Refractive surgery like LASIK and PRK offers high success rates for vision correction but carries risks. Spectacles remain a safer alternative for most patients, requiring careful consideration before surgery.

Area of Science:

  • Ophthalmology
  • Refractive Surgery

Context:

  • Growing trend of refractive surgery for myopia and astigmatism correction.
  • Limited medical indications for elective refractive surgery procedures.

Purpose:

  • Evaluate the safety and efficacy of modern laser refractive surgery techniques.
  • Compare outcomes of photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK).

Summary:

  • Photorefractive keratectomy (PRK) demonstrates high efficacy (90%+) with low complication rates (<0.5%) for myopia up to -6.0 D.
  • Laser in situ keratomileusis (LASIK) shows similar efficacy for myopia up to -10 D, but with a higher complication rate.
  • Hyperopia correction via laser surgery has comparable success but higher complications and lower patient satisfaction.

Impact:

  • Modern laser surgery can potentially replace spectacles for many refractive errors.
  • No current refractive surgery technique is entirely free of complications.
  • Refractive surgery is considered inferior to spectacles, necessitating comprehensive patient consultation.
