Datagraph-med© Help 5.30

There are many ways for quality control in cataract and refractive surgery. A careful follow up on treated patients, well documented in patient files is the first step and usually done in every refractive clinic. Commonly available software, such as MS-Excel, may help to get a better overview on outcomes of your surgery. One may even go a step further and incorporated a more appropriate database software, such as MySQL, FileMaker, FoxPro or MS Access, to enter and analyze data. This already requires some programming skills and experience in order to make it work. The amount of time and cost, which needs to be spend for an own, clinic specific database application, is substantial.

Its clearly the better choice to use commercially available outcomes analysis software, such as Datagraph-med© . Started in 1998 as 'engineers tool to refine excimer laser nomograms', it became one of the most popular software tools for cataract and refractive surgery outcomes analysis. Now, beginning of 2016, Datagraph-med is used in more then 50 countries and hundreds of refractive clinics around the world. The initial use for laser refractive to refractive surgery has been extended to cataract surgery outcomes and beyond.

Datagraph-med uses the relational database software from Microsoft, called 'Access'. 'Relational' means, that data is stored in several tables which are linked to each other, using certain 'index fields'. These tables keep general patient data sperate from follow up data or zernike wavefront data for example. The advantage of a relational database system is, that data is stored more compact than in an excel spread sheet alone. Follow up data fields are added to your database only at the moment data is entered. The relational database structure also helps to avoid collecting data which is redundant.

The main feature of Datagraph-med however is, the instant generation of 'presentation graphs', which are always updated as soon as new data is being entered. Fully integrated in MS Office (currently all 32 bit versions versions of MS Office 2010, Office 2013 and 2016 are supported), it becomes possible to prepare lectures and PowerPoint presentations 'on the fly' (e.g. on the way to the next congress!).

An other important feature of Datagraph-med, is the separation of the actual data file (called 'back end') from the database application software (called 'front end') itself. By doing this, one can have different database files for different patient groups and backup or transfer patient data easily. The data file can be stored on a server and accessed from several users at the same time in a local network environment.
