[Application of the Salzburg reading desk in accommodation and presbyopic research].

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.
