Claim 0:
1. An intraocular pressure (IOP) sensing system comprising:
an intraocular pressure sensing implant to be implanted into an eye of a patient for capturing absolute intraocular pressure measurements, such that a proximal end of the intraocular pressure sensing implant is configured to be disposed in an anterior chamber of the eye and a distal end of the intraocular pressure sensing implant is configured to be 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 configured to be disposed in the anterior chamber of the eye; and
an external device for capturing atmospheric pressure measurements,
wherein the intraocular pressure sensing implant comprises a first onboard timekeeping device, wherein the intraocular pressure sensing implant is configured to capture an absolute intraocular pressure measurement in the anterior chamber at an appointed time as indicated by the first onboard timekeeping device, wherein the external device comprises a second timekeeping device, wherein the external device is configured to capture a plurality of atmospheric pressure measurements around an appointed time as indicated by the second timekeeping device, wherein the external device is configured to download absolute intraocular pressure measurements from the intraocular pressure sensing implant, and wherein the external device is configured to calculate 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.
