SMILE Pro Surgery Outcomes for High vs. Moderate-to-Low Astigmatism

A retrospective study of 60 eyes from 30 patients who underwent bilateral SMILE Pro refractive surgery using the VISUMAX 800 platform. The dataset, authored by Yuchen Mei and shared under CC-BY-4.0, compares visual, refractive, and vector outcomes between eyes with high (> 2.00 D) and moderate-to-low (≤ 2.00 D) astigmatism at 6 months post-surgery. Results include uncorrected distance visual acuity, correction index, angle of error, and higher-order aberration measurements.

Use Cases

• Compare vector outcomes like correction index and angle of error between different levels of preoperative astigmatism.
• Analyze the relationship between intraoperative decentration and postoperative higher-order aberrations.
• Evaluate the efficacy of automated cyclotorsion compensation (OcuLign) in SMILE Pro procedures.
• Assess the statistical significance of nominal differences in residual cylinder and difference vector after false discovery rate correction.

Strengths

• Includes data from a contralateral-eye study design, allowing for paired comparisons within the same patient.
• Reports specific 6-month follow-up metrics, including vector parameters and higher-order aberrations.
• Provides concrete statistical comparisons (p-values) for outcomes between the two astigmatism groups.

Limitations

• The sample size is modest, with 30 patients (60 eyes), as noted in the study conclusion.
• The range of high astigmatism is narrow, focusing on values slightly above 2.00 diopters.
• Column-level documentation is absent; field semantics must be inferred after download.
