A New Standard in Biometric IOL Power Calculation
Accuracy of calculation determines the refractive outcome. The DUDO Calculator 6th Generation utilizes more than 40 biometric parameters combined with AI modeling, delivering ophthalmologists higher refractive predictability and stability of outcomes than any other currently available formula.
Why Accurate Calculation Matters
The calculation formula is a fundamental tool in intraocular lens (IOL) implantation. Based on biometric parameters of the eye, it enables the surgeon to determine the optimal dioptric power of the implanted IOL.
- ensures prediction of the planned refraction
- minimizes the need for additional correction or reoperation
- directly impacts visual quality in daily activities
Without precise calculation, the surgical outcome cannot be clinically reliable
When Traditional Formulas Fall Short...
SRK/T, Holladay - Accurate only in standard eyes; fail significantly in atypical parameters.
Barrett Universal II - Reliable in most cases, but limited for premium IOLs
Hill-RBF - Employs AI, but accuracy depends directly on the extent of the database.
Consequence: Up to 15–20% of patients experience residual refractive error after surgery, requiring additional correction.

A Clear Result Without Compromises
Surgeons often face a dilemma: Which formula to choose? Each may yield slightly different results, forcing compromise. The DUDO Calculator 6th Generation eliminates this dilemma.
- Integrates the strongest aspects of multiple formulas while eliminating their limitations.
- Provides a clear, clinically accurate result ready for immediate application.
- Allows the surgeon to fully concentrate on the patient and the procedure instead of mathematical comparisons.
- Less variability between formulas = higher predictability of outcomes.

Frequently Asked Questions
To determine the optimal dioptric power of an intraocular lens in cataract and refractive surgery.
Because these have limitations in atypical eyes and with premium IOLs. The DUDO Calculator uses a broader biometric dataset and AI, achieving higher accuracy.
Hill-RBF relies on database coverage. The DUDO Calculator combines database learning with each patient’s individual biometry (>40 parameters).
Yes. It supports monofocal, toric, EDOF, and trifocal IOLs.
No. It processes data from standard biometers if the required parameters are available.
Continuously, based on new clinical data, several times a year.
Exactly – the algorithm provides a single, clear result, eliminating dilemmas and compromises.
Yes. Calculations are continuously compared with real-world clinical outcomes, validated at multiple centers.
Tested on borderline cases; thanks to AI modeling, it shows higher stability than traditional formulas.
Yes. It is optimized for altered corneal profiles after previous refractive procedures.
At minimum: axial length, keratometry, anterior chamber depth, and lens thickness. When available, it also processes higher-order aberrations and extended datasets.
Yes. Results are available in PDF or CSV format for patient records.
No. While it provides unmatched precision for trifocal and toric IOLs, it also improves accuracy with monofocal lenses.
Immediate – results are generated within seconds.
Continuous development and adaptation to emerging trends in ophthalmic surgery, especially new generations of premium IOLs.
