Glucose monitoring with high-tech contact lenses

contact lens resized 150×150Researchers at the University of Akron in Ohio are developing contact lenses that may make those finger sticks a thing of the past. Blood glucose isn’t the only thing to vary during the day as glucose concentrations change. Along with blood also urine and tear glucose levels change to mimic or match that of the blood. Dr. Jun Hu has coated a contact lens with a chemical that reacts to glucose in tears similar to pH paper changes. The coatings causes the lens to change color. Patients wear the color changing lens in only one eye.

Measurements taken with a cell phone app allows the color difference between the two eyes to produce a tear (and hence blood) glucose calibration. No special light is needed; all patients need is a smartphone with a camera.

Patients vision is not affected by the tinting process. These lenses are in use but only in the testing phases. Expect to see them commercially in 3-5 years.

Bandage contact lenses for healing, pain and corneal protection

Contact lenses have been used for the following:

  • recurrent corneal erosion
  • corneal perforation or laceration
  • bullous keratopathy
  • epithelial defects due to trauma or chemical burn
  • post penetrating keratoplasty

Amazing that something that weights about the same as a drop of water, is about 100 microns thick and is transparent can be a powerful a tool in treating eye pain and healing.

Hello patients

This is our first weekly blog/post.

On it we’ll try and pick up at least one case a week that for us was interesting. As well share stories of our lives or things that have touched the lives of the practice. Our staff all share a passion for eye care and I hope this site gives you a sense of our mission and our passion.

I was going to share a story or two on this first blog but instead I will post our mission statement. We developed it in 1983 and it has stood the test of time. We’ve shortened our mission to Preserve and Optimize but the essence of our mission has not changed.

Our Mission

Our mission is to provide excellence in eye care services and products. We, the doctors and staff pledge to make our patients’ vision and eye health needs our priority.

As a team of dedicated professionals, we pledge to adhere to the highest sandards in everything we do while maintaining a friendly, empathetic practice environment.

In fulfilling this mission, we desire to make positive changes in the lives of our patients. Our goal is to listen carefully to your concerns and to make our best attempt to address them.

—Dr. Evans
