Instruments: Care suite for dry eye

Bill Harvey looks at a complete dry eye package from Essilor Instruments

Back in pre-pandemic times, I had the opportunity to try out the IDRA system (figure 1), an adapted camera system that is mounted on a slit-lamp base and allows easy, accurate and repeatable analysis of the tears and ocular surface. Tests such as meibography (figure 2), non-invasive tear break-up time (figure 3), tear volume prism height measurement (figure 4) and blink rate and patency analysis (figure 4), and interferometry of the lipid layer (figure 5) were all easy to perform. Best of all, the results could then be combined (figure 6) and presented as part of a management plan to address a patient’s dry eye disease. See Optician 21.12.18 for my review.
