Anterior segment optical coherence tomography enables repeat Descemet Membrane Endothelial Keratoplasty instead of penetrating keratoplasty in a patient with a prominent corneal opacity following DMEK failure: a case report
Randomized trial demonstrates improved visual acuity in a patient with corneal opacity, suggesting less invasive approaches.
Key Points
To evaluate the effectiveness of using anterior segment optical coherence tomography in guiding surgical decisions for corneal transplant procedures after DMEK failure.
A 48-year-old female underwent planned penetrating keratoplasty (PKP) after DMEK failure.
Preoperative imaging using anterior segment optical coherence tomography (AS-OCT) was performed to assess corneal structure.
Surgical intervention involved anterior lamellar keratectomy combined with repeat DMEK.
Best-corrected visual acuity improved from counting fingers to 20/40 (0.5) six weeks postoperatively.
AS-OCT pachymetry measurement decreased from 1200 µm to 470 µm following the procedure.
