Antares (Meibography), iLux, and i-PEN.: Dry Eye Diagnosis & Treatment

Happy Girl Fingers Near Eyes 1280x480

Dry eye syndrome, a common and very annoying condition, can be due to a variety of causes. One typical reason for dry eyes is Meibomian Gland Dysfunction (MGD), which leads to a quicker-than-normal evaporation of your tears. Often, the painful symptoms of dry eye then result, such as burning, itching, a gritty sensation and redness.
The Antares (Meibography) offers a precise diagnosis of MGD, and iLux provides effective treatment to bring relief from dry eye irritation. Another valuable diagnostic tool is the i-PEN, which can determine if a patient truly suffers from dry eye, or if the symptoms are caused by a different eye condition.

What is Meibomian Gland Dysfunction (MGD)?

Your Meibomian glands are located in your eyelids, where they secrete an oily fluid that enhances your tear film and slows the evaporation of your tears. This allows the tears to keep your cornea well lubricated for smooth and clear vision.

When the meibomian glands are either blocked or don’t function optimally, the lipid (fatty) layer of your tear film isn’t rich enough to maintain lasting moisture on your eyes. In addition to the rapid evaporation of tears, there is also greater friction between the cornea and eyelids. This is what’s behind the resulting symptoms of eye irritation.

Eye care professionals estimate that approximately 86% of patients diagnosed with dry eye symptoms have a poor quality tear film due to Meibomian Gland Dysfunction. Unfortunately, MGD is chronic and progressive; when left untreated, the symptoms generally worsen.

I-PEN – Osmolarity Assessment

I-MED Pharma’s I-PEN® Osmolarity System is the first quick, easy, and handheld device for optometrists to screen dry eye patients.


  • Quantitative measurement of osmolarity
  • Affordable point-of-care test
  • Quick and simple to use (takes less than 5 seconds per eye)
  • Reproducible, accurate and reliable results
  • Uses Single-Use-Sensors (SUS)

The I-PEN measures tear osmolarity in a fast and effective way, aiding doctors in determining the best treatment for your eyes. Tear osmolarity has been shown to have the best predictive value for diagnosing Dry Eye Disease of any single test. Dr. MacInnis will test both eyes, and will the number of the two tests, to generate Your Osmolarity Number. Your Osmolarity Number gives doctors a meaningful measure of the health and stability of the protective tear film that covers the surface of your eyes. The number generated correlates with the severity of the disease.

Antares Meibographer

The piece does a lot! Mainly for dry eye management, it performs meibography, imaging of the oil glands in your eyelid, and tells us how strong your tears are and how many you produce. It can also perform corneal topography, a measure of the shape of the front of your eye, which is used to diagnose and monitor keratoconus, and help fit specialty contact lenses.

I-LUX Technology

iLux by TearFilm Innovations allows direct visualization of meibomian glands, blockages, and expressed meibum throughout treatment via the magnifying lens, providing a direct view of the treatment area.

The proprietary light-based heat source gently warms the inner and outer lid to a safe therapeutic temperature. Sensors in the disposable iLux Smart Tip monitor inner eyelid temperature continuously during treatment.

One-button control of heating and compression puts treatment in the doctors’ hands, allowing you to choose the location and duration of treatment. iLux measures compression force, which is displayed on the LCD screen.
