Photorefractive keratectomy (PRK) is a type of corrective eye surgery used to improve vision by reshaping the cornea with a laser. Unlike LASIK, PRK does not involve creating a corneal flap, making it a preferred choice for individuals with thinner corneas or active lifestyles.
PRK has been used safely for decades and continues to be enhanced with modern technologies to deliver clear, long-lasting results.
How does PRK work? The procedure uses an excimer laser to reshape the surface of the cornea after the outermost layer (epithelium) is gently removed. This allows light to properly focus onto the retina for clearer vision.
Step-by-step process:
The PRK healing process begins immediately, with vision gradually improving over days to weeks.
PRK can effectively treat multiple vision conditions caused by refractive errors. These include:
The goal of PRK vision correction is to allow your eye to focus light correctly onto the retina, reducing or eliminating the need for corrective eyewear.
Proper preparation ensures a smooth surgical experience and faster recovery.
Before the procedure:
Patients should also have realistic expectations and understand the PRK recovery time, which may take several weeks for full visual clarity.
The PRK procedure is straightforward and typically completed within 10–15 minutes per eye.
Procedure outline:
While the surface takes time to heal, patients often begin to notice improved vision within the first few days after surgery. What PRK eye surgery is becomes clear with this flapless, safe technique.
Recovery after PRK requires patience and attention to your doctor's instructions.
Post-operative care includes:
The initial discomfort and blurriness improve as the epithelium regenerates. Understanding PRK side effects like temporary dryness and light sensitivity helps manage expectations.
PRK offers unique advantages, especially for patients who are not ideal candidates for LASIK.
Benefits include:
When evaluating PRK vs. LASIK, consider your corneal health, lifestyle, and long-term visual goals.
PRK is ideal for:
A consultation will determine your eligibility based on eye health, lifestyle, and vision needs. PRK corrective eye surgery is often recommended when LASIK isn’t advisable.
As with any surgery, PRK has potential risks, though they are rare and usually manageable.
Possible side effects include:
Most PRK side effects resolve with time and appropriate care. Your surgeon will address all concerns during the consultation.
Understanding the PRK recovery time is important for planning your return to normal activities.

What to Expect:
The complete PRK healing process varies by individual but is typically very successful long-term.

Why patients choose Dr. Feldman:
For expert PRK long-term results, choose a center committed to excellence and safety.
Q1. What are the expected results after PRK?
Ans: Most patients achieve 20/20 vision or better within 1–3 months after surgery. Visual clarity improves gradually, and final results depend on the refractive error treated.
Q2. How long does the PRK procedure take?
Ans: The procedure typically takes 10 to 15 minutes per eye. The entire appointment, including prep and post-care instructions, usually lasts about 1.5 to 2 hours.
Q3. How can I schedule a consultation for PRK/ASA?
Ans: You can schedule a consultation by contacting the center directly through their website or phone. A thorough exam will determine your eligibility for PRK/ASA.
Q4. Is PRK more permanent than LASIK?
Ans: Both procedures offer long-lasting results. PRK is often considered more stable over time for certain eye types, especially those with thinner corneas or high prescriptions.
Q5. Can I wear contacts before my consultation for PRK/ASA?
Ans: You should stop wearing soft contact lenses at least 5–7 days before your consultation. Rigid lenses may require longer discontinuation to allow accurate eye measurements.
Q6. How often should I follow up after my PRK surgery?
Ans: Follow-up visits are typically scheduled for the next day, one week, and several intervals over the first few months to monitor healing and vision improvement.
