An apparatus for enabling corneal topography includes an attachment to align a placido disc illumination system with a camera of a mobile communication device. The placido disc illumination system generates concentric rings and reflects the concentric rings off a cornea. A portion of the reflected concentric rings are utilized to confirm vertex distance. The apparatus further comprises a memory, a processor, and computer-readable instructions in a mobile communication device. The camera captures an image of reflected concentric rings and communicates the captured image of the reflected concentric rings to an external computing device. A method for performing corneal topography utilizes a mobile computing and/or communication device, projects a plurality of peripheral concentric rings onto a subjects cornea and projects center rings onto the subjects cornea. The method further includes capturing, via a smartphone camera, an image of the projected peripheral concentric rings and the center rings.
