Tear Osmolarity and Corneal Health

Did you know that tear hyperosmolarity may result in 7x more patients being dissatisfied with their cataract surgery outcomes?1

Up to 80% of cataract surgical patients may be at risk for ocular surface disease, but they don’t always present with symptoms.2

1 in 6 cataract patients with hyperosmolarity risk a >1.0 D variation in keratometry measurements. This variability increases the chances of post-operative refractive surprises.3

The ASCRS recommends pre-operative tear osmolarity testing to identify visually significant ocular disease.4

Intraocular light scatter impacts quality of vision5 


Hyperosmolarity has been shown to create light scatter equivalent to a grade 2–3 cataract.5,6


Tear hyperosmolarity makes refractive misses and patient dissatisfaction more likely after cataract surgery.1
