First Design of a Contact Lens for Diagnosis of Dehydration.

ABSTRACT: Dehydration is a serious medical problem for elderly patients and young children. The most widely used diagnostics are measurements of sodium ion (Na+) and potassium ion (K+) in blood serum. Dehydration is difficult to diagnose even by trained health care professionals because the body compensates to maintain the appearance of skin. These measurements required a blood draw because specific tests are generally not available for only Na+ and K+. The blood samples are analyzed by an electrolyte panel (EP) or a basic metabolic panel (BMP). Most hospitals limit EP and BMP to one per day to control costs. More frequent measurements of Na+ and K+ are needed, especially during rehydration. We designed a dehydration contact lens that can provide the Na+ and K+ concentrations as needed or for contin
