Preserved corneal plugs and associated systems, devices and methods for fabricating corneal plugs

Abstract

A corneal plug comprising preserved human corneal tissue with an encircling groove along the perimeter of the tissue. A method for creating a corneal plug comprising punching a plug from a corneal allograft that has been preserved, trimming the plug to a selected thickness with a cutting device, and cutting an encircling groove around the plug. A device for creating a corneal plug comprising an applicator, an applicator support fixedly attached to the applicator, a blade base configured for free rotation about the applicator and relative to the applicator support, the blade base defining an opening for the applicator, and one or more supports disposed on the blade base configured to releasably secure a blade to the blade base adjacent to the opening, wherein upon rotation of the blade base the blade forms an encircling groove in a cornea plug.
