title: A clinical study of the autorefractor, an antomatic refracting device.
abstract: Four hundred eyes were examined with the Autorefractor, an automatic refracting machine, and the results compared with those found by standard techniques of clinical refraction with and without cycloplegia. Agreement was good for spherical power, cylindrical power and spherical equivalents, but less so for cylinder axes.
