Dry Eye Evaluation

The best way to get relief from your dry eye symptoms is by having a professional assess your eye health. At Fisher-Swale-Nicholson Eye Center, we utilize two methods to get to the root cause of your symptoms so we can recommend effective treatments:

  • TearLab Osmolarity System®
  • OCULUS Keratograph®

These tests assess the health of your tear film. Tears form a film over your eyes, important to keeping your eyes lubricated, hydrated and healthy. If you have poor quality tears or your eyes are not producing enough tears, this will lead to eye irritations and fluctuating vision.

TearLab Osmolarity System®

This evaluation is done to measure the saltiness of your tears (osmolarity). If your tears have excess salt content, this could be damaging the surface cells of your eyes. Only a tiny sample of tear fluid is needed to diagnose your tear fluid. This is a very quick and painless process that is done right in our office. Your tears will be graded on an osmolarity scale: normal, mild, moderate or severe.

OCULUS Keratograph®

This evaluation is done to measure the quality and quantity of your tear film. The process takes less than 30 seconds and only requires you to look into a machine – we never have to touch your eye for this evaluation. The Keratograph will assess the health of your eyelid glands (meibomian glands) and the lipid (oily) layer of your tears.
