Cataract Surgery Refractive Outcomes In Pterygium Eyes

20 unilateral eyes underwent staged cataract surgery following pterygium excision. This dataset compares four keratometric methods for predicting refractive outcomes, including postoperative K, predicted K, preoperative K, and fellow-eye K. The study validates a regression-based prediction model using actual postoperative data.

Use Cases

• Compare mean K, spherical equivalent, refractive error, and absolute refractive error across four keratometric methods using paired analysis.
• Validate a regression-based keratometric prediction model against postoperative K values for refractive error calculation.
• Perform exploratory analyses on the influence of preoperative corneal parameters, such as corneal radius of curvature, on refractive predictability.
• Conduct sensitivity analyses on refractive outcomes after exclusion of cases involving toric intraocular lens (IOL).

Strengths

• Data includes 20 unilateral eyes with paired analysis for controlled comparison.
• Compares four distinct keratometric methods: postoperative K, predicted K, preoperative K, and fellow-eye K.
• Study validated a specific regression model using CASIA2 anterior segment parameters and the Barrett Universal II formula.

Limitations

• Small sample size of 20 eyes limits statistical power and generalizability of findings.
• Retrospective study design may introduce selection bias compared to prospective trials.
• Data scope is limited to a specific surgical context (staged cataract surgery after pterygium excision).
