Claim of US Patent No. 10,987,033

1. A system for monitoring a glucose concentration in aqueous humor, the system comprising:an implantable device configured to be surgically implanted in an eye and having a first end and a second end, the implantable device defining a lumen extending through the implantable device configured to transmit the aqueous humor from the first end positioned in an interior portion of the eye to an exterior portion of the second end positioned exterior of the eye;
a light source configured to direct polarized light through the aqueous humor on the exterior portion of the second end; and
a polarimeter configured for:
receiving reflected polarized light that reflects from the exterior portion of the second end after passing through the aqueous humor on the exterior portion of the second end;
detecting a polarity of the reflected polarized light; and
determining the glucose concentration in the aqueous humor as a function of the detected polarity of the reflected polarized light.
