Supplementary File 1: Dual-Applanation Model for Goldmann Tonometry Correction

162.1 KB PDF authored by Gaetano Barbaro, uploaded to figshare on 2026-04-29. The document presents a novel physical-mathematical model to quantify systematic error in Goldmann applanation tonometry by incorporating patient-specific corneal biomechanical properties. It analytically evaluates the influence of central corneal thickness, curvature radius, and elastic modulus on intraocular pressure measurement accuracy.

Use Cases

• Developing personalized intraocular pressure correction algorithms based on corneal biomechanical parameters.
• Analyzing the relationship between corneal thickness and Goldmann tonometry error as described in the model.
• Simulating the impact of corneal curvature radius on applanation force balance.
• Evaluating the clinical applicability of a dual-zone applanation prism measurement technique.

Strengths

• Model integrates three key anatomical and biomechanical parameters: central corneal thickness, mean apical curvature radius, and corneal elastic modulus.
• The document provides a transparent, biomechanically grounded method for correcting GAT measurements.
• License is CC-BY-4.0, allowing for open sharing and reuse.

Limitations

• The dataset is a single 162.1 KB PDF file, indicating a limited scope of data.
• Row count and column-level documentation are absent; data semantics must be inferred from the text.
• The description is detailed but does not provide sample data or explicit column definitions.
