Clinical Outcomes of Preservative-Free Diclofenac in SPT-Assisted TransPRK Surgery

239 patient records from a retrospective cohort study comparing postoperative pain and epithelial recovery after SPT-assisted TransPRK surgery between January 2022 and December 2025. The dataset, authored by Huang Zhang and last updated in April 2026, contains clinical outcomes for patients treated with either pranoprofen or preservative-free diclofenac sodium eye drops. Results include visual analog scale pain scores at multiple time points, time to epithelialization, and bandage contact lens removal times.

Use Cases

• Compare postoperative pain scores based on visual analog scale measurements mentioned in the description
• Analyze time to complete epithelialization and bandage contact lens removal between treatment groups
• Assess the proportion of patients achieving mild pain (VAS ≤ 3) at 24 hours post-surgery
• Evaluate corneal haze grading and adverse event rates for short-term safety comparisons

Strengths

• Includes results for 239 patients with a clear control (n=118) and observation (n=121) group structure
• Contains specific statistical comparisons (P-values) for pain scores and recovery times
• Data covers a defined time range from January 2022 to December 2025

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect temporal bias inherent to the single retrospective study design
