Abstract
Intraocular pressure sensing devices and methods of use. The intraocular pressure sensing devices may include one or more calibration sensors that are adapted to sense fibrotic growth over the implant post-implantation. Methods can take into account the amount of fibrosis over the implant, and its effect on IOP, when calculating the subject's IOP. Additionally, methods herein can calculate IOP while factoring in blink-induced variation in IOP.

1-17. (canceled)
A method of creating a personalized correlation between blinking and intraocular pressure changes, the method comprising:
- in a patient that has been implanted with an intraocular pressure sensing device comprising an intraocular pressure sensor, calculating measured intraocular pressure over a period of time based on an output from the intraocular pressure sensor;
- calculating a blink-induced variation in intraocular pressure for the patient, the blink induced variation caused by blinking;
- and
- storing the blink-induced variation in intraocular pressure for the patient in a storage device.
A computer executable method, the method comprising:
- receiving as input information that is indicative of an output from an intraocular pressure sensor;
- and
- calculating an intraocular pressure sensor for a patient, while factoring in a personalized blink-induced variation in intraocular pressure of the patient.
