[Our fifteen-year experience with LASIK].

Area of Science:

• Ophthalmology
• Refractive Surgery
• Corneal Surgery

Context:

• Laser-Assisted In Situ Keratomileusis (LASIK) is a common refractive surgical procedure.
• Myopia correction remains a significant area of research in ophthalmology.
• Evaluating long-term outcomes is crucial for assessing surgical efficacy and safety.

Purpose:

• To compare long-term LASIK outcomes for myopia correction between different time periods.
• To assess the effectiveness and safety of LASIK surgery for low, middle, and high myopia.
• To analyze the variability and range of refractive outcomes post-LASIK.

Summary:

• A retrospective comparative study evaluated LASIK outcomes in myopia patients from 1999-2010.
• Recent years (2007-2010) showed a 40-50% decrease in outcome variance compared to earlier years (1999-2005).
• Key metrics like Uncorrected Visual Acuity (UCVA) and Best Corrected Visual Acuity (BCVA) demonstrated similar mean values but reduced variability in the later group.

Impact:

• The findings confirm the long-term effectiveness and safety of LASIK for myopia correction.
• Reduced outcome variability suggests improved precision and predictability of the LASIK procedure over time.
• This study provides valuable data for refractive surgeons and patients considering LASIK surgery.
