The study is intended to evaluate a non-invasive method of glucose measurement in diabetics. The medical device that is evaluated consists on a sensor-insert which is placed under the conjunctiva of the eye of diabetic patients and a photometer. The goal is to prove that the sensor signal correlates with the blood glucose of the patients determined by standard laboratory blood glucose measurement.

Insert is placed under the conjunctiva. During measurement sessions photometer will be placed in front of the eye in which the insert is located to perform the fluorescence measuring.
An improved insert is placed under the conjunctiva. During measurement sessions photometer will be placed in front of the eye in which the insert is located to perform the fluorescence measuring.
Insert is placed under the conjunctiva. During measurement sessions photometer version 2 will be placed in front of the eye in which the insert is located to perform the fluorescence measuring.

After comparing Photometer Version 1 and Version 2 the better one of them will be used for measurements in Cohort 4. A new insert will be implanted under the conjunctiva.
The insert version with the best results will be implanted. The photometer that was used in Cohort 4 will be taken again for fluorescence measurements.
