  • Patent number: 11890054
    Abstract: A mobile communication device-based corneal topography system includes an illumination system, a mobile communication device and a corneal topography optical housing. The illumination system is configured to generate an illumination pattern and to generate reflections of the illumination pattern off a cornea of a subject, wherein the illumination system is aligned along an axis of centers of the illumination pattern. The mobile communication device includes an image sensor to capture an image of the reflected illumination pattern. The corneal topography optical housing is coupled to the illumination system and the mobile communication device, wherein the corneal topography optical housing supports and aligns the illumination system with the image sensor of the mobile communication device. The corneal topography optical housing includes an imaging system coupled to the image sensor.
