New Non-invasive Method for Dry Eye Testing in 5 Seconds

29th April 2019

Do you suffer from dry eyes? Get a quick and accurate diagnosis in 5 seconds with the SM Tube. It’s safe, accurate and non-invasive! This new method is improved in accuracy and duration and replaces the old Schirmer test. The old testing method is time-consuming, invasive and provides false positive results. During the Schirmer test, the paper is immersed into the lower eyelid for 5 minutes, a long duration for a foreign object to be placed into the eye, which stimulates more tears and therefore provides an inaccurate result. SM Tube strip, a disposable testing method which maximises your work-load and offers a comfortable, non-invasive diagnosis for the patient.

SM Tube application method is simple, accurate and non-invasive. The tip of the SM tube strip is immersed into the tear meniscus of the lower eyelid for 5 seconds. During the application, the column of the strip will be stained with blue dye, as it absorbs tears. The length of the blue stained column quantifies the tear meniscus volume, as simple as that.

There is no need for anaesthetic eye drops, and it can be performed without a slit lamp by nurses and healthcare assistants, or with a slit lamp by an ophthalmologist or optometrist. In both cases, the application method is the same.

Strip Meniscometry is a term of a methodology for the tear volume evaluation, used in the diagnosis of dry eye disease. The material and structure of the strip are designed with careful consideration for ocular safety. Should the tip of the strip touch the cornea or conjunctiva no damage will occur to the patient eye.

SM Tube is a thin strip with a central ditch filled with the absorber. The scale is printed on both sides of the absorber to measure the tear meniscus volume. Each SM Tube is packaged individually in a sterile pouch.
