    Fascinating. It does point up the fact that no one is blamed or shamed for myopia or presbyopia. If your eyes don’t function as well as other people’s eyes, no one clucks their tongue at you and tells you to work harder to read the eye chart or blames it on what you’ve been looking at. If only people felt the same way about the pancreas.

    Like Dr. Ginsberg, I question the application of such a tool. So many patients aren’t willing to inject multiple times a day or check BG more than a few times a week; a weekly contact lens that only serves as emergency back-up seems unlikely to appeal to this population.
    Moreover, if you’re not looking at the lens, how would you know it is delivering insulin? It would act as very small bandaid over a big underlying problem…so insurance companies may not save that much money in the long-run if these patients aren’t actively paying attention to the contact.
    As far as it being good for small children with T1D…eeesh, that idea is scary. I wouldn’t want any of my pediatric patients getting up to 25 units of insulin at a time — or ANY insulin — without the mechanical OK from a knowing adult.
    Negativity aside, I AM supportive of research in this arena. You never know what other applications may come of it.

    Interesting, probably fundable exploratory research for sure [can you say SBIR from NIH], but the regulatory quagmire and recalcitrant population for which it is aimed does not seem to make this appear to be a particularly likely commercial device. One wonders if this approach will be ultimately aimed for a different drug deliver application?.

    When the contact lens is on the eye of an individual it will contain insulin in a stable state. However, after the glucose concentration in the eye reaches a certain level (which is indicative of blood glucose concentration), the polymer changes conformation and insulin is released into the eye. The insulin will be absorbed by the conjunctiva and nasal cavity and will subsequently lower systemic blood glucose levels. This contact lens is meant as a safety device to keep patients from having a DKA episode; not as a replacement therapy. Disclaimer: We realize that we will have to increase the insulin bolus dose for patients in severe hyperglycemic states, but this is just a simple example.
