The DR-1α Kowa is a new diagnostic device for dry eyes. This device uses the principle of the interferometry for the purpose of the tear film-analysis. So you can quickly and easily observe and record the color change on the surface of the lipid film during the spread of tears after blinking.
You can therefore observe the Break-Up Time (NIBUT - non invasive break up time) without touching the eye surface. In addition, you can also analyze the dynamics of the tear film while the patient wears contact lenses. The ability to save the captured images to a computer gives you finally the unique opportunity to compare images before and after treatment and thus to perceive what is the degree of improvement.
