I-PEN® VET

THE NEW STANDARD FOR DIAGNOSING DRY EYE DISEASE

I-PEN® VET, the world’s first, hand-held, point-of-care, solid-state electronic diagnostic testing device to detect and indirectly measure the elevated tear film osmolarity levels associated with mild, moderate and severe KCS.

NEW TEAR OSMOLARITY TESTING DEVICE

  • Quantitative measurement of osmolarity
  • Quick and simple point-of-care test
  • Reproducible, accurate and reliable results
  • Uses Single-Use-Sensors (SUSs)

HOW TEAR FILM OSMOLARITY WORKS

The I-PEN® VET Osmolarity System is a solid-state electronic diagnostic device for the quantitative measurement of osmolarity (concentration of dissolved salts in solution) of tears in normal and Keratoconjunctivitis Sicca (KCS) patients.

The I-PEN® VET Osmolarity system, used in conjunction with the I-PEN® VET Osmolarity Single-Use-Sensors (SUS), provides a quick and simple method for determining tear osmolarity of the tissues bathed in the tear film of the papabral conjunctiva. After contact with the eyelid tissue, the I-PEN® Vet will display a quantitative tear osmolarity test result on the liquid crystal display (LCD) in units of mOsms/L. No calculations required. The I-PEN® VET Osmolarity Test utilizes an impedance measurement to provide an indirect assessment of osmolarity of the tear film of the eye.

The I-PEN® VET is used as an in-practice screening device both for patients presenting with dry eye symptoms and for all pre-and post-surgical patients. In addition, the I-PEN® VET is an invaluable asset for monitoring the progress of KCS treatment therapies.

The I-PEN® VET is for professional diagnostic use only.

If you are interested in setting up an in-office demonstration with one of our representatives to learn more about the I-PEN® VET, please feel free to contact us.

I-PEN® VET SINGLE-USE-SENSORS

SKU# 604

The I-PEN® VET Osmolarity Single-Use-Sensor, in conjunction with the I-PEN® VET Osmolarity System, provides a quick and simple method for determining tear osmolarity using impedance measurements of the saline concentration of the extracellular fluid contained in the eyelid tissue. To perform a test, attach a new single-use-sensor into the system reader and touch the tip of the single-use- sensor to the inner tissue of the lower eyelid.

I-PEN® VET SINGLE-USE-SENSORS are sold per box of 50 sensors.

The I-TEAR® TEST

Strip Meniscometry Test for Measuring Tear Volume.

Quantitative Tear Function Test

The I-TEAR® TEST is a quick and easy test to measure the volume of tears produced. The quantitative measurement provides important information on the efficacy of the patient’s lacrymal system as part of a complete KCS diagnosis protocol.

  • Non-invasive
  • Quick, 5 second test
  • No anaesthetic required

How to use:

1. Carefully open the transparent, sterile pouch at either of the ends of the pouch as to not damage the device.

2. Hold in the center of I-TEAR® TEST as indicated in the diagram to the right. Do not touch the tips of the strip containing the blue dye area.

3. Apply the tip of the I-TEAR® TEST of R mark portion on the right eye for 5 seconds to the lateral lower lid tear meniscus without touching the cornea and conjunctiva.

Contact with tear
Avoid touching the cornea

4. Measure the length of the stained tear column, marking by a pen. A reading of 8 and over is normal, anything under 8 is deficient.

5. Repeat the same procedure of L mark portion tip on the left eye.
