The Boston KPro type I is used after standard penetrating keratoplasty has failed or when They showed that Boston KPro I improved visual acuity and was more effective than penetrating keratoplasty in patients with severe corneal opacity who have already had a failed corneal graft. The Boston KPro is used after standard penetrating keratoplasty has failed or when such a transplant would be unlikely to succeed. [1] In this method, a transparent prosthetic device is applied instead of a cornea to restore the patient’s vision. The Boston Keratoprosthesis (KPro) is the most widely used artificial cornea or keratoprosthesis. The KPro Study Group was established in 1990 to foster clinical and basic research on keratoprosthesis, synthetic corneas and artificial corneal implants. The type I design is used much more frequently than the type II which is reserved for severe end stage dry eye con What is a Boston Keratoprosthesis? Boston keratoprosthesis (KPro) is an artificial cornea made of acrylic plastic. The donor graft is slid down the stem of the optic along with the back plate in place. This was due to reduced aqueous flow and penetration to the donor carrier cornea placed the 3mm optical stem, permanent KPro device, installed in the 9. An anterior vitrectomy was also performed in most eyes, giving more room for an optical cylinder. 1%) as a result of device extrusion from sterile corneal melt in 2 eyes and infectious keratitis in 1 eye. The Dohlman-Doane keratoprosthesis, most commonly referred to as the Boston Keratoprosthesis (KPro), is manufactured under the auspices of the Harvard Medical School affiliated Massachusetts Eye and Ear Infirmary. This is a biannual meeting of keratoprosthesis (artificial cornea) experts and aficionados all over the world, whereby we exchange our experiences, new techniques and results of research for end stage corneal diseases which are otherwise Keratoprosthesis (KPro) devices have the remarkable ability to restore vision in patients suffering from corneal blindness who are poor candidates for traditional penetrating keratoplasty.

The grant will support our clinical activities as well as the manufacturing and automation process which will enable us Boston Type II was created for later-stage disease; however, when compared with OOKP, higher rates of tissue melting and aqueous leak occurred in Type I and 2. The authors reported a best-achieved median visual acuity of 20/100 We also have a renewed Memorandum of Understanding between the Asia Cornea Society and the KPro Study Group. In partial thickness, or anterior lamellar technique, the KeraKlear KPro requires removal of a small portion of the anterior corneal tissue in order to be implanted (Vargas JM, Shiuey Y, A foldable artificial cornea for treatment of cornea blindness, personal communication at ASCRS, 2012). According to the World Health Organization (WHO), approximately two million new cases of corneal blindness are reported annually. In 1992, the FDA approved the Boston KPro, the first artificial replacement cornea. While corneal transplantation can successfully restore sight in many, corneal graft survival decreases in eyes with chronic inflammation and corneal vascularization. This Memorandum of Understanding (MOU) expresses the general understanding and intentions of the ACS www. Funding for this conference was made possible (in part) by 1R13EY036277-01A1 from the National Eye Institute. 22 Venugopal A, Rathi H, Rengappa R, Ravindran M, Keratoprostheseis (KPRO) Keratoprosthesis implantation is a procedure that involves full-thickness removal of the cornea and replacement by an artificial cornea. 0 mm optic) Fig. Corneal melting after B-KPro is a relatively rare event, occurring in 3% of eyes during the first three years of postoperative follow-up. 1 days. Complications can include melting/extrusion of the implant, infection, fresh human donor corneas as carriers for the Boston KPro. Sina Sharifi elsewhere in this newsletter, gamma or E-beam irradiated corneal We also have a renewed Memorandum of Understanding between the Asia Cornea Society and the KPro Study Group. “The innovative approach behind CorNeat KPro coupled by the team’s execution ability present a unique opportunity to finally address the global corneal blindness challenge,” said Prof. Keratoprosthesis (KPro) or artificial cornea transplant is the treatment of choice for patients with end-stage corneal blindness. 4 Before surgery is performed, patients are informed and educated on proper contact Assemble the keratoprosthesis by sandwiching the corneal graft between the front and back plates of the KPro device. Gilad Litvin, MD, CorNeat Vision's co-founder, chief medical officer, and the inventor of the CorNeat KPro, said in a statement that being in the room with the patient was a “surreal” experience. KPro Millions of people worldwide are bilaterally blind due to corneal diseases including infectious etiologies, trauma, and chemical injuries. 9 years Purpose: The purpose of this study was to evaluate the long-term incidence, risk factors, and the management of corneal melt following Boston type I keratoprosthesis (B-KPro I) implantation. Ra'anana, Israel Terms of Use. However, eyes with KPro can experience various complications, including the development of retroprosthetic membrane (RPM). A KPro with melting carrier cornea and fungal infiltrate around the stalk of the prosthesis. Most of the available literature pertains to glaucoma management in eyes with Boston Type I Kpro. The KeraKlear Artificial Cornea is a medical device for the treatment of cornea blindness. Made of a central lens from polymethyl methacrylate (PMMA) delivering 42 D of optical power at the corneal plane, it features a spherical design to compensate for potential decentration. Before Cataract Surgery. 25. Dr. Privacy Policy The review of level II evidence suggests that the BI-KPro for artificial corneal transplantation can lead to vision recovery and vision improvement in patients whose corneal conditions are not amenable to keratoplasty with human cadaveric corneal tissue. The Boston type 1 keratoprosthesis (KPro) is indicated in patients with poor vision because of corneal blindness in whom the chance of success of penetrating keratoplasty (PKP) is low, often due to a history of multiple failed grafts, limbal stem cell deficiency, severe neurotrophic corneal conditions or corneal vascularization []. 5±2. The summit celebrated Dohlman’s legacy with recent Miro Cornea UR (Miro Vision): A synthetic, “bio-coated” keratoprosthesis that can support epicorneal or intrastromal implantation, according to the company’s website; 4 indicated for eyes bilaterally blind from corneal disease or injury.

We compare visual outcomes of eyes undergoing primary Kpro to eyes that had a secondary Kpro following penetrating keratoplasty. 6% (11/ 43) of patients with autoimmune disease failed to retain the KPro. 2 45 When to reconstruct the Ocular Surface and when to do KPro Jose Luis Güell MD, PhD 12. 9415 Campus Point Drive, La Jolla, CA . 0 mm, making the introduction of the KPro–donor corneal complex into the opening a small challenge that can be easily overcome. 1 – Preoperative opaque cornea left eye. Dear KPro aficionados, Two important announcements: 1) Professor James Chodosh and the MEEI team are planning the meeting ” Boston Keratoprosthesis Type I: Fundamentals and New Directions ” to be held at the Massachusetts Eye and Ear Infirmary on Wednesday, May 13, 2020 from 12 noon to 5 PM, with reception to follow. Improving outcomes and reductions in devastating compli Dear KPro aficionados, Two important announcements: 1) Professor James Chodosh and the MEEI team are planning the meeting ” Boston Keratoprosthesis Type I: Fundamentals and New Directions ” to be held at the Massachusetts Eye and Ear Infirmary on Wednesday, May 13, 2020 from 12 noon to 5 PM, with reception to follow. 2015). However, there are situations Keywords: keratoprosthesis, OOKP, KPro, Boston KPro, cornea, ocular surface. Although several of these devices are still in preclinical trials, they show promise in animal models. 2 C). 5 mm. 3 45 Different folks, different strokes: reconstructing techniques for extruded KPros Jaime Etxebarria MD 12.
