Second opinion: A computer expert system designed to aid in the determination of spectacle lens prescriptions

1 April 1994


INTRODUCTION: Expert systems (ESs) are computer programs that can simulate the decision making ability of human experts. In this project, an ES was developed that used optometric data and decision rules to produce spectacle lens prescriptions.

METHODS AND MATERIALS: A commercially available shell program was used to produce the ES. Decision rules were derived from clinical experience and standard references. The resultant ES was capable of prescribing spherical and cylindrical lenses, and bifocal adds that would give maximum acuity consistent with a maximum probability of patient acceptance.

DISCUSSION: The ES developed in this project demonstrates how programs of this type can be used to analyze optometric data and offer a second opinion on the proper lens prescription for a patient.
