Photorefractive Keratectomy (PRK) Overview
Photorefractive Keratectomy (PRK) is a laser eye surgery that reshapes the cornea to correct nearsightedness, farsightedness, and astigmatism. Unlike LASIK, PRK removes the corneal surface layer rather than creating a flap, allowing precise vision correction especially for patients with thin corneas or higher injury risk.
How Photorefractive Keratectomy (PRK) Works
PRK uses an excimer laser to remove the outer epithelial layer of the cornea and reshape the underlying tissue to correct refractive errors. The epithelial cells regenerate naturally over several days following the procedure.
- Preparation: Anesthetic eye drops numb the eyes.
- Laser Application: The excimer laser sculpts the cornea with controlled pulses.
- Protection: A soft contact lens is applied to aid healing.
- Recovery: New cells regenerate; vision gradually improves.
Comparison: PRK vs. LASIK
| Feature | PRK | LASIK |
|---|---|---|
| Corneal Flap | No flap — surface epithelium removed | Flap created on cornea |
| Suitability for Thin Corneas | Suitable | Often not recommended |
| Risk of Flap Complications | None | Possible flap complications |
| Recovery Time | Longer (weeks) | Shorter (days) |
| Discomfort Post-Surgery | Higher initially | Lower |
| Risk of Corneal Ectasia | Lower | Higher |
