Non-contact examination, auto alignment and measurement plus automatic analysis of the endothelium layer make working with the EM-4000 professional and quick (4 sec. for both eyes). Thanks to our auto alignment technology we can assure the reproducibility of the measured area and therefore also the analysed values. The integrated non-contact Pachymetry will be automatically measured with every central examination. The big colour touch screen is used as an operating monitor as well as for displaying all measured values. All commands can be given via touch screen.
