Zusammenfassung:Purpose to describe the functional results and sight threatening post‐operative complications of Type I Boston Keratoprosthesis. Methods retrospective descriptive study of Boston Keratoprosthesis patients from two European eye centers. Results A total of 66 eyes were included for analysis. Mean follow‐up time was 28 months. Majority of patients had more than 2 penetrating keratoplasties, primary clinical diagnosis are presented. Mean preoperative best corrected visual acuity was 2.05, mean best ever achieved post‐operative best corrected visual acuity was 1.16 and final mean postoperative best corrected visual acuity was 1.47 . The most common sight‐threatening complications were as follows: retroprosthetic membrane, retinal/choroidal detachment, infectious keratitis, endophthalmitis, peripheral retinal occlusive vasculitis and prosthesis extrusion. Management of complications are discussed. Conclusion 95 % retention rate with overall improvement in visual acuity demonstrates that Type I Boston Keratoprosthesis is a good alternative to cases of multiple graft failure due to various primary clinical diagnoses. Complications must be detected early on and managed accordingly to ensure success of the procedure.
