Claim 14:
15. An intraocular pressure (IOP) sensing method comprising:
capturing an absolute intraocular pressure measurement from an intraocular pressure sensing implant implanted in an eye of a patient, wherein a proximal end of the intraocular pressure sensing implant is disposed in an anterior chamber of the eye and a distal end of the intraocular pressure sensing implant is disposed in a suprachoroidal space of the eye between a choroid of the eye and a sclera of the eye, wherein the intraocular pressure sensing implant comprises a sensing module disposed in the anterior chamber of the eye, and wherein the intraocular sensing implant further comprises a first onboard timekeeping device, the absolute intraocular pressure measurement having been captured in the anterior chamber at an appointed time as indicated by the first onboard timekeeping device;
capturing a plurality of atmospheric pressure measurements from an external device outside of the eye, wherein the external device comprises a second timekeeping device, the plurality of atmospheric pressure measurement having been captured around an appointed time as indicated by the second timekeeping device;
downloading, via the external device, absolute intraocular pressure measurements from the intraocular pressure sensing implant; and
calculating a gauge IOP value avoiding inaccuracies due to an offset between the appointed time as indicated by the first onboard timekeeping device and the appointed time as indicated by the second timekeeping device.
