TearLab is now Trukera Medical.

TearLab, founded in 2009, was built upon the recognition of the importance of corneal health to eye care practices. We introduced tear osmolarity testing to eye care with our flagship device, the TearLab Osmolarity System, which has been used to perform over 24 million tests worldwide. In 2022, we announced a corporate name change to Trukera Medical, for our further expansion in corneal health. What began with a focus on osmolarity testing is now a comprehensive corneal health company working to address additional unmet medical needs in eye care.

Our Vision

As Trukera Medical, it is our vision to be the world’s leading and most trusted corneal health company for providers and patients.

Our Portfolio

Trukera Medical offers a portfolio of products designed to meet the needs of eye care providers and their patients.

Are you overlooking a hidden danger? Toxic hyperosmolarity damages corneal cells and drives refractive instability. When hyperosmolarity occurs, salt content can be elevated to toxic levels. Left undiagnosed, it can adversely impact corneal health.1
