GUIDE OF USE
Do the patient have a seat comfortably using the chin holder and support for the front: in this way the

The IDRA must be kept as close as possible to the eye without touching. Closer is the device to the eye,
broader is the area lighted by the instrument. The light reflected from the tear film can be observed as a
white circular area that almost completely covers the cornea.
The observer system is placed to allow analysis through the central hole of the IDRA, through the tablet
screen.
The exams done with white leds require the use of the main cone to prevent all possible external and
internal reflections. The exams of Meibomian glands, B.U.T. and Demodex require to remove this cone as
follows
1) Turn around the inserted cone
2) Then, remove the cone to detach from the magnets
Functional Features
The device IDRA is the result of a long period of research done with the most accredited professionals,
to give the highest combination between technical innovation, quality and design. As already mentioned,
