Keratoprosthesis: Current global scenario and a broad Indian perspective.

Indian J Ophthalmol 2018 05;66(5):620-629

Department of Oral and Maxillofacial Surgery, SRM Dental College, Bharathi Salai, Ramapuram, Chennai, Tamil Nadu, India.

Keratoprosthesis (Kpro) forms the last resort for bilateral end-stage corneal blindness. The Boston Type 1 and 2 Kpros, the modified osteo-odonto Kpro and the osteo-Kpro are the more frequently and commonly performed Kpros, and this review attempts to compile the current data available on these Kpros worldwide from large single-center studies and compare the indications and outcomes with Kpros in the Indian scenario. Although the indications have significantly expanded over the years and the complications have reduced with modifications in design and postoperative regimen, these are procedures that require an exclusive setup, and a commitment toward long-term follow-up and post-Kpro care.

[Keratoprosthesis with Biological Haptic - The Düsseldorf-Offenburg-Experience with Osteo-Odonto- and Tibia-Keratoprosthesis].

Klin Monbl Augenheilkd 2017 Jun 6;234(6):763-769. Epub 2017 Jun 6.

Augenklinik, Klinikum Offenburg.

In severe ocular surface disease with limbal stem cell deficiency associated with severe dry eye, penetrating keratoplasty is likely to fail. In these cases, and provided the posterior segment is normal, keratoprosthesis surgery (KPro) can achieve visual rehabilitation. In KPros with an autologous biological haptic, a bone-tooth-complex (osteo-odonto-keratoprothesis, OOKPro) or a piece of tibial cortex (tibia-keratoprosthesis, TKPro) is used to carry a PMMA cylinder.

A review of corneal melting after Boston Keratoprosthesis.

Semin Ophthalmol 2014 Sep-Nov;29(5-6):349-57

Department of Ophthalmology, Massachusetts Eye and Ear Infirmary , Boston, Massachusetts , USA.

Use of the Boston Keratoprosthesis (B-KPro) has grown significantly, both in the United States and overseas over the course of the last decade. It is the most frequently employed keratoprosthesis for the management of complex corneal blindness. Improving outcomes and reductions in devastating complications such as corneal melting and infection have motivated this increase in use. Read More

Contact lens surveillance cultures in Boston type 1 keratoprosthesis patients.

Eye Contact Lens 2013 Mar;39(2):175-8

Department of Ophthalmology and Visual Sciences, University of Illinois Medical Center and Health System, Chicago, IL, USA.

Objectives: To describe surveillance cultures of bandage contact lenses (BCL) in patients with a history of Boston type 1 keratoprosthesis (KPro) surgery.

Methods: An institutional review board-approved retrospective review of patients with a history of Boston type 1 KPro surgery and BCL cultures between July 2008 and June 2010. Data on demographics, preoperative diagnosis, topical corticosteroid and antibiotic use, duration of BCL wear, clinical diagnosis of microbial keratitis or endophthalmitis, and culture results were recorded.

Eyelid procedures in patients who have undergone Boston keratoprosthesis surgery.

Ophthalmic Plast Reconstr Surg 2012 Jul-Aug;28(4):286-8

Department of Ophthalmology and Visual Sciences, University of Iowa, Iowa City, Iowa 52242, USA.

Purpose: Artificial corneas or keratoprostheses such as the Boston keratoprosthesis (KPro) are being used more frequently to provide a clear corneal window in patients with severe corneal disease. A significant percentage of patients who undergo Boston KPro implantation require subsequent eyelid surgery. However, few articles in peer-reviewed literature evaluate the indication and outcome of eyelid procedures after Boston KPro implantation. Read More

Vitreoretinal surgery in the setting of permanent keratoprosthesis.

Arch Ophthalmol 2012 Apr;130(4):487-92

Weill Cornell Medical College, Rockefeller University/Sloan-Kettering Institute Tri-Institutional MD-PhD Program, New York, NY 10021, USA.

Objectives: To evaluate the surgical management of vitreoretinal pathology in patients with a permanent Boston Type 1 keratoprosthesis (hereafter referred to as a KPro) in the era of small-gauge vitrectomy techniques.

Methods: Retrospective review of 23 small-gauge vitreoretinal surgical procedures during or after Dohlman-Doane KPro placement in 14 eyes.

Results: Established and innovative techniques were used, including sutureless small-gauge vitrectomy, temporal positioning of surgeon, long-term tamponades, and exploratory endoscopy. Read More

Presumed endophthalmitis following Boston keratoprosthesis treated with 25 gauge vitrectomy: a report of three cases.

Graefes Arch Clin Exp Ophthalmol 2010 Mar 12;248(3):447-50. Epub 2009 Dec 12.

Department of Ophthalmology, G.Gennimatas Hospital, University of Athens, Athens, Greece.

Background: Although endophthalmitis is known to occur frequently in patients with KPros, the management remains a challenge both due to the lack of evidence and the exceptionality of the examination and the therapeutic approach.

Materials And Methods: Three patients implanted with Boston keratoprosthesis for management of ocular cicatricial pemphigoid and severe alkali injury presented with severe late-onset (10-24 months post-operatively), presumed bacterial endophthalmitis. Three-port 25-gauge (g) pars plana vitrectomy was performed in all patients; vitreous samples were acquired and intravitreal vancomycin and cefuroxime were administered. Read More

[Clinical management of severe ocular surface disease].

Authors:
J Stoiber G Grabner

Klin Monbl Augenheilkd 2005 Jul;222(7):533-51

Universitätsklinik für Augenheilkunde und Optometrie an der Paracelsus Medizinischen Privatuniversität Salzburg.

Severe ocular surface diseases, such as Stevens-Johnson syndrome, ocular cicatricial pemphigoid or severe ocular burns may result in a significant loss of corneal stem cells, eventually leading to vision impairment or even corneal blindness. In case of unilateral involvement, limbal autografting, by means of transplanting limbal stem cells from the healthy fellow eye, has proved to be an effective procedure for restoring the integrity of the ocular surface. Limbal allografts may be performed in patients with bilateral disease, however, systemic immunosuppression is mandatory in these cases, with a long-term outcome that is frequently reduced compared to limbal autografts due to acute or chronic graft rejection.

Clinical results of implantation of the Chirila keratoprosthesis in rabbits.

Br J Ophthalmol 1998 Jan;82(1):18-25

Lions Eye Institute, Perth, Western Australia.

Aims/background: An ideal keratoprosthesis (KPro) would closely resemble a donor corneal button in terms of its surgical handling, optics, and capacity to heal with host tissue in order to avoid many of the complications associated with the KPros which are currently in clinical use. This study was carried out to assess the long term clinical outcomes on implantation of the core and skirt poly(2-hydroxyethyl methacrylate) KPro in animals.

Methods: 20 KPros were made and implanted as full thickness corneal replacements into rabbits and followed for up to 21 months to date. Read More
