The TearLab test is typically appropriate for people experiencing eye discomfort – much like the symptoms described in Dry Eye 101, as well as new contact lens wearers or contact lens wearers having difficulty with their current lenses, patients having refractive and cataract surgery, and anyone who is curious about the current state of their ocular surface health. Ask your Doctor if the TearLab test is appropriate for you. Or click hear to find the Doctor nearest you that has the TearLab technology!
TearLab analyzes the balance of all nutrients, water, antibodies, proteins and all kinds of substances that make up your tear film. Simply put, TearLab measures the salt content which is a measure of the concentration (or osmolarity) of the tears. The higher your osmolarity, the greater the severity of disease, and therefore the need for treatment to stave off chronic dry eye, potential infections and visual disturbances that can occur. Some doctors refer to it as the "thermometer of the eye" as it reflects the inflammation caused by elevated salt content of the tears.
The TearLab Osmolarity test does not hurt, but Dry Eye Disease can! See the signs and symptoms section to know what you can expect from dry eye.
The test takes less than thirty seconds from sample to answer. The tear is collected from the corner of the lower eyelid, not from the eye itself, and takes only 1-2 seconds. You won't even notice it is happening until it's over.
It is important not to take any eye drops or put medication in your eyes at least 2 hours prior to your TearLab osmolarity test. Also the TearLab test should be the first test the doctor performs during your visit, so make sure to let the doctor know you are interested in an osmolarity test when you first check in for your eye care appointment. Do not rub your eyes or do anything to cause your eyes to "tear-up" within 5 minutes prior to the test.
