Corneal topography methods

1. A method of producing and disseminating corneal topography information, comprising:

generating an illumination pattern to be reflected off a cornea of a subject;

capturing, at an image sensor, an image of the reflected illumination pattern;

adjusting, using an optical configuration, the image of the reflected illumination pattern, and adjusting an optical path length to decrease the optical path length between the cornea of the subject and the image sensor, wherein the optical path length comprises a mirror, a first portion of the optical path length extending from the cornea to the mirror, a second portion of the optical path length extending from the mirror to the image sensor;

communicating the captured image of the reflected illumination pattern to a topography processor;

processing, at the topography processor, the captured image to generate one or more topography map images and one or more topography data files; and

communicating the captured image, the one or more topography data files and/or the one or more topography map images to a mobile communication device;

wherein light from the reflected illumination pattern travels along the first portion of the optical path length to the mirror, and light from the reflected illumination pattern travels through one or more lens assemblies in the second portion of the optical path length to the image sensor; and

wherein the one or more lens assemblies are positioned along the second portion of the optical axis to image the reflected illumination pattern at a magnification so as to fit a size of the image sensor, and wherein the magnification is between 0.25 to 0.75.

2. A method of producing and disseminating corneal topography information, comprising:

generating an illumination pattern to be reflected off a cornea of a subject;

capturing, at an image sensor, an image of the reflected illumination pattern;

adjusting, using an optical configuration, the image of the reflected illumination pattern, and adjusting an optical path length to decrease the optical path length between the cornea of the subject and the image sensor;

communicating the captured image of the reflected illumination pattern to a topography processor;

processing, at the topography processor, the captured image to generate one or more topography map images and one or more topography data files;

communicating the captured image, the one or more topography data files and/or the one or more topography map images to a mobile communication device; and

determining, utilizing two or more proximity sensors, whether a left eye or a right eye of the subject is being examined by detecting a cheek or a nose of the subject.

3. The method of claim 1 , further comprising communicating the captured image of the reflected illumination pattern from the mobile communication device to the cloud-based computing device.

4. The method of claim 2 , further comprising: communicating commands or instructions to the image sensor to control or adjust a size, a resolution or a frame rate of the captured image that the image sensor communicates to the topography processor.

5. The method of claim 1 , further comprising presenting the one or more topography map images on a mobile communication device display.

6. The method of claim 1 , further comprising communicating the one or more topography data files and/or the captured image of the reflected illumination pattern to a cloud-based server or remote computing device.

7. The method of claim 1 , wherein the illumination pattern is a ring pattern and wherein the one or more topography data files include ring edge location measurements, calibration data, patient identifier data or x-y-z offset data.

8. The method of claim 6 , wherein the one or more topography data files and/or the captured image of the reflected illumination pattern are communicated to the cloud-based server or the remote computing device via a wireless communication transceiver operating according to a wireless communication protocol.

9. The method of claim 2 , wherein the optical path length extends along an imaging axis to the image sensor.

10. The method of claim 1 , wherein the captured image is viewed on the mobile communication device and wherein a surface of the mobile communication device is tilted with respect to a vertical axis to provide enhanced viewing of the reflected illumination pattern image by an examiner.

11. The method of claim 2 , further comprising communicating the captured image of the reflected illumination pattern from the mobile communication device to the cloud-based computing device.

12. The method of claim 2 , further comprising presenting the one or more topography map images on a mobile communication device display.

13. The method of claim 2 , further comprising communicating the one or more topography data files and/or the captured image of the reflected illumination pattern to a cloud-based server or remote computing device.

14. The method of claim 2 , wherein the illumination pattern is a ring pattern and wherein the one or more topography data files include ring edge location measurements, calibration data, patient identifier data or x-y-z offset data.

15. The method of claim 2 , wherein the optical path length comprises a mirror, a first portion of the optical path length extending from the eye to the mirror, a second portion of the optical path length extending from the mirror to the image sensor.

16. The method of claim 15 , wherein light from the reflected illumination pattern travels along the first portion of the optical path length to the mirror, and light from the reflected illumination pattern travels through one or more lens assemblies in the second portion of the optical path length to the image sensor.

17. The method of claim 2 , wherein the captured image is viewed on the mobile communication device and wherein a surface of the mobile communication device is tilted with respect to a vertical axis to provide enhanced viewing of the reflected illumination pattern image by an examiner.
