PURPOSE: To determine the presentation, risk factors, and outcomes of keratolysis after Boston type I keratoprosthesis (B-KPro). METHODS: Retrospective chart review. RESULTS: A total of 16 (14%) of the 110 eyes (96 patients) which underwent B-KPro implantation developed keratolysis at an average 20 ± 11 months. Retroprosthetic membrane (RPM), infectious keratitis, and corneal dellen were identified in 31%, 25%, and 13% of corneal melts, respectively...

A 25-year-old Syrian male with a previous episode of Stevens-Johnson syndrome with bilateral corneal cicatrization previously underwent surgery for Type 1 Boston Keratoprosthesis (K-Pro). Sixteen months after the K-Pro surgery, the patient presented with decreased vision to hand motion and microbial keratitis of the graft around the K-Pro with purulent discharge. Corneal scrapings were nonrevealing. B-scan in 3 days showed increased debris in the vitreous cavity and thickened retinochoroidal layer. Intravitreal tap and injections of vancomycin and ceftazidime were performed...

OBJECTIVES: To determine the rate of biofilm formation on bandage contact lenses worn by patients with the Boston type 1 keratoprosthesis (K-Pro) while on prophylactic topical vancomycin versus linezolid. METHODS: Patients wearing a bandage contact lens (BCL) with a K-Pro were eligible for enrollment. After irrigation of the ocular surface with 5% povidone-iodine solution, each patient was placed on either topical vancomycin 15 mg/mL or linezolid 0.2% BID for one month...

PURPOSE: To describe the results of Boston keratoprosthesis implantation in a patient with Stevens-Johnson syndrome following autologous submandibular gland transplantation. DESIGN: Observational case report. METHODS: We report the case of a man diagnosed with Stevens-Johnson syndrome. Autologous submandibular gland transplantation was performed in the right eye in 2008 to ameliorate tear film deficiency. Due to the improvement in the microenvironment of the ocular surface, Boston keratoprosthesis implantation was performed in the right eye in 2011...

PURPOSE: To compare the long-term clinical outcomes of fresh versus frozen corneal graft carriers for the Boston Keratoprosthesis type 1 (B-KPro). DESIGN: Prospective, single-center, nonblinded, randomized controlled trial. All participants were followed through the initial study protocol of 24 months and were approached to enter an extension phase, with continuing follow-up visits to 60 months. PARTICIPANTS: All patients undergoing B-KPro surgery between October 2008 and December 2009 by a single experienced surgeon at the Centre Hospitalier de l'Université de Montréal using an allograft carrier were considered...

PURPOSE: To review the incidence and features of vitreoretinal complications of a permanent Boston keratoprosthesis and to report the use and outcomes of 23-gauge vitrectomy to manage vitreoretinal pathology. DESIGN: Retrospective non-comparative, interventional case series. SUBJECT, PARTICIPANTS: 27 eyes of 27 patients managed with a Boston keratoprosthesis at Moorfields Eye Hospital over a 3-year period. METHODS: All eyes that underwent pars plana vitrectomy (PPV) and had at least 6 months follow-up were analysed with a specific focus on the anatomical and histological characteristics of retinal detachment and outcomes of surgery...

PURPOSE: To report a case of recalcitrant Prototheca spp. keratitis and endophthalmitis in a patient with Stevens-Johnson syndrome (SJS) and Boston type 1 keratoprosthesis (B1 KPro). METHODS: Case report. RESULTS: A 67-year-old female with a history of SJS with chronic severe ocular surface disease in her monocular left eye underwent placement of a B1 KPro. Her course was subsequently complicated by persistent Prototheca spp. keratitis and endophthalmitis requiring ongoing treatment with triazole and polyene antifungal agents and multiple surgical revisions of her keratoprosthesis...

S Siebelmann, B Bachmann, A Lappas, T Dietlein, M Hermann, S Roters, C Cursiefen, P Steven
BACKGROUND: Optical coherence tomography (OCT) is the clinical gold standard for anterior and posterior segment imaging. Since OCT devices have been integrated into surgical microscopes, this technique is also available intraoperatively in anterior segment surgery. OCT is well established in imaging very thin or transparent structures as they appear in corneal or glaucoma surgery. Therefore, intraoperative OCT can deliver important information for the surgeon which is superior to the normal surgical microscope...

PURPOSE: To evaluate outcomes after Auro keratoprosthesis (kpro) implantation. METHODS: Retrospective observational case series. The records of all patients who were implanted with Auro kpro from December 2012 to August 2015 at a single institute were retrospectively analyzed to evaluate preoperative characteristics, postoperative outcomes, and complications. RESULTS: Fifteen cases were included in the study. Failed graft was the most common indication for the surgery (n = 14; 93...

PURPOSE: To determine the rate of Boston type 1 keratoprosthesis (Kpro)-related corneal melts, leaks, and extrusions requiring surgical repair and to analyze possible risk factors and visual outcomes. METHODS: Retrospective chart review of 110 patients (128 eyes) who received a Kpro between November 2004 and December 2010 (average follow-up of 29 mo). The rate of corneal complications, risk factors for melts, and postmelt repair visual outcomes were evaluated. RESULTS: Twenty eyes from 18 patients developed Kpro-related melts requiring surgical repair...
