Zusammenfassung
Insbesondere nach refraktiv-chirurgischer Presbyopiekorrektur ist die postoperative Erhebung der Lesefähigkeit der bei weitem wichtigste Parameter, um die zur Verfügung stehenden Verfahren miteinander vergleichen zu können. Da jede Person ihre optimale Lesedistanz bei Bedarf verändert und auch der jeweiligen Lichtsituation anpasst, erscheint die Überprüfung der Lesefähigkeit unter fix vorgegebenen Prüfdistanzen wenig sinnvoll. Seit dem Jahr 2004 arbeitet die Universitätsklinik für Augenheilkunde und Optometrie der PMU Salzburg daran, ein entsprechendes standardisiertes Gerät zu entwickeln, welches dem Probanden erlaubt, seinen individuellen Leseabstand bei der Erhebung seiner individuellen Leseschärfe zu verwenden. Dies ermöglicht es uns nun automatisch, objektive, valide und damit auch vergleichbare Ergebnisse im Bezug auf die funktionelle Lesefähigkeit zu erheben.
Abstract
The determination of reading acuity is still the most important clinical examination, whenever the potential benefits of ”presbyopic surgery” are compared. Reading distance – the by far most critical parameter in testing reading acuity – seems to be quite variable for every patient tested, whenever patients are allowed to freely choose a subjectively convenient reading distance. Therefore, measuring reading acuity with a fixed reading distance does not allow conclusions to be drawn on the ”every-day reading ability” of individual patients. Since 2004, the Eye Clinic of Salzburg University has been continuously working on the development of a standardised device that enables clinicians and researchers to systematically evaluate every patient’s individual reading performance under standardised conditions.
