Abstract
Objective:
The purpose of the present study was to determine the effectiveness of a fluorescent contact lens glucose sensor in monitoring glucose in patients with diabetes.
Methods:
Under an institutional review board-approved protocol, five fasting patients with type II diabetes were given a challenge consisting of 75 mL of Sustacal (Thomson Micromedex, Greenwood, CO) by mouth. Contact lens fluorescence and venous blood glucose were measured over a 3-h period.
Results:
Contact lens fluorescence appeared to track blood glucose well. The fluorescent dailywear disposable contact lenses were comfortable and were tolerated well, even in patients who had not previously worn contact lenses.
Conclusion:
The contact lens glucose sensor shows promise as a home glucose monitor.
