An objective and quantitative point-of-care diagnostic test that provides precise and predictive information.
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.
A STUDY PRESENTED AT AAO†Found:
All patients with contact lens discomfort and less than 8 hours of daily wear time had abnormal osmolarity.
These patients were put on a treatment to reduce osmolarity levels, resulting in an average increase of 4.6 hours in daily contact lens wear time.
Osmolarity: What the numbers reveal
Tear osmolarity is informative when the results are abnormal or normal.
Abnormal Osmolarity is defined by:
An elevated reading, >300 mOsm/L, indicating loss of homeostasis.
OR, When the inter-eye difference is >8 mOsm/L, indicating instability of the tear film.
Osmolarity is an important biomarker of ocular surface health
