The first objective and quantitative test for diagnosing dry eye disease
Proper diagnosis is the first step toward dry eye relief
The TearLab® Osmolarity System is intended to measure the osmolarity of human tears to aid in the diagnosis of dry eye disease in patients suspected of having dry eye disease, in conjunction with other methods of clinical evaluation.
Tear osmolarity is...
Dry eye disease occurs when your eyes do not produce enough tears or produce poor quality tears. That’s why it’s essential you get your tears analyzed by your eye doctor. Only an eye doctor can properly diagnose your problem and treat it appropriately.
Your eye doctor will take a sample of tears from each eye and use the TearLab device to measure osmolarity (the saltiness of your tears). As osmolarity in your tears increase ocular surface cells become damaged. Your doctor will need an amount of tear fluid no larger than the period at the end of this sentence.
