Abstract

BACKGROUND:

In severe forms of ocular surface disorders keratoprostheses provide the ultimate possibility to restore vision. They are made of an optical cylinder integrated with a supporting biocompatible or biological haptic.

CASE REPORT:

We report on two patients with different types of keratoprostheses. An 88-year-old woman with ocular pemphigoid received in 1970 a bilateral osteo-odonto-keratoprosthesis (Strampelli). A 59-year-old man with refractory corneal ulcer after corneal grafting received in 2003 a keratoprosthesis with supporting Dacron tissue (Pintucci).

RESULTS:

The course 35 years after implantation of the osteo-odonto-keratoprosthesis was uneventful. Histologically there were no signs of loosening, rejection or infection. The autologous dentin, which was used for the fixation, was still present. The eye with the Dacron fixated prosthesis (Pintucci) had to be enucleated due to a loosening with endophthalmitis one and a half year after implantation.

CONCLUSIONS:

Keratoprostheses with autologous fixation often show good long-term results. On the other hand, prostheses with synthetic material are more often complicated by dislocation and inflammation.
