Corneal Surgery Residual Thickness Predictor

Ensuring Safe Surgical Outcomes

This advanced calculator predicts post-operative residual stromal thickness following corneal refractive procedures. By integrating pre-operative pachymetry data with planned ablation profiles, this tool helps surgeons maintain safe residual bed thickness thresholds, minimizing the risk of post-surgical ectasia. Essential for LASIK, PRK, and SMILE procedures, it provides instant visualization of tissue removal patterns and safety margins, supporting evidence-based surgical planning and enhanced patient safety protocols.

AIOLsci – Patient-Specific IOL Performance Predictor

Personalized IOL Selection Through Advanced Optical Modeling

AIOLsci revolutionizes IOL selection by providing objective, patient-specific predictions of visual outcomes. This sophisticated platform bridges laboratory physics and clinical decision-making by combining empirically measured IOL wavefronts with personalized aspheric corneal models (R, Q). Unlike standard approaches that rely on average eye models, AIOLsci computes through-focus MTF to quantify exactly how a specific IOL will perform in your patient’s unique optical system. The platform features a comprehensive library of IOL designs based on proprietary optical bench measurements, capturing real manufacturing performance including asphericity, refractive profiles, and diffractive elements. Manufacturer-neutral and compatible with any biometer or topographer, AIOLsci delivers results through intuitive contrast curves and depth-of-field estimates, enabling direct comparisons between monofocal, EDOF, and multifocal options. This ensures each IOL choice is optimally tailored to the individual patient’s corneal optics rather than statistical averages, ultimately improving surgical outcomes and patient satisfaction in modern cataract surgery.

Toric Phakic IOL Optimal Rotation Calculator

Minimize Residual Astigmatism in Phakic Lens Implantation

This interactive tool determines and visualizes the optimal rotation angle of a toric phakic intraocular lens (e.g., ICL, IPCL, or similar) to minimize postoperative residual astigmatism. It performs full vector analysis of corneal and lenticular astigmatism (J0/J45), converts toric power between the phakic IOL plane and corneal plane using the Distance between the corneal and phakic IOL plane (ELP equivalent), and displays optimization curves alongside frontal and surgical views. Designed as a decision-support and teaching tool for refractive surgeons performing phakic IOL implantation.

PEARL-DGS IOL Power Calculator

Open-Source AI-Based Formula for Complex Cases

The PEARL-DGS (Postoperative spherical Equivalent prediction using ARtificial Intelligence and Linear algorithms) formula represents a breakthrough in IOL power calculation, combining thick lens equations with machine learning models to predict posterior corneal radius and the theoretical internal lens position (TILP). Developed by Debellemanière, Gatinel, Saad and published as open-source software, this advanced calculator features three specialized platforms. The « Regular Eyes » section handles standard cataract cases with customizable options for keratometric index, biometer type, and IOL model specifications, including support for meniscus designs. The « Complex Eyes » platform addresses challenging scenarios including post-refractive surgery eyes (myopic/hyperopic LASIK/PRK), radial keratotomy, scarred corneas, and ICL-implanted eyes, with automatic adjustments to lens position predictors and corneal power calculations. The « Second Eyes » section leverages first-eye surgical data to enhance prediction accuracy through back-calculation algorithms. Optional parameters including LT, CCT, and WTW measurements further refine predictions when available, making PEARL-DGS a comprehensive solution for achieving optimal refractive outcomes across the full spectrum of clinical presentations.

Navigate the complexities of astigmatism management with our comprehensive vector analysis tool. This calculator combines multiple astigmatic components—corneal, lenticular, and residual—providing both numerical and graphical representations of resultant cylinder power and axis. Ideal for toric IOL planning, crossed-cylinder calculations, and understanding obliquely crossed cylinders, this tool simplifies complex optical calculations while maintaining mathematical precision.

Wavefront to Radial Vergence Power Map Converter

From Microns to Diopters – Clinical Translation

Bridge the gap between wavefront analysis and clinical refraction with this powerful conversion tool. Transform Zernike polynomial coefficients expressed in microns into clinically interpretable refractive power distribution maps in diopters. Unlike traditional wavefront displays showing optical path differences, this simulator generates radial vergence maps that directly reveal myopic and hyperopic zones across the pupil aperture. This intuitive visualization provides immediate clinical relevance, allowing practitioners to correlate aberrometry findings with manifest refraction measurements and better understand the refractive impact of higher-order aberrations on visual performance.

Dive deep into the complex relationship between corneal asphericity (Q-factor) and optical performance with this comprehensive simulation tool. This advanced analyzer demonstrates how variations in corneal asphericity directly influence spherical aberration (Z4,0), vergence distribution patterns, and the induction of useful depth of focus. Through interactive 3D visualizations and real-time calculations, clinicians can explore how changing Q-values affect wavefront aberrations, visualize the resulting intrapupillary power distribution (induced multifocality), and quantify the impact on through-focus visual performance. Essential for presbyopia-correcting procedures and aspheric IOL selection, this tool bridges theoretical optics with clinical applications by illustrating the delicate balance between corneal shape and visual quality.
