Refractive dependent models incorporating ocular elements predict myopia-related spherical aberration. While models show promise, they overestimate peripheral astigmatism and have limited success predicting average eye refraction changes.

Area of Science:

  • Ophthalmic optics
  • Visual science
  • Biomedical engineering

Background:

  • Understanding ocular optics is crucial for correcting refractive errors.
  • Previous models often simplify ocular components, limiting predictive accuracy.
  • Refractive changes in the periphery are complex and influenced by multiple optical elements.

Purpose of the Study:

  • To develop and evaluate refractive-dependent ocular models.
  • To incorporate gradient index and aspheric surfaces for improved accuracy.
  • To assess model performance in predicting peripheral refraction and aberrations.

Main Methods:

  • Constructed refractive-dependent models using existing data.
  • Included gradient index lens and aspheric corneal, lens, and retinal surfaces.

  • Developed centered and decentered versions to simulate optical element alignment variations.

    • Main Results:

    • The centered model accurately predicted increased spherical aberration in myopia.
    • Models showed good prediction of peripheral horizontal vs. vertical mean sphere changes.
    • Peripheral astigmatism was overestimated by approximately 50% in the centered model.
    • The decentered model demonstrated limited success in predicting average eye peripheral refraction.

    Conclusions:

    • Refractive-dependent models can capture key aspects of ocular optics, including myopic spherical aberration.
    • Current models require refinement, particularly for peripheral astigmatism and decentered optical elements.
    • Further development is needed to improve the predictive accuracy of ocular models for individual refractive states.
