Abstract:

A device transfers donor endothelial cells to the cornea of a recipient without injuring the cells or the cornea during the transfer process. The device transfers living endothelial cells from a donor to a recipient with minimal or no trauma. The device includes a handle, an irrigation tube lengthwise within the handle, a button upon the handle concentric with the irrigation tube, a tapered nose opposite the button, a forward tube extending outwardly from the nose, and a platform joined to the irrigation tube. The forward tube has an elliptical cross section and two beveled features. The platform has two wings that curl gently around donor tissue upon retracting the platform into the forward tube. The handle has a groove for a stem of a knob that surgeon presses and pulls to move the platform.
