PRK (Photorefractive Keratectomy) in the Bay Area – A Flap-Free Alternative to LASIK
PRK, or photorefractive keratectomy, was the first laser vision correction procedure developed and remains a reliable option today. Unlike LASIK, PRK is a surface-based treatment, meaning no corneal flap is created.
Because of this, PRK is often recommended for patients with:
- Thinner corneas
- Irregular or scarred corneal surfaces
- Situations where preserving corneal strength is important
What Is PRK and How Does It Work?
PRK reshapes the cornea to improve how light is focused onto the retina. It is used to treat:
- Nearsightedness (myopia)
- Farsightedness (hyperopia)
- Astigmatism
During the procedure, the outer layer of the cornea (epithelium) is removed, and a computer-guided laser is used to perform the correction.
What to Expect During the Procedure
PRK is performed in-office and takes only a few minutes per eye.
- Numbing eye drops are applied
- The surface layer of the cornea is gently removed
- The excimer laser reshapes the cornea based on your measurements
The laser portion itself is typically completed within seconds to a couple of minutes.
Recovery and Visual Improvement
Most patients:
- Go home the same day
- Notice vision improvement by the next day
- Experience a relatively quick recovery
Your doctor will provide specific post-operative instructions to support healing and optimize results.
PRK vs LASIK – Which One Is Better?
This is one of the most common questions patients ask:
“Should I choose PRK or LASIK?”
Both procedures use the same laser technology to correct vision. The main difference is how the cornea is accessed.
LASIK
- A thin flap is created in the cornea
- Faster visual recovery (often next day)
- Minimal discomfort after surgery
- Not ideal for patients with thin corneas
PRK
- No flap is created (surface treatment)
- Preserves more corneal tissue
- Safer for thin or irregular corneas
- Longer recovery (several days to a few weeks)
In terms of final visual outcome, PRK and LASIK are comparable. The decision is less about “which is better” and more about which is safer and more appropriate for your eye structure.
Why Some Patients Are Better Suited for PRK
PRK is often recommended when:
- Corneal thickness is borderline for LASIK
- There is concern about flap-related complications
- The patient has a more active lifestyle where eye trauma is a consideration
Because PRK does not involve creating a flap, the cornea remains structurally stronger long-term.
A Proven Option for Long-Term Vision Correction
PRK has been performed for decades and continues to deliver stable, predictable results. While recovery takes longer than LASIK, it remains an excellent option for patients who are not ideal LASIK candidates.
