An integrated system for measuring static and dynamic accommodation with a Canon Autoref R-1 refractometer

An integrated system is described which we have found useful for efficiently collecting and analyzing both static and dynamic accommodation data using the Canon Autoref R-1 refractometer. The system consists of hardware modifications and software designed to both facilitate the measurement of accommodation and to process the resulting data. Several features of the Canon R-1, which may not be evident to some users, are also described. A program written in Microsoft C/C++ running under DOS, and designed for use on a PC, is available from the authors upon request.
