Abstract
Purpose: To compare anatomical and functional results between three types of keratoprosthesis (KPro) in chemical injury and autoimmune disease. Methods: 70 clinically comparable cases were included as follows: Boston KPro Type 1 25 eyes, osteo-odonto-keratoprosthesis (OOKP) 23 eyes, Tibial bone KPro 22 eyes. Survival times for anatomical and functional success were evaluated with Kaplan-Meier estimations and Log-rank tests. KPro exchange was considered a complication, not as failure. Results: Prosthesis retention in chemical injury group at 5 years was 86% for OOKP, 100% for Tibial bone KPro, and 65% for Boston KPro (p = 0.09), while in the autoimmune disease group it was 66% for Tibial bone KPro and 50% for Boston KPro (p = 0.19; OOKP only one case). Functional success in the chemical injury group at 5 years was 86% for OOKP, 84% for Tibial bone KPro and 71% for Boston KPro (p = 0.38), while in the autoimmune group, it was 44% for Tibial bone KPro and 15% for Boston KPro (p = 0.15; OOKP only one case). The post-operative complications in all groups were: retinal detachment, vitreous hemorrhage, endophthalmitis, retro-prosthetic membrane, uncontrolled glaucoma, the last two being more common in Boston KPro. Conclusions: For both diagnoses, chemical injury and autoimmune diseases, there was a tendency for better long-term anatomical and functional results with Tibial bone KPro followed by OOKP and Boston KPro Type 1. However, these results were not statistically significant.
