At Ottwell Eye Care, we use the I-Pen to measure the tear film osmolarity levels associated with marginal, mild, moderate and severe Dry Eye Disease. We use this device for patients who are plugged into our Dry Eye Clinic. The I-Pen takes quantitative measurement of the concentration of dissolved salts in your tears.

It is a quick and simple method for screening for those presenting with dry eye symptoms and also a quantitative way to track the progression of the dry eye therapy designed specifically for you by the optometrist here at Ottewell Eye Care.
