Cataract Surgery Refractive Outcomes in Pterygium Eyes

Keiji Sato's 2026 study provides a paired analysis of refractive outcomes for 20 unilateral eyes with pterygium undergoing staged cataract surgery. The dataset compares four keratometric methods, including predicted and postoperative K values, for parameters like spherical equivalent and absolute refractive error.

Use Cases

• Validate the regression-based keratometric prediction model's performance against postoperative K values for spherical equivalent and refractive error.
• Compare mean K, spherical equivalent, refractive error, and absolute refractive error across four keratometric methods using the described statistical tests.
• Conduct sensitivity analyses on refractive outcomes after excluding cases with toric intraocular lenses.
• Perform exploratory analyses to assess the influence of preoperative corneal parameters, such as corneal radius of curvature, on refractive predictability.

Strengths

• Data is derived from a structured, peer-reviewed medical study validating a specific prediction model.
• Analysis includes multiple key refractive parameters: mean K, spherical equivalent, refractive error, and absolute refractive error.
• Dataset is openly licensed under CC BY 4.0 for reuse.

Limitations

• Very small sample size of only 20 eyes limits statistical power and generalizability of findings.
• Retrospective study design introduces potential biases compared to a prospective trial.
• The 21.6 KB file size indicates a highly summarized dataset, likely containing aggregate results rather than raw patient-level data.
