An 81-year-old woman with systemic hypertension and atrial fibrillation underwent Descemet membrane endothelial keratoplasty (DMEK) for visual acuity of counting fingers because of postphacoemulsification bullous keratopathy with no prior episodes of inflammatory eye disease (Figure 1A). Her best-corrected visual acuity (BCVA) improved to 20/40 two weeks later, limited because of a preexisting corneal scar.
