Product Information

EyeSense uses the eye as a preferred glucose monitoring site. We are able to eliminate problems associated with other technologies in this field. In the following film the product concept is explained.

The blood glucose is measured in the tissue fluid under the conjunctiva of the eye. This site is particularly well suited due to:

  • The transparency of the conjunctiva which makes optical monitoring ideal
  • The site is normally covered by the eyelid
  • Compared to other body sites, the conjunctiva shows an excellent acceptance of implants. Implanting the sensor is simple and pain free.
  • The conjunctiva has a particularly good blood supply

A biochemical sensor is used to monitor blood glucose. It reacts reversibly to the glucose concentration and correspondingly emits differing fluorescence intensity, correlating to the monitored glucose concentration.

The sensor is placed at the eye rim by an ophthalmologist. The implantation is painless and takes only three minutes. The size, site and material of the mini sensor are specially chosen to firstly avoid a feeling of a “foreign body” in the eye and secondly to leave the functioning areas, essential for sight, untouched. The sensor is not visible and can be worn for up to one year before being replaced. In this time, a small monitoring hand device is used for blood and touch free monitoring. Its emitted light falls on the eye sensor and reads out the returned optical signal sent from the sensor. Once the device is calibrated the results are expressed in the usual blood glucose measuring units.

An added advantage, along with the painlessness, of this completely new measuring technique, is that one can measure as often as wished without additionally incurred costs. A measurement lasts only a few seconds.
