Excimer laser in situ keratomileusis (LASIK) is a safe and effective treatment for high and moderate hyperopia. Further algorithm adjustments are needed to prevent undercorrection in refractive surgery.

Area of Science:

  • Ophthalmology
  • Refractive Surgery
  • Laser Vision Correction

Context:

  • Hyperopia, a refractive error, can be treated with surgical interventions.
  • Excimer laser in situ keratomileusis (LASIK) is a popular refractive surgery technique.
  • High and moderate hyperopia present unique challenges for surgical correction.

Purpose:

  • To assess the safety and efficacy of excimer laser LASIK for correcting high and moderate hyperopia.
  • To evaluate visual outcomes and complications associated with this procedure.

Summary:

  • LASIK was performed on 17 eyes (9 patients) with spherical equivalents ranging from +5.50 to +9.00 D.
  • No serious complications occurred; no eye lost best-corrected visual acuity lines.
  • At 12 months, mean spherical equivalent was +1.77 D, with 52.9% achieving 0 to +1.00 D correction.

Impact:

  • LASIK demonstrates safety and effectiveness for treating significant hyperopic refractive errors.
  • Results suggest the need for algorithm refinement to optimize refractive outcomes and minimize undercorrection.
  • This study contributes to understanding LASIK's role in managing complex hyperopia.
