SM Tube ® is a tube, developed to examine tear function by absorbing tear and is used as an examination and diagnostic method.
It is the latest version of the SM test strip with enhanced handiness and improved design for safety.
Our in vitro experiments to assess tear-absorbing ability confirmed that the device error stayed within ±1.2 mm in the score, which is precise enough to evaluate the human tear volumes.
