Purpose:
To report a case of Ahmed tube exposure secondary to Prokera implantation.
Methods:
Case report.
Results:
We present a 48-year-old woman who developed tube erosion after penetrating keratoplasty and Prokera implantation for dense vascularized corneal scar. The patient subsequently underwent wound revision with repeat scleral patch graft and closure of the conjunctival defect.
Conclusions:
The case presented demonstrates that caution should be exercised in using this implant in patients who have irregular elevations of the ocular surface because of glaucoma drainage devices.
