Abstract

Purpose:

To describe specific maneuvers and technical modifications to the standardized “no-touch” technique of Descemet membrane endothelial keratoplasty (DMEK) to successfully handle the presence of a glaucoma drainage device (GDD) tube in the anterior chamber of an eye with a failed primary penetrating keratoplasty (PK) graft.

Methods:

A 42-year-old male patient underwent DMEK because of a failed primary PK graft in his phakic right eye. The patient was then evaluated at 3 and at 6 months after surgery.

Results:

A modified no-touch DMEK technique proved a feasible treatment option for a decompensated primary PK graft in the presence of a long GDD tube.

Conclusions:

With specific technical modifications DMEK can be successfully performed in eyes with decompensated primary PK grafts in the presence of a long GDD tube. The very thin DMEK graft allows positioning between the GDD tube and the failed PK graft, leaving the tube in place.
