Laser in situ keratomileusis (LASIK) with an inferior hinge offers a safe and effective alternative for vision correction. This study found significant improvements in refractive outcomes and no loss of best spectacle-corrected visual acuity one month post-procedure.

Area of Science:

  • Ophthalmology
  • Refractive Surgery
  • Corneal Surgery

Background:

  • Laser in situ keratomileusis (LASIK) is a common refractive surgery procedure.
  • The hinge's orientation (superior vs. inferior) may influence outcomes and complications.
  • Investigating alternative hinge designs is crucial for optimizing LASIK safety and efficacy.

Purpose of the Study:

  • To evaluate the refractive results following LASIK using an inferior hinge.
  • To assess corneal pachymetric changes after LASIK with an inferior hinge.
  • To determine the safety and efficacy of the inferior hinge LASIK technique.

Main Methods:

  • Prospective study involving 46 eyes of 23 patients.
  • Comprehensive ophthalmic examinations including visual acuity, refraction, and corneal topography (Orbscan II).

  • Included air-puff tonometry and slit-lamp examinations of the anterior segment and fundus.

    • Main Results:

    • Preoperative mean sphere: -4.09 D, mean cylinder: -0.60 D.
    • One-month postoperative mean sphere: -0.04 D, mean cylinder: -0.01 D.
    • No eyes experienced a loss of best spectacle-corrected visual acuity at one month.

    Conclusions:

    • LASIK with an inferior hinge is a safe and effective alternative surgical technique.
    • Further long-term studies are recommended to compare hinge types regarding corneal ectasia.
    • The inferior hinge approach demonstrates promising refractive and visual outcomes.
