Abstract
Described herein are various devices, systems and methods for measuring the intraocular pressure of an eye using a stress or pressure sensor placed on or in the eye.
Claims20
A device for conforming to the surface contour of an eye, the device comprising:
- a body composed of a biocompatible material and shaped to resemble a contact lens;
- a stress sensor embedded within the body, the stress sensor comprising:
- an annular ring having a central aperture, and a plurality of secondary apertures arranged around the central aperture, the plurality of secondary apertures defining a plurality of struts, the annular ring made of a photoelastic material;
- wherein the shape of the annular ring, the aperture and the plurality of secondary apertures defines a foot print of the annular ring;
- and
- a reflector material layered under the annular ring, the reflector material having substantially the same foot print as the annular ring;
- wherein the struts of the annular ring will flex in response to changes in the surface contour of the eye.

An intraocular lens for measuring an intraocular pressure (IOP) in an eye, the intraocular lens comprising:
- a body composed of a biocompatible elastomeric material, the body being μconfigured to fit inside the eye;
- a first support leg, the support leg extending radially from the body;
- a photoelastic layer having a center aperture and a plurality of secondary apertures arranged in a ring around the center aperture, the secondary apertures defining a plurality of struts, where in the struts operate as a plurality of stress concentration features, the photoelastic layer embedded in the body;
- a reflector layer having a foot print that substantially matches the photoelastic layer, wherein the reflector layer is adjacent to the photoelastic layer;
- a first gas filled cavity adjacent to one of the photoelastic layer and the reflector layer;
- and
- wherein changes in the IOP on the body cause deformation of the photoelastic layer to produce an optical result.

A polarimetric measuring device for reading optical data and producing IOP data, the polarimetric measure device comprising:
- a body;
- a circuit contained within the body, the circuit having a microcontroller, an analyzer and an interface connector;
- a light source in electronic communication with the circuit, the light source having a variable output wherein the variable output is controlled through the circuit;
- and
- a polarizer with a retarding plate, the retardation plate can condition the output of the light source to produce a particular polarization;
- and
- a camera able to capture images in succession from a PECL or a PEIOL device;
- wherein the device may evaluate the images captured by the camera to calculate an IOP reading for an eye.
5 more elements
A process for determining the intraocular pressure of an eye, the process comprising:
- collecting, via a camera, a plurality of images of a PECL or a PEIOL device under a first lighting condition and a second lighting condition;
- registering the plurality of images, via a computer, wherein the registering of the plurality of images eliminates a geometrical drift from the plurality of images;
- filtering, via a computer, the plurality of images;
- locating, via a computer, a plurality of stress concentration areas in the plurality of images, and
- analyzing, via a computer, the stress concentration areas to determine an IOP value.

A system for measuring the intraocular pressure of an eye, the system comprising:
- a deformable sensor suitable for placement on the eye, the stress sensor having a biocompatible body and a photoelastic sensor;
- a polarimetric measuring device, the polarimetric measuring device having a light source and a plurality of polarizing filters, the polarimetric measuring device capable of producing a polarized light;
- and
- a mobile computer device having a camera, the mobile computer device operating a computer program for capturing at least one image, via the camera, wherein the image is produced from the polarized light reflecting off the sensor, the reflecting polarized light passing through at least one polarization filter prior to image capture.
