About

Justification. Fuchs' corneal endothelial dystrophy (FECD) is one of the main causes of corneal transplantation. In many cases, the corneal decompensation derived from this dystrophy is triggered as a consequence of cataract surgery, so the dilemma of facing isolated cataract surgery or combined with endothelial keratoplasty is often raised.

Objective. The present study aims to evaluate and select the most important predictive factors for corneal decompensation after cataract surgery in patients with FECD.

Method. Prospective observational study of the preoperative and intraoperative variables presumably associated with postoperative corneal edema requiring Descemet stripping endothelial keratoplasty (DMEK). Consecutive candidates for cataract surgery with FECD will be selected and anterior segment imaging will be performed, along with a complete ophthalmological examination. Clinical, pachymetric, tmographic, densitometric, specular microscopy, and intraoperative variables will be registered.

Enrollment: 68 patients
