Table 4_Vector outcomes after SMILE pro with the VISUMAX 800 for high versus moderate-to-l

30 patients (60 eyes) underwent bilateral SMILE Pro refractive surgery with the VISUMAX 800 platform. The study compares 6-month visual, refractive, and vector outcomes between eyes with high astigmatism (>2.00 D) and their contralateral eyes with moderate-to-low astigmatism (≤2.00 D). The dataset, authored by Yuchen Mei and last updated in June 2026, is a single-center retrospective analysis.

Use Cases

• Compare vector analysis parameters like correction index and angle of error between different astigmatism severities.
• Analyze the relationship between preoperative cylinder magnitude and postoperative higher-order aberrations such as trefoil, spherical aberration, and coma.
• Evaluate the performance of automated cyclotorsion compensation (OcuLign) in SMILE Pro procedures.
• Assess the impact of intraoperative decentration on refractive outcomes for astigmatism correction.

Strengths

• Includes data from 60 eyes, allowing for a contralateral-eye comparison design within 30 patients.
• Reports specific 6-month follow-up metrics including uncorrected visual acuity, residual cylinder, and vector parameters with p-values.
• Provides detailed preoperative cylinder magnitudes (2.38 ± 0.25 D for high astigmatism, 1.41 ± 0.49 D for moderate-to-low).

Limitations

• Row count is unknown, which may limit suitability assessment.
• The study notes a modest sample size of 30 patients and a narrow high astigmatism range, limiting generalizability.
• Column-level documentation is absent; field semantics must be inferred after download.
