Laser in situ keratomileusis (LASIK) for hyperopia shows promising results with less regression and improved stability compared to photorefractive keratectomy. Preoperative corneal radius is a key factor for high hyperopia outcomes.

Area of Science:

  • Ophthalmology
  • Refractive Surgery

Background:

  • Hyperopic LASIK is an established procedure for correcting farsightedness.
  • Evaluating the efficacy and safety of LASIK for hyperopia is crucial for patient outcomes.

Purpose of the Study:

  • To assess the initial outcomes of laser in situ keratomileusis (LASIK) for hyperopia.
  • To compare LASIK for hyperopia with surface photorefractive keratectomy.

Main Methods:

  • Retrospective evaluation of 43 eyes undergoing hyperopic LASIK.
  • Patients divided into two groups based on refractive error (+1.00 to +4.00 D and +4.25 to +8.00 D).
  • Objective refraction and visual acuity measured over 12 months post-surgery.

Main Results:

  • One-year post-LASIK, mean spherical equivalents were +0.33 D (Group 1) and +1.91 D (Group 2).

  • Best corrected visual acuity remained stable in 35% (Group 1) and 57% (Group 2).
  • A small percentage of patients experienced a loss of best corrected visual acuity.

    • Conclusions:

    • LASIK for hyperopia demonstrated reduced regression, minimal haze, and enhanced predictability and stability compared to PRK.
    • Preoperative corneal radius was identified as a significant factor influencing outcomes in high hyperopia cases.
