Repeat Dmek With Glaucoma Tube Shunt Revision For Bullous Keratopathy

This surgical video shows how a failed DMEK can be replaced with a fresh transplant in the setting of bullous keratopathy caused by a glaucoma tube shunt. Further, it shows how the shunt may be safely and easily revised to facilitate the operation.

Bullous keratopathy is a corneal disease with many different causes. The basic problem is failure of the cornea’s pump cell layer, causing corneal clouding, swelling, and the formation of painful fluid-filled blisters on the surface of the eye. Complicated prior surgery (especially cataract or glaucoma surgery) is the most common cause, followed by certain kinds of corneal infections.Bullous keratopathy is curable with surgery to replace the cornea’s failed endothelial pump layer. Frequently, eyes with bullous keratopathy also have other problems – with the iris, the lens, etc. Therefore, these may need to be fixed, as well, to prevent the bullous keratopathy from returning.
