PRK Eye Surgery: Clear Vision, No Flap

What Is PRK?

Photorefractive Keratectomy (PRK) is a safe, proven laser eye surgery that corrects nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. Unlike LASIK, PRK does not create a corneal flap —making it an excellent choice for patients with thin corneas, dry eyes, or active lifestyles.

Who Is a Good Candidate for PRK?

  •  Age 18+ with stable vision for at least 1 year
  •  Healthy eyes with no infections, scars, or severe dry eye
  •  Corneas too thin for LASIK, or you prefer a flapless procedure
  •  Realistic expectations about results and recovery
  •  Not pregnant or nursing (hormones can affect vision stability)
  • Sensitivity to light (photophobia)

Note: If you wear contact lenses, stop wearing soft lenses 3+ days (rigid lenses: 3+ weeks) before your evaluation.

The PRK Procedure: Simple & Painless

  • Total time: ~10 minutes per eye
  • Anesthesia: Numbing eye drops only—no needles
  • Comfort: Mild sedative available; you stay awake and relaxed

How PRK Works

PRK uses a cool, computer-controlled excimer laser to gently reshape the cornea—the clear front surface of your eye—so light focuses correctly on the retina. Vision Issue What Happens How PRK Fixes It Nearsightedness Eyeball is too long light focuses in front of retina Laser flattens the center of the cornea Farsightedness Eyeball is too short light focuses behind retina Laser steepens the cornea's outer edge. Astigmatism Cornea is football-shaped light splits into two focus points Laser smooths the cornea into a more spherical shape

light focuses  behind  retina   Laser steepens the cornea’s outer edge.

Astigmatism

Cornea is football-shaped
