PurposeTo report the outcomes of implantation of the Boston Type I keratoprosthesis in three patients with Acanthamoeba keratitis (AK), a severe infection that can lead to significant visual loss.ObservationsCase series reporting three patients with difficult cases of AK that needed multiple corneal transplantations and glaucoma surgeries. All patients were implanted with the Boston Type I keratoprosthesis device. The main outcomes measure were the visual function and anatomical retention after implantation of the Boston Type I keratoprosthesis. All patients retained the device over the long-term and had good visual function. In one patient a retroprosthetic membrane developed and in another patient an epithelial lip developed over the anterior surface of the keratoprosthesis. The visual acuities range from 20/25 to 20/80 in the implanted eyes.Conclusions and importanceThe Boston Type I keratoprosthesis resulted in good anatomic and functional results after multiple graft failures after AK.

“…This limits successful surgical outcome of anterior lamellar keratoplasty also 5. Keratoprosthesis is a viable option for patients with corneal blindness who are poor candidates for keratoplasty 3. In the first case, two times graft failure occurred following multiple episodes of rejection.…”

“…The presence of LSCD as well as corneal neovascularisation puts these patients at high risk for allograft rejection as well as surface breakdown 2. Boston type I keratoprosthesis is a viable option in patients with repeated graft failure and/or with severe ocular surface disease 3. These cases report good visual outcome in patients with XP with corneal involvement using type I keratoprosthesis after repeated graft failure as well as when used as a primary procedure.…”

SUMMARYA 6-year-old girl, a case of xeroderma pigmentosum (XP), presented with a visual acuity (VA) of 20/20 and 20/400 in the right and left eye, respectively. For a diagnosis of vascularised corneal scar, penetrating keratoplasty was performed in the left eye twice and ultimately graft failed following multiple episodes of rejection. Type I keratoprosthesis was performed in the left eye. She continues to maintain VA of 20/40 in the left eye for more than a year. Similarly, a 24-year-old man, a case of XP, presented with VA of finger counting at 1 metre in both eyes. Ocular examination showed bilateral vascularised corneal scar and conjunctivalisation. Type I keratoprosthesis was performed as primary procedure in the left eye. He maintains a VA of 20/30 for more than a year. Type I keratoprosthesis could be a primary procedure for visual rehabilitation in patients with XP with severe ocular surface disease. BACKGROUND

“…In the last few decades, keratoprostheses have become more and more popular in non‐standard situations of patients requiring penetrating keratoplasty, with a high risk for graft rejection. Such conditions have a history of one or more unsuccessful keratoplasties, stem cell deficiency, or immunologic problems . More than 6000 implantations of Boston keratoprostheses were reported by the Massachusetts Eye and Ear Infirmary between 2002 and autumn 2011 .…”
