Temporary Keratoprosthesis with Penetrating Keratoplasty in Conjunction with Pars Plana Vitrectomy for Repair of Retinal Detachments in Patients with Anterior and Posterior Segment Pathology.

Purpose The purpose of this study is to review the visual and anatomic outcomes of combined anterior and posterior segment surgery for retinal detachment (RD) repair. Methods and Patients: Eight patients with combined retinal and corneal disease underwent combined temporary keratoprosthesis with penetrating keratoplasty (PKP) combined with pars plana vitrectomy for RD repair with silicone oil tamponade. Visual and anatomic outcomes were reviewed retrospectively. Follow up ranged from 12 months to 37 months. Results Preoperative visual acuity ranged from light perception to hand motion. All but one case had proliferative vitreoretinopathy present at the time of surgery. Postoperative visual acuity ranged from hand motion to light perception. At the most recent follow up visit, all of the patients had attached retinas, no patients had phthisis bulbi, and all but one patient had a clear cornea. However, three of these cases (38%) required repeat RD repair and one of them also required repeat PKP, which was performed at the time of retinal repair. Conclusion Combined full-thickness PKP and RD repair has good anatomic outcomes and is an efficient way to treat complex anterior and posterior segment pathology. Although post-operative visual function is limited, almost all patients were agreeable to repeat surgery if they were presented with the choice again.
