When it comes to vision correction, LASIK is often the most talked-about procedure. However, not everyone is a suitable candidate for it. If you have thin corneas, dry eyes, or other eye conditions that make LASIK risky, you might be wondering: What Is PRK Eye Surgery, and is it a better alternative?
In this blog, we’ll explain how PRK works, how it compares to LASIK, and who can benefit the most from this procedure.
What Is PRK Eye Surgery?
What Is PRK Eye Surgery? PRK (Photorefractive Keratectomy) is a laser vision correction procedure designed to reshape the cornea and correct refractive errors like nearsightedness, farsightedness, and astigmatism. Unlike LASIK, PRK does not involve creating a corneal flap. Instead, the outermost layer of the cornea (epithelium) is gently removed before reshaping the corneal tissue with a laser.
This makes PRK an excellent choice for individuals with thin corneas or those at higher risk of complications from LASIK.
PRK vs. LASIK: Which One Is Better?
Both PRK and LASIK offer excellent vision correction results, but they differ in terms of procedure, recovery, and suitability.
1. Surgical Method
- PRK: The epithelium is completely removed before using a laser to reshape the cornea. The epithelium naturally regenerates over a few days.
- LASIK: A thin flap is created on the cornea, which is lifted to reshape the underlying tissue and then repositioned.
2. Recovery Time
- PRK: Recovery takes longer (about 1-2 weeks for clear vision) because the epithelium needs to regrow. Patients may experience discomfort during healing.
- LASIK: Recovery is much quicker (24-48 hours) with minimal discomfort since the corneal flap remains in place.
3. Long-Term Results
- PRK: Since there’s no flap, the risk of flap-related complications is eliminated. PRK provides equally long-lasting vision correction as LASIK.
- LASIK: Provides rapid results but carries a slight risk of flap dislocation due to trauma.
4. Best Candidates
- PRK: Recommended for people with thin corneas, dry eyes, or those with active lifestyles (such as athletes or military personnel) who risk corneal flap injuries.
- LASIK: Suitable for most people with moderate refractive errors and healthy corneas.
Advantages of PRK Eye Surgery
✔ Safe for Thin Corneas – A great option for patients who are ineligible for LASIK due to corneal thickness.
✔ No Risk of Flap Complications – Eliminates the possibility of flap dislocation or infection.
✔ Effective for High Refractive Errors – Can correct moderate to severe nearsightedness, farsightedness, and astigmatism.
✔ Permanent Results – Once the eyes heal, vision improvement is stable and long-lasting.
✔ Less Risk of Dry Eyes – Since no corneal flap is created, PRK reduces the chances of post-surgery dry eyes.
Who Should Consider PRK?
You may be a good candidate for PRK if:
✅ You have thin or irregular corneas
✅ You have chronic dry eye syndrome
✅ You lead an active lifestyle with a risk of eye trauma
✅ You want a long-term vision correction solution
While the initial healing process for PRK takes longer than LASIK, many patients find the benefits well worth the wait.
