Entwicklung eines Gerätes zur Druckmessung an der Aachener Keratoprothese

Purpose: Postoperative glaucoma is one of the major complications observed in patients with keratoprostheses. The optical components of the majority of KPros are rigid and inflexible, which prevents indirect tonometry with common methods. This study confirms that the Aachen-KPro allows measurements of the intraocular pressure (IOP) due to its flexible optical part with a modified Schiotz tonometer. Methods: The Aachen-KPro was placed in a special chamber where pressure can be generated and monitored by a transducer. Measurements were performed with common ophthalmologic methods. The results were compared to the initial pressure values in the chamber. Results: With the Goldmann tonometer, the Tono-Pen and the topography system (Technomed), no significant pressure changes could be observed. The results of the Schiotz tonometer were promising. It was slightly modified and standard curves with different weights could be obtained. Conclusions: With a modified Schiotz tonometer, it is possible to detect elevated IOPs. Modifying this common instrument is inexpensive and can be performed easily. This advantage of the Aachen-KPro permits early management of postoperative high tension glaucoma.
