Boston kpro type i: Outcomes

Abstract

Keratoprosthesis has been used in adults since the mid-twentieth century. In early comparisons between PKs and KPros, the failure rate of PKs in high-risk patients can approach to 56 % at 3 years. However, with the advent of the Boston type I device, the outcomes of artificial keratoprosthesis implantation improved greatly. Best visual outcomes can be achieved in much less time with faster improvements overall. Complications include recurrent epithelial defects, retroprosthetic membranes, glaucoma, and a lifelong risk of endophthalmitis. There are multiple ways to prophylactically avoid these complications. In 2003, following the favorable experiences with the Boston KPro type 1 device in adults, the first infant keratoprosthesis procedure was performed. Because implantation of Boston type I keratoprostheses is still a balance between faster recovery and possible vision-threatening complications, is still an option even for people with poor prognosis, and necessitates a multidisciplinary approach and careful long-term follow-up.
