Supplementary File 2: Dual-Applanation Model for Goldmann Tonometry Correction

Gaetano Barbaro's supplementary file presents a physical-mathematical model for correcting Goldmann applanation tonometry measurements. The model incorporates patient-specific corneal biomechanical properties, such as central corneal thickness, curvature radius, and elastic modulus, to quantify systematic error. It was published on figshare in April 2026 under a CC-BY-4.0 license.

Use Cases

• Correcting intraocular pressure measurements based on corneal thickness and elasticity parameters described in the model.
• Simulating the impact of corneal curvature variations on tonometry error as outlined in the results.
• Developing personalized tonometry protocols using the integrated anatomical and biomechanical parameters.
• Analyzing the relationship between systematic error and the four defined physical forces (F1-F4).

Strengths

• The model is grounded in a transparent physical force balance, as described in the methods.
• It integrates three key patient-specific corneal parameters: thickness, curvature radius, and elastic modulus.
• The file is openly available under a CC-BY-4.0 license.

Limitations

• The dataset is a 120.8 KB PDF file; the underlying data tables or simulation results are not directly accessible.
• Column-level documentation is absent; field semantics must be inferred from the model description.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
