INTRAOCULAR PRESSURE SENSING DEVICES AND ASSOCIATED SYSTEMS AND METHODS

摘要

The present technology relates generally to intraocular pressure (“IOP”) monitoring systems and associated devices and methods. In some embodiments, an intraocular pressure monitoring system configured in accordance with the technology comprises an implantable intraocular assembly and an external unit configured to transmit power to and receive data from the intraocular assembly. The intraocular assembly can include an IOP sensing device embedded within a flexible, expandable annular member. The IOP sensing device can include an antenna, a pressure sensor, and a microelectronic device encapsulated by an elastomer.

1. An intraocular pressure (“IOP”) monitoring system, the IOP system comprising:
an implantable intraocular assembly configured to be positioned within a capsular bag of
a human eye, the assembly including—an annular member;an IOP sensing device embedded within the annular member, the IOP sensing device comprising a microelectronic device, a pressure sensor configured to measure an intraocular pressure, and a first antenna configured to receive a radiofrequency (“RF”) signal; and an external unit configured to be positioned external of the patient, the external unit including—
a second antenna configured to transmit an RF signal to the first antenna to charge the IOP sensing device; andmemory and processing circuitry configured to convert a pressure measurement into a frequency measurement, wherein the pressure measurement is measured by the pressure sensor.
