SMTube is a general medical device developed for tear assessment in dry eye clinical practice. Simply placing it in contact with the tear meniscus of the lower eyelid for 5 seconds per eye allows tears to be collected in a simple, rapid, and minimally invasive way.
In recent years, tear fluid biomarker research, which analyzes proteins and other components contained in tears, has been attracting attention. Building on these features of SMTube, we are applying it to tear collection for tear fluid biomarker research.

* In Japan, SMTube is a general medical device notified for the intended use “tear secretion function test (tear meniscus volume measurement)”. Its application to biomarker analysis is at the research stage (Research Use Only) and does not claim to diagnose any disease.
