The Beginnings of Konan Medical


Konan Medical Inc. in Japan (“KMI”), was established in 1947 in Hyogo Japan after WWII by a group of camera enthusiasts.

KMI has been in the specular microscope business since 1979 and holds over 1,600 patents including many remarkable products such as the balloon camera (meteorology) 1955, radar camera 1956, electrofax copy machine 1960, the first disposable camera 1963, and the specular microscope 1979.

As the market leader in specular microscopy, Konan has a significant share of the healthy and growing market for devices used to image and assess the corneal endothelium both for clinical and donor corneas / eye banking.
