 The TearLab Osmolarity System is the first objective and quantitative test for diagnosing and managing Dry Eye patients.

Provides fast and accurate results in seconds using only 50 nanolitres (nL) of tear film to diagnose Dry Eye Disease

Enables discussion with patients around a number, improving compliance

Incorporating osmolarity into the standard of care gives the best indication of early stage disease

The TearLab Osmolarity System is intended to measure the osmolarity of tears to aid in the diagnosis of dry eye disease, in conjunction with other methods of clinical evaluation. TearLab is for professional 

Hyperosmolarity has been described in the literature as a primary marker of tear film integrity. When the quantity or quality of secreted tears is compromised (known as aqueous deficient or evaporative Dry Eye Disease), increased rates of evaporation lead to a more concentrated tear film (increased osmolarity) that places stress on the corneal epithelium and conjunctiva.
