This retrospective study evaluated the outcomes of BI-KPro implantation in 118 patients. Material: The mean age of the patients was 56.76 \u00b1 14.24 years. Indications for keratoprosthesis implantation were as follows: graft failure, 47 (39.83%); ocular burn, 38 (32.20%); neurotrophic keratopathy, 11 (9.32%), mucous membrane pemphigoid 9 (7.67%); autoimmune, 6 (5.08%); Stevens\u2013Johnson syndrome, 4 (3.39%); and aniridia (2.54%). Methods: The surgeries were performed between March 2019 and June 2022 at a single clinical center in two locations. The postoperative visual acuity, complications, and need for additional surgical procedures were analyzed. Results: The Best Corrected Visual Acuity before surgery was 0.01 \u00b1 0.006. After one year (V1), it was 0.30 \u00b1 0.27; at two years (V2), it was 0.27 \u00b1 0.26; and at three years (V3), it was 0.21 \u00b1 0.23. The percentage of patients with visual acuity better than 0.1 on the Snellen chart was 37.29% after 1 year, 49.35% after 2 years, and 46.81% after 3 years of follow up. The most common complications were glaucoma (78 patients; 66.1%), corneal melting (22 patients; 18.6%), and retroprosthetic membranes (20 patients; 17.0%). Conclusions: The BI-KPro can significantly improve visual acuity. The worst long-term results were obtained in the group of patients with autoimmune diseases; therefore, careful consideration should be given to implanting BI-KPro in this group. The high incidence of de novo glaucoma or the progression of pre-existing glaucoma suggests the need for careful monitoring.<\/jats:p>","DOI":"10.3390\/jcm13040975","type":"journal-article","created":{"date-parts":[[2024,2,9]],"date-time":"2024-02-09T09:04:01Z","timestamp":1707469441000},"page":"975","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Outcomes of Boston Keratoprosthesis Type I Implantation in Poland: A Retrospective Study on 118 Patients"],"prefix":"10.3390","volume":"13","author":[{"given":"Ewa","family":"Wr\u00f3blewska-Czajka","sequence":"first","affiliation":[{"name":"Clinical Department of Ophthalmology, Faculty of Medical Sciences in Zabrze, Medical University of Silesia, 40-760 Katowice, Poland"},{"name":"Ophthalmology Department, Railway Hospital in Katowice, 40-760 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8768-1691","authenticated-orcid":false,"given":"Dariusz","family":"Dobrowolski","sequence":"additional","affiliation":[{"name":"Clinical Department of Ophthalmology, Faculty of Medical Sciences in Zabrze, Medical University of Silesia, 40-760 Katowice, Poland"},{"name":"Ophthalmology Department, Railway Hospital in Katowice, 40-760 Katowice, Poland"},{"name":"Department of Ophthalmology, Santa Barbara Hospital, 41-200 Sosnowiec, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7295-4936","authenticated-orcid":false,"given":"Adam","family":"Wyl\u0119ga\u0142a","sequence":"additional","affiliation":[{"name":"Health Promotion and Obesity Management Unit, Department of Pathophysiology, Faculty of Medical Sciences, Medical University of Silesia, 40-760 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ula V.","family":"Jurkunas","sequence":"additional","affiliation":[{"name":"Cornea Center of Excellence, Schepens Eye Research Institute, Massachusetts Eye and Ear Infirmary, Department of Ophthalmology, Harvard Medical School, Boston, MA 02114, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6707-5790","authenticated-orcid":false,"given":"Edward","family":"Wyl\u0119ga\u0142a","sequence":"additional","affiliation":[{"name":"Clinical Department of Ophthalmology, Faculty of Medical Sciences in Zabrze, Medical University of Silesia, 40-760 Katowice, Poland"},{"name":"Ophthalmology Department, Railway Hospital in Katowice, 40-760 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"863","DOI":"10.1016\/j.ophtha.2023.03.012","article-title":"Global Trends in Blindness and Vision Impairment Resulting from Corneal Opacity 1984\u20132020: A Meta-analysis","volume":"130","author":"Wang","year":"2023","journal-title":"Ophthalmology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1175","DOI":"10.1016\/j.survophthal.2022.01.005","article-title":"The historical development and an overview of contemporary keratoprostheses","volume":"67","author":"Moshirfar","year":"2022","journal-title":"Surv.
