USPTO Patent. Patent No.: US 10,129,450 B2.

A system and method for ophthalmological imaging is provided for use with a mobile processing device, wherein the mobile processing device comprises a camera lens, light source, and processor configured to process images captured, received, and/or delivered by the mobile processing device. The mobile processing device adapted ophthalmological instrument system comprises housing segments, circuitry, lights, and a frustum cone, wherein the frustum cone comprises reference lines of a plurality of circular, frusto-conical, alternating transparent and opaque concentric rings in the conical surface in optical alignment with the mobile processing device's camera lens and subject's central cornea and/or tear-film layer(s). Reflections of the reference lines off the cornea and/or tear-film layer are imaged by the mobile processing device and analyzed by software applications downloaded to and/or accessed by the smart-phone's processor(s), wherein data of shape, structure, composition, function, and/or power of the cornea and/or tear-film layer(s) are determined by methods comprising one or more image processing and/or computer vision functions configured to produce topographic data. The processor of the mobile processing device can provide and/or receive specific information to/from other instruments and/or users through a communications network.
