Boston type 1 keratoprosthesis: the New York Eye and Ear experience

Influence of Primary Diagnosis and Complications on Visual Outcome in Patients Receiving a Boston Type 1 Keratoprosthesis

“…Using the same VA criterion (0.05), Verdejo-Gomez et al [16] found a success rate of 83% (n = 12). Using 0.10 VA, but with different follow-up times, Greiner et al [14 ]had success in 89% (n = 36 at 1 year), Bradley et al [4] in 77% (n = 30), Aldave et al [17] in 68% (n = 27 at 1 year), Goldman et al [18] in 63% (n = 107), Zerbe et al [12 ]in 57% (n = 141) and Patel et al [19] in 43% (n = 50) of cases. This shows that our VA success rate is consistent with previous reports.…”

Predictors of Visual Outcomes Following Boston Type 1 Keratoprosthesis Implantation

“…[1][2][3][4][5][6][7][8] The US Food and Drug Administration cleared the device for use in 1992, and prior to 2004, less than 100 devices had been implanted. As of M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 3 keratoprosthesis procedures or permanent keratoprosthesis using devices other than Boston type 1 KPro were also excluded.…”

Vitreoretinal aspects of permanent keratoprosthesis

“…6,15,41,51,75,76,79 Case series with more than 50 eyes have consistently reported incidence rates of approximately 50%. 2,3,47,67 In one of the largest series, consisting of 265 eyes, the incidence was 31.7%. 78 The time interval between surgery and development of RPM varies from weeks to months, with appearance as early as 1 week and as late as 49 months.…”

“…2 Despite treatment, many RPMs recur with rates approaching 65%, and some eyes require multiple treatments. 2,67,76 Hence, research has focused on methods of preventing RPM formation. Several Boston KPro design modifications, such as a threadless KPro 76 and devices with titanium backplates, may reduce risk of RPM formation.…”
