Diagnostic & Specialist - SMT11EU SMTube

“SMTube” For Dry Eye Testing

SMTube is a new improved method for dry eye testing in 5 seconds. The application method is simple, accurate and non-invasive. The tip of the SMTube 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.

Strip Meniscometry Definition

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.
