Medium term results in keratoprostheses with biocompatible and biological haptic

Abstract

Fixation of the KPro by a root of the patient s own tooth (OOKP) leads to the best results in the long-term follow up, as our results as well as the literature demonstrate. As long as a KPro is in place, the visual acuity is as good as the retinal function. For the ranking of different types of KPro, the percentage and the duration of the anatomic success are most important. The comparability of the various KPro results may be limited, since the patients were not randomised and the four groups differ in number.

Long-term functional and anatomical results of osteo- and osteoodonto-keratoprosthesis

“…Our lower results might be attributed to the fact that 37% of our patients live outside Spain, including the Middle-East (26%), which makes frequent patient visits and regular control difficult. For OKP, our results of 80% anatomical survival at 1.5 years were similar to the 75% reported by Hille [5] (four cases).…”

“…Falcinelli [3] reported 85% anatomical survival at 18 years post-op (181 cases) for OOKP and Hille [5] 100% survival at 8 years post-op (25 cases). Our results for OOKP were 68% at 8 years and 59% at 18 years post-op.…”

“…A common approach for such a comparison is to define a certain lower limit of visual acuity (VA) as the terminal event, and then use survival analysis, such as Kaplan-Meier [1,3,5]. Often, only an empirical density functions for VA is given [2,7].…”

Glaucoma in Modified Osteo-odonto-keratoprosthesis Eyes: Role of Additional Stage 1A and Ahmed Glaucoma Drainage Device–Technique and Timing

“…6 Drainage devices therefore form the mainstay of glaucoma management in these eyes. 1,7 However, details regarding the technique of shunt procedures using these devices at various stages of the MOOKP surgery have not been described earlier in literature. In this paper we have described the technique and timing as well as analyzed the outcomes of the Ahmed glaucoma drainage device for glaucoma in eyes undergoing the MOOKP procedure.…”

Serial 3-Dimensional Computed Tomography and a Novel Method of Volumetric Analysis for the Evaluation of the Osteo-Odonto-Keratoprosthesis

“…[1][2][3][4][5] Invented by Strampelli 6 in 1963, and later modified by Falcinelli et al, 4 OOKP uses the patient's own single-rooted tooth and surrounding alveolar bone to support an optical cylinder made of polymethylmethacrylate (Fig. 1).…”
