LASIK vs. PRK: Comparative Indications for Refractive Surgery

Both LASIK and PRK correct myopia, hyperopia, and astigmatism via corneal reshaping. Selection criteria:

LASIK Preferred For:

• Thin corneas (PRK risks excessive thinning)
• Dry eye (PRK exacerbates, often prolonged)
• Contact sports (LASIK flap dislocation risk)

PRK Preferred For:

• Large pupils (LASIK increases night glare/halo risk)
• Corneal scarring (PRK avoids flap creation on scarred tissue)

Both are safe and effective; individualized ophthalmologic consultation determines optimal choice.
