Boston Keratoprosthesis (Boston KPro Type I)
A prosthetic corneal strategy for selected eyes in which conventional corneal transplantation has a high risk of failure and the ocular surface can support a Type I keratoprosthesis.
Clinical overview
Indications, strategy and clinical context
The Boston Type I Keratoprosthesis is one of the most established artificial cornea systems for eyes in which conventional corneal transplantation has a high risk of failure but the ocular surface remains capable of supporting a Type I approach.
The aim of this section is to show the device in a clinical, real-world manner: not as an abstract diagram, but as a surgical solution seen at the slit lamp in actual postoperative eyes.
CE marked for the European market
Boston Keratoprosthesis Type I received European Conformity (CE) marking in 2014,
confirming conformity with the applicable European requirements at the time of certification.
Regulatory information · NICE ↗
Indications
High-risk corneal blindnessRepeated graft failure, selected chemical injuries and ocular surface conditions where a donor cornea has a low chance of long-term clarity.
Strategy
Not every severe eye needs OOKPWhen the surface is suitable, Boston KPro may provide a less complex reconstructive pathway than osteo-odonto or tibial bone techniques.
Follow-up
Long-term surveillance is essentialSurface stability, epithelial status, glaucoma and posterior segment monitoring remain critical after surgery.
