Background:
Expert systems (ESs) are computer programs that simulate the decision-making ability of human experts. In this project, an ES was developed that used optometric data and decision rules to determine spectacle lens prescription powers.
Methods:
Decision rules derived from clinical experience and standard references were provided to a commercially available shell program to create an ES called Second Opinion. The ES determined spherical, cylindrical, and add powers designed to provide maximum acuity consistent with a high probability of patient acceptance.
Conclusions:
Second Opinion demonstrates how a computer program can be used to analyze optometric data and offer suggestions regarding lens prescriptions.
