Auto Interferometry The IDRA automatically evaluates the quantity and quality of the lipid component on the tear film. Nibut The stability of the mucin layer and the whole tear film is assessed through the study of non-invasive break up time (NIBUT), by using the Placido cone projected onto the cornea. Tear Meniscus Thickness The tear meniscus can be examined considering its height, regularity and shape. Blink Evaluation It has been established that efficient blinking plays an important role in ocular surface health induding during contact lens wear and that it improves contact lens performance and comfort. AUTOMATED LIPID LAYER ANALYSIS The IDRA software analyses lipid layer thickness and allows to understand the functionality of Meibomian Glands. It is possible to carry out a follow up after MG treatment detecting an Increase in secretion. A typical blink pattern can be observed as approximately one blink every five seconds, ie 11 blinks per minute. Incomplète blink can often be observed in contact lens wearers, and frequent blink may be a resuit of an attempt to maintain a relatively thin lipid layer. The software automatically detects the coloured lipids on the patient's eye and determines lipid layer thickness (LLT). In a few seconds it is possible to get automatically relevant data to understand functionality of Meibomian Glands.
