Simultaneous Deep Anterior Lamellar Keratoplasty and Descemet Membrane Endothelial Keratoplasty for Corneal Endothelial Failure With Stromal Scarring

ABSTRACT: We present an alternative surgical procedure including simultaneous deep anterior lamellar keratoplasty (DALK) and Descemet membrane endothelial keratoplasty (DMEK) in a case with endothelial failure and stromal scarring. A 62-year-old woman presented with vision loss caused by pseudophakic bullous keratopathy. While waiting for a corneal transplant, the patient developed infectious keratitis, which was treated with medication. Although the keratitis healed, it left a scar. To improve the patient's vision, a corneal transplant surgery that included simultaneous DALK and DMEK was performed. Postoperatively, the corneal graft was clear, and the Descemet membrane was well attached. However, there was an interface haze because of residual stromal tissue. The patient's best-corrected visual acuity improved from hand motion to 0.2 (decimal). This combined procedure allows for lamellar keratoplasty in cases with coexistence of corneal endothelial and stromal involvement.
