[Prognosis of penetrating keratoplasty in secondary endothelial atrophy of diverse etiology].

Endothelial atrophy following cataract extraction is an increasingly important indication for perforating keratoplasty (PK). Other significant indications for PK are the treatment of endothelial atrophy following vitreous/retinal surgery for perforating injuries or primary retinal pathology. We evaluated the first year post-operative course of fourteen patients that underwent PK: 7 patients with silicon-oil induced keratopathy (group I), and 7 patients with endothelial atrophy following anterior segment surgical procedures (group II). On follow-up, group II exhibited a significant improvement of visual acuity. In group I, despite the clarity of the graft, there was no improvement of vision because of the development of retrocorneal membranes, or pre-existing or progressive retinal changes.
