To compare refractive predictability, long-term stability, visual quality, ocular surface outcomes, and safety of SMILE, FS-LASIK, and Trans-PRK for myopia correction in an Iraqi population over a specified time frame.
Key Findings:
SMILE showed the highest refractive predictability and long-term stability, with specific data points to be included.
FS-LASIK had intermediate outcomes, while Trans-PRK had greater residual myopia and increased refractive regression.
Induced corneal HOAs were lowest after SMILE and highest after Trans-PRK.
OSDI scores were lowest after SMILE, intermediate after FS-LASIK, and highest after Trans-PRK.
Surgical technique was the primary predictor of residual SE at 1.5 years.
Interpretation:
SMILE is superior in refractive predictability, stability, visual quality, and ocular surface outcomes compared to FS-LASIK and Trans-PRK, suggesting the need for procedure-specific patient selection to optimize outcomes.
Limitations:
Retrospective design may introduce selection bias; further context on its impact on results is needed.
Long-term follow-up beyond 1.5 years is needed for comprehensive assessment.
Conclusion:
SMILE is the preferred method for myopia correction in this cohort, while FS-LASIK remains effective and safe. Trans-PRK is less favorable due to greater refractive regression and higher enhancement rates, highlighting the importance of these findings in the context of global myopia trends.
