COMPlog’s vision measurement and test chart functions have been rigorously developed into an easy to use system.

COMPlog uses two monitors connected to one PC. The control monitor is operated by the Medical Professional or Technician running the test and the patient reads from the secondary monitor.

In addition to acuity measurement COMPlog provides full refraction and orthoptic test support. As well as automating the acuity measurement process COMPlog allows acuities ranging from 1/60 to 6/3 to be measured from one testing distance.

COMPlog is fully integrated with the Medisoft EMR.  Integration with OpenEyes is under development.  Other integrations can be easily developed using various communications including HL7 and the SQL database.
