Computer-assisted eye examination. VI. Identification and correction of errors in the Refractor III system for subjective examination.
A computer-assisted subjective eye examination was administered to 80 patients. They were also examined in the conventional manual way. The results of the computer-assisted examination were compared with those obtained by conventional subjective methods to identify errors of hardware, software, and optometric flow charting and other problems. An 87.5% satisfactory prescription level was found for the distance prescription. The 12.5% unsatisfactory results are accounted for by several kinds of error. The percentage of unsatisfactory refractive results was greater for near than for distance measures because of special flow-chart and software problems, which were subsequently corrected. With implementation of the changes initiated as a result of this investigation, satisfactory refractive results approaching 95% can be expected.
