>Our clinical work on the glucose-sensing lens demonstrated that there was insufficient consistency in our measurements of the correlation between tear glucose and blood glucose concentrations to support the requirements of a medical device. In part, this was associated with the challenges of obtaining reliable tear glucose readings in the complex on-eye environment. For example, we found that interference from biomolecules in tears resulted in challenges in obtaining accurate glucose readings from the small quantities of glucose in the tear film. In addition, our clinical studies have demonstrated challenges in achieving the steady state conditions necessary for reliable tear glucose readings. Why wasn't this clinical work done prior to any work on "smart lenses"? This is like Theranos trying to build all this equipment to support fingerprick blood tests only to find out that venous blood is superior for a lot of things that you want to measure.
