Wide-angle optical model of the eye.

Area of Science:

• Ophthalmology
• Optical Engineering
• Biomedical Engineering

Background:

• Designing accurate wide-angle optical eye models is crucial for understanding visual function.
• Existing models often rely on generalized biological and physical eye data.
• A data-driven approach using in vivo measurements offers a more personalized modeling strategy.

Purpose of the Study:

• To investigate and validate a second approach for designing wide-angle optical eye models.
• To determine the average axial spherical aberrations in emmetropic eyes using in vivo measurements.
• To refine eye model parameters by fitting model calculations to measured optical performance.

Main Methods:

• Measured axial spherical aberrations in 100 eyes of 50 emmetropic volunteers.
• Employed a model-fitting approach using in vivo optical performance data.
• Calculated unknown eye model parameters such as corneal asphericity and lens properties.

Main Results:

• Established an average curve representing axial spherical aberrations in emmetropic eyes.
• Demonstrated the feasibility of calculating detailed eye model parameters from in vivo measurements.
• Provided a validated method for creating personalized optical eye models.

Conclusions:

• The in vivo measurement and model-fitting approach is a valid method for developing accurate wide-angle optical eye models.
• This approach allows for the calculation of specific ocular parameters, leading to more precise eye simulations.
• The findings contribute to advancing the understanding and simulation of the human eye's optical performance.
