iolCon.org database or entered manually. Imported IOL constants show the date of the import.
Click the add new ( >*) button, to specify own lenses and IOL constants.
Important Note: Datagraph comes with a preloded iolcon.org lens database. No guarantee can be given for its correctness and newer IOL constants may be available after your version of Datagraph-med has been released. It is your own responsibility to double check and update IOL constants regularly.
