We have the accumulated experience and technical development over 30 years on composite processing of various adhesive materials. Based on the application of those knowledge, we now come out with a medical device devoted to a simple, swift and non-invasive lacrimal function tests: "Strip Meniscometry Tube" (SMTube).


The SMTube enables very quick (5 seconds) examination with minimized pain in eyes. Dry eye syndrome is a considerable ocular disorder causing a decreased visual function and a visual discomfort, which may eventually lead to keratic and conjunctival diseases. 


< How to Use > 


①Immerse a tip of the SMTube gently
into a tear meniscus for 5s.


②The SMTube scores the tear amount
through its colored length within the tube.
