TearLab is the single most accurate and objective test for diagnosing Dry Eye Disease. TearLab generates an Osmolarity number, which provides significant information to your Doctor.
With its objective, quantitative endpoint TearLab Osmolarity correlates to increasing disease severity, and enables your Doctor to monitor your response to treatment. The test is fast, easy, and accurate – requiring only 50-nanoliters of tear for analysis – a sample smaller than the period at the end of this sentence. It is also more patient friendly than older generation tests, as it is not intrusive, and requires no anesthesia.
