What is TearLab?

TearLab is the single most accurate and objective test for diagnosing dry eye disease. This test generates an osmolarity number that provides significant information to monitor your response to treatment. The test is fast, easy, and accurate, requiring only 50-nanoliters of tear for analysis — a sample that is smaller than the period at the end of this sentence. TearLab is also more patient-friendly than older generation tests, as it’s not intrusive and requires no anesthesia.

Why are Healthy Tears Important?

Healthy tears form a crucial film over the ocular surface of your eye — and the health of these tears directly affects the health of the ocular surface. A healthy ocular surface is vital for stable vision. 

How TearLab Helps Dry Eye

Dry eye is one of the most under-diagnosed ocular diseases, and yet it’s the most common reason why patients go see their eyecare professional. Dry eye occurs when eyes do not produce the right quantity or quality of tears. Your eyes need a constant layer of tears to maintain and protect the ocular surface. In dry eye, underlying changes to the health of the tear-producing glands can result in a change in the quantity and quality of the tears you make. This can lead to damage of the eye’s surface, which in turn can lead to the symptoms of dry eye. TearLab can help Dr. Kelly monitor and treat dry eye.

What’s Your Number?

The osmolarity of your tear film — determined by the TearLab osmolarity system — is a measurement of the salt content in your tears. Osmolarity is the accepted gold standard for objectively diagnosing dry eye disease. Essentially, osmolarity gives doctors a meaningful measure of the health and stability of the protective tear film that covers the surface of the eye. Dr. Kelly will test both of your eyes, and will then take the highest result of the two eyes to determine your “osmolarity number”. Once this number has been generated, we can determine whether you have dry eye disease — and if so, whether you fall into the mild, moderate, or severe category. This will help Dr. Kelly create an appropriate treatment plan to bring your ocular surface and tear film back to good health.
