Risk of Endophthalmitis in Boston Type 1 Keratoprosthesis Combined with Vitrectomy and Silicone Oil Insertion

Figure 1

Kaplan–Meier graph of the incidence of endophthalmitis in the Boston type 1 keratoprosthesis (uncombined KPro) group versus combined KPro, pars plana vitrectomy, and silicone oil insertion group (KPro + PPV + SOI), with the number of subjects at risk at different time points listed underneath the figure. The 2-year cumulative (Cum) survival ratio was 68.8% in the KPro group, versus 100% in the KPro + PPV + SOI group ().
