PURPOSE: To evaluate the indications, outcomes and complications of Auro keratoprosthesis (a low-cost design based on type I Boston Keratoprosthesis) in the end-stage corneal disease in a preliminary study.
METHODS: In this prospective interventional study, 10 eyes of 10 patients with an end-stage corneal disease underwent implantation of Auro keratoprosthesis with the mean follow-up of 14.5±2.1 months. The indications included multiple failed grafts (n=7), aphakic bullous keratopathy (n=2) and chemical injury (n=1). The additional intraoperative procedures performed were synechiolysis (n=9), cataractous lens extraction (n=2), Ahmed glaucoma valve implantation (n=1) and vitreoretinal surgery (n=1). Antibiotic prophylaxis was administered postoperatively, and patients were followed up at 1 week, 2 weeks, 1 month and thereafter at monthly intervals. The main outcome measures were best corrected visual acuity (BCVA), retention of prosthesis, complications and need for secondary surgical interventions.
RESULTS: The most common indication for keratoprosthesis implantation was graft failure (7/10, 70%). The postoperative BCVA improved to ≥20/200 in six patients. Nine out of 10 patients had retained keratoprosthesis. The complications seen were inflammatory debris behind keratoprosthesis (n=4), retroprosthetic membrane (n=2), glaucoma (n=4), small (<2 mm) sterile stromal necrosis or erosions at the graft edge (n=3) and microbial keratitis (n=1). Explantation of the keratoprosthesis was performed in one eye due to fungal keratitis.
CONCLUSIONS: Auro keratoprosthesis, a low-cost keratoprosthesis, is a viable option in the end-stage corneal disease in this preliminary study. Multicentre studies with long-term follow-up are required to conclusively prove its safety and efficacy.
