Expert computer systems can accurately prescribe eyeglass prescriptions for myopia. Both example-based and rule-based systems demonstrated high accuracy in predicting sphere and cylinder powers for low refractive errors.

Area of Science:

  • Optometry and Vision Science
  • Artificial Intelligence in Healthcare
  • Computer Science Applications

Background:

  • Expert computer systems offer potential for automating optometric tasks.
  • Developing AI tools for ophthalmic lens prescription is an emerging field.
  • Previous research has explored rule-based systems in clinical decision support.

Purpose of the Study:

  • To develop and evaluate example-based and rule-based expert systems for optometric applications.
  • To assess the accuracy of AI systems in prescribing sphere and cylinder powers for myopic patients.
  • To explore the feasibility of using AI for ophthalmic lens correction.

Main Methods:

  • Utilized NeuroShell (example-based) and EXSYS (rule-based) software.
  • Trained NeuroShell with patient data including chief complaint, habitual prescription, and best refraction.

  • Developed a simple rule set for EXSYS to predict refractive corrections.

    • Main Results:

    • NeuroShell predicted sphere and cylinder powers within 0.25 diopters of optometrist prescriptions 97% and 98% of the time, respectively.
    • EXSYS predicted sphere powers within 0.25 diopters of prescribed powers for 100% of test eyes.
    • Both systems showed high accuracy with simple refractive error cases.

    Conclusions:

    • Expert computer systems can be effectively taught to prescribe ophthalmic lens corrections.
    • AI-driven prescription systems show promise for optometric practice.
    • The approach could be extended to more complex refractive conditions and patient populations.
