Summary

Laser vision correction using LASIK is safe and effective for myopia treatment. Results show good predictability, especially for moderate myopia, with potential for improvement through additional procedures.

Area of Science:

  • Ophthalmology
  • Refractive Surgery

Background:

  • Myopia, or nearsightedness, affects a significant portion of the population.
  • Laser-Assisted In Situ Keratomileusis (LASIK) is a common surgical procedure for vision correction.

Purpose of the Study:

  • To evaluate the long-term outcomes of LASIK surgery for myopia treatment.
  • To assess the safety, effectiveness, and predictability of LASIK across different degrees of myopia.

Main Methods:

  • A retrospective analysis of 4170 eyes from 3163 patients who underwent LASIK for myopia.
  • Patients were categorized into three groups based on preoperative spherical equivalent: -5 to -10D (Group A), -10 to -16D (Group B), and over -16D (Group C).

Main Results:

  • One year post-surgery, 84.4% of eyes in Group A, 70.8% in Group B, and 42.8% in Group C achieved visual outcomes within +/- 1D of emmetropia.
  • The study analyzed outcomes over a seven-year period.

Conclusions:

  • LASIK is a safe, effective, and predictable treatment for myopia, particularly for refractive errors between -5D and -15D.
  • Enhancements or secondary procedures can further improve refractive outcomes and predictability.
