Understanding IOL Studio
FROM OPTICS TO VISION
IOL Studio is an advanced simulation and analysis software suite for TEMPO-MENTOR, developed to evaluate intraocular lens (IOL) performance beyond traditional optical metrics. It helps manufacturers understand how lens design choices translate into expected visual performance under realistic and standardized conditions.
By combining clinically relevant visual metrics, ISO-aligned evaluation methods, configurable model eyes, and advanced simulation tools, IOL Studio supports the entire IOL development process, from early R&D and design optimization to pre-clinical evaluation, validation, and documentation.

EXPLORE IOL STUDIO CAPABILITIES
Three integrated areas of analysis within one software suite.
White Light Simulation
This simulation evaluates IOL performance under polychromatic (white-light) conditions, providing results that better reflect real-world vision compared to monochromatic analysis. It applies a white-light processing algorithm to compute PSF and through-focus MTF curves using photopic or scotopic spectra, in line with ISO requirements.
White-light simulation does not change the type of results generated, but how they are computed. By weighting multiple wavelengths according to a defined spectrum, it delivers optical performance data that is more representative of clinical and regulatory testing conditions.
Polychromatic optical processing: Compute PSF and through-focus MTF curves using full-spectrum light instead of single- wavelength analysis.
Photopic and scotopic spectra: Select photopic or scotopic spectral weighting to reflect different lighting conditions and regulatory scenarios.
ISO-aligned evaluation: Generate white-light optical results suitable for pre-clinical workflows and alignment with ISO 11979-2 expectations.
Consistent comparison framework: Apply white-light processing to existing analyses and comparisons, without changing measurement workflows or interpretation tools.
Decentration & Tilt Simulation
This evaluates the impact of IOL decentration and tilt on visual performance when the lens is implanted in the eye. It allows assessment of how sensitive an IOL design is to misalignment during implantation, supporting robustness evaluation under realistic conditions.
Decentration and tilt scenarios can be applied to simulate expected implantation tolerances and to analyze their effect on optical and visual performance, as required in ISO-compliant pre-clinical workflows.
Decentration and tilt simulation: Simulate tilted and decentered IOL positions to evaluate the impact of implantation misalignment on lens performance.
Sensitivity to misalignment: Assess how robust an IOL design is to realistic positioning errors during surgery.
ISO-aligned evaluation: Support pre-clinical analysis of decentration and tilt effects in line with ISO expectations.
Consistent performance comparison: Compare IOL designs under identical misalignment conditions to support R&D decisions and documentation.
Visual Metrics and Predicted Visual Acuity
This analysis provides advanced metrics to characterize IOL performance and better relate bench measurements to expected clinical vision. It computes commonly used visual metrics from the optical results and generates Predicted Visual Acuity through-focus curves in logMAR, supporting workflows aligned with the ANSI approach where MTFA is used to correlate with visual acuity.
Clinically relevant metrics: Compute MTFA and additional visual metrics widely used in publications to support performance comparisons and clinical correlation.
Predicted Visual Acuity (logMAR): Generate through-focus predicted visual acuity curves based on optical performance, supporting interpretation across the full defocus range.
Visual Strehl OTF: Calculate Visual Strehl OTF, combining the eye’s contrast sensitivity function with the OTF, for robust evaluation beyond standard MTF.
Clear lens comparison: Compare designs using consistent metrics and graphs (including X/Y performance where applicable) to support R&D decisions and communication.
Letter & Halos Simulation
This simulation enables visualization of how an IOL may affect perceived image quality when combined with a model eye. It provides intuitive visual representations of vision at distance, intermediate, and near, helping to illustratethe impact of multifocality and optical design on perceived image quality.
Letter-based simulations use optotypes of different sizes to show how clearly a patient may see at different defocus positions. In addition, disk-based simulations allow visualization of dysphotopsia effects such as halos and glare.
Letter-based visual simulation: Visualize contrast and sharpness using optotypes at distance, intermediate, and near vision to illustrate expected visual performance.
Halos and glare visualization: Use disk-based simulations to observe halo patterns and glare effects associated with multifocal and EDoF IOL designs.
Defocus-dependent perception: Explore how perceived image quality changes across defocus positions, supporting interpretation of optical performance beyond numerical metrics.
Intuitive lens comparison: Compare IOL designs using visual representations that are easy to understand for clinical, R&D, and commercial discussions.
Configurable Arizona Model Eye
The Arizona model eye plugin allows users to simulate realistic visual conditions by customizing the anatomical parameters of the eye model. Based on the Jim Schwiegerling model, this digital simulation replaces the crystalline lens with an IOL, offering a standardized environment for accurate optical evaluation.
Customizable Eye Anatomy: Adjust parameters like corneal radii, conic constants, thickness, refractive index, ACD, and IOL-pupil distance for realistic simulation.
Standardized Optical Evaluation: Based on the Jim Schwiegerling model eye, replacing the crystalline lens with an IOL for consistent performance assessment.
Dynamic Configuration Display: Automatically flags non-default values with an asterisk (*) in output graphs for clear traceability.
Enhanced MTF Simulation: Enables more accurate and relevant analysis across different eye geometries and design scenarios.
Zernike Cornea Model Eye
This plugin replaces the standard corneal model with two customizable surfaces – the anterior and posterior surfaces of the cornea – described using Zernike coefficients. Users can import a CSV file containing patient-specific or theoretical data and adjust parameters such as corneal thickness, anterior chamber depth (ACD), and refractive indices for the cornea, aqueous, and vitreous.
It enables advanced simulations to evaluate IOL performance under realistic visual conditions, making it a valuable tool for understanding lens behaviour in aberrated eyes and assisting with IOL selection tailored to individual patients.
Custom Corneal Modeling: Simulate anterior and posterior surfaces using Zernike coefficients.
CSV Import: Load patient-specific or theoretical data via a structured template.
Configurable Parameters: Modify corneal thickness, anterior chamber depth (ACD), and refractive indices for cornea, aqueous, and vitreous.
Realistic Simulations: Evaluate IOLs under complex or aberrated visual conditions.
Project Integration: Parameters are saved and applied throughout the MTF analysis.
