Summary

Many patients seeking refractive surgery like LASIK or PRK are ineligible due to high refractive errors, insufficient corneal thickness, or conditions like keratoconus. Careful patient evaluation is crucial for successful outcomes.

Area of Science:

  • Ophthalmology
  • Refractive Surgery
  • Corneal Surgery

Background:

  • Refractive surgery aims to correct vision errors like myopia and astigmatism.
  • Laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) are common procedures.
  • Patient selection is critical for successful refractive surgery outcomes.

Purpose of the Study:

  • To identify and analyze the reasons why patients seeking refractive error correction were not candidates for LASIK or PRK.
  • To understand the prevalence of contraindications for laser vision correction.

Main Methods:

  • Retrospective review of 2784 patients requesting refractive surgery at a single eye clinic.
  • Analysis of patient records to determine reasons for exclusion from PRK or LASIK procedures.

Main Results:

  • 74.7% of patients were suitable for PRK or LASIK, while 25.3% were not.
  • Leading reasons for exclusion included high myopia/astigmatism (> -12.0D) (20.7%), insufficient corneal thickness (8.2%), and keratoconus (6.4%).
  • Other exclusion factors were cataracts (5.7%) and hyperopia/hyperopic astigmatism (4.1%).

Conclusions:

  • A significant portion of patients seeking refractive surgery have conditions that preclude them from undergoing LASIK or PRK.
  • Individual patient assessment and careful consideration of surgical indications are essential.
  • Understanding contraindications improves patient selection and surgical outcomes in refractive error correction.
