About Dry Eye Disease

Tears are vital to your eyes, and if natural tears are not able to provide adequate lubrication to the eyes, it can cause serious issues, including dry eye disease. This is also known as an inadequacy or imbalance of tears. These inadequacies or imbalances are often caused by blockages in the meibomian glands in the eyelids. These glands are what produce the top layer of the tear film and are the base of long-term eye comfort and health. When the tear film is not allowed to fully form because of the blocked glands, more dry eye symptoms start to form and can lead to dry eye disease.

I-PEN® Tear Osmolarity System

Osmolarity testing is the most objective way of diagnosing and measuring dry eye disease, and it is the single best marker of disease severity. I-MED Pharma is pleased to offer you the I-PEN®, which, used in conjunction with the single-use-sensors, is the only diagnostic testing device to detect and measure the elevated tear film osmolarity levels associated with marginal, mild, moderate, and severe dry eye disease.

This is a solid state electronic diagnostic device that provides you with quantitative measurements of osmolarity (the concentration of dissolved salts in solution) of human tears. This is able to compare the tears to normal conditions and can easily show you if your patients are suffering from dry eye disease.

The I-PEN® can be used in conjunction with our Single-Use Sensors (SUS) too. This provides accurate and reliable results in each test. The SUS are individually wrapped for patient use and very affordable, coming with 50 sensors in each box.


An important step in diagnosing aqueous deficient dry eye syndrome is getting a quantitative tear function test. That is where the SMTube® comes in. It has a strip meniscometry to measure tear volume in your patients. This is a non-invasive test where tear volume is quantified within five seconds, with no anaesthetic required. Replace the Schirmer’s Test in your practice and go from five minutes to five seconds with accurate and reliable results!

To use it, you simply open the sterile pouch, apply the tip of the tube to the eye as directed, and measure the length of the stained tear column. Once you do this with both eyes, you will be able to get quick, accurate results that will help you to diagnose dry eye syndrome. In some cases, the results will be clear, and in others you may still need to perform a test with the I-PEN® to ensure you are getting the most accurate readings for your patients. However, with the SMTube® you will be able to see the results faster than normal and you may be able to submit a diagnosis and prescribe treatment easily so that your patients can stop having issues with dry eyes.


This revolutionary dry eye diagnostic and analyzer is designed to create a new standard for dry eye analysis with two completely new patented examinations: Ocular Surface Inflammatory Evaluation (OSIE®) and Tear Film Stability Evaluation (TFSE®). As well as these two incredible evaluations, the tearcheck performs the following exams:

  • Eye redness check
  • Meibography IR
  • Tear meniscus
  • Demodex
  • OSDI questionnaire
  • Abortive blinking test

OSIE® is a test that shows the increased risk of inflammation in the eye, shows the exact dimensions and score of the dryness in all areas of the eye, and it is the new standard tool for eye surgeons and lens-opticians.

TFSE® shows the micro-movements of the tear film, offers a quick (10-second) evaluation, and gives the user an exact score of dryness.

You will also be able to check the non-invasive breakup time (NIBUT), which shows the geography and timing of appearance of the rupture zones of the surface of the tear film.

With all of these tests combined into this powerful package, you can see everything related to the tear film and dry eyes quickly so you are able to assess the severity of your patient’s dry eye disease and diagnose it. The more quickly you are able to provide this info, the sooner they will be able to enjoy relief!
