The I-PEN^® Tear Osmolarity System
The New Standard for Diagnosing Dry Eye Disease

I-PEN^®, the world’s only portable diagnostic device to detect and measure the tear film osmolarity levels associated with marginal, mild, moderate and severe Dry Eye Disease.

• Quantitative measurement of osmolarity
• Affordable point-of-care test
• Quick and simple to use (Entire test can be done in seconds)
• Reproducible, accurate and reliable results
• Uses Single-Use-Sensors (SUS)

I-PEN^® MEASURES TEAR OSMOLARITY IN SECONDS

The I-PEN^® Osmolarity System is a solid state electronic diagnostic device for the quantitative measurement of osmolarity (concentration of dissolved salts in solution) of human tears in normal and Dry Eye Disease patients..

The I-PEN^® Osmolarity system, used in conjunction with the I-PEN® 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 orbital tissues such as the palpebral conjunctiva. After approximately 2 seconds of contact with the eyelid tissue, the I-PEN^® 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^® Osmolarity Test utilizes an impedance measurement to provide an indirect assessment of osmolarity of the tear film of the eye.

The I-PEN^® is designed for use 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^® is an invaluable asset for monitoring the progress of dry eye treatment therapies. The I-PEN^® is for professional in-vivo diagnostic use only.
