The Importance of Corneal Health to Surgical Success
Corneal health can significantly impact surgical outcomes for patients.1 Tear hyperosmolarity is toxic to the eye, damaging corneal cells and contributing to refractive instability.2-4
- Tear hyperosmolarity may result in 7x more patients being dissatisfied with their cataract surgery outcomes.5
- Up to 80% of cataract surgery patients may be at risk for ocular surface disease, but they do not always present with symptoms.6
- 1 in 6 cataract patients with hyperosmolarity risk a >1.0 D variation in keratometry measurements. This variability increases the chances of postoperative refractive surprises.4
Tear osmolarity testing is essential for pre-operative planning
The ASCRS recommends pre-operative tear osmolarity testing to identify visually significant ocular surface disease.7

I get asked, “How important is osmolarity testing in modern cataract-refractive surgery?”
And my response is, “How important is quality of vision for your patient outcomes?”
Intraocular light scatter impacts quality of vision8
Hyperosmolarity has been shown to create light scatter equivalent to a grade 2–3 cataract.8,9
Tear hyperosmolarity makes refractive misses and patient dissatisfaction more likely after cataract surgery.5


You’ll be surprised at how much ocular surface risk you were missing before using osmolarity testing and how much better you’ll be able to serve your patients’ needs; a happy patient is a happy surgeon!
ScoutPro is the first and only osmolarity system that is portable, practical, and precise


I am relentless in delivering the highest quality of vision for my patients, and the ScoutPro device provides me the objective data needed for ideal treatment plans.
