Photorefractive Keratectomy (PRK) and Vision Correction
How PRK Works
This section explains the step-by-step process used during PRK so you know what happens to your eye during surgery.
Anesthetic eye drops are applied so you feel no pain during the procedure.
A small instrument holds the eyelid open while you look at a target light, allowing precise work on the cornea.
The surgeon gently removes the thin outer layer of the cornea to reach the stroma, where reshaping occurs.
An excimer laser delivers cool ultraviolet light to remove tiny amounts of tissue, creating a new corneal curvature with accuracy down to a thousandth of a millimeter.
A protective lens is placed on the eye to shield it while the epithelium regenerates over the next few days.
What to Expect During the Procedure
Knowing how the surgery feels and how the laser works can help you feel calm and prepared.
You may notice slight pressure, but discomfort is minimal thanks to numbing drops. Each eye usually takes five to fifteen minutes.
The laser targets only the areas needing correction, leaving surrounding tissue untouched for greater safety.
Most patients describe the process as painless and are surprised by how controlled it feels.
Who Is a Candidate for PRK
Certain eye and health factors determine whether PRK is right for you.
Candidates should be at least 21 years old with a stable prescription for two years to ensure long-lasting results.
PRK can correct nearsightedness up to ‑12.00 diopters, farsightedness up to +6.00 diopters, and astigmatism up to 6.00 diopters.
The cornea must be free of significant scarring, infection, or thinning to allow a smooth outcome.
PRK suits people with chronic dry eyes, thin corneas, or lifestyles that carry a higher risk of eye injury. It may not be recommended for those with certain autoimmune diseases, advanced glaucoma, or uncontrolled diabetes.
Preparing for Your PRK Procedure
Proper preparation leads to accurate measurements and a smoother recovery.
We measure corneal thickness, curvature, tear production, and prescription stability to create a personalized plan.
You will stop wearing contact lenses for about two weeks before the exam so your corneas return to their natural shape.
The surgeon reviews each step, explains possible sensations, and answers questions about recovery and long-term results.
Recovery and Long-Term Results
Healing after PRK is gradual, but the vision gains are designed to last.
Vision often improves within days, though it can fluctuate as the epithelium heals.
Over four to six weeks, the healing tissue smooths out and vision continues to sharpen.
Most patients reach stable vision in three to six months, and enhancements can be discussed if needed.
Benefits of PRK
PRK offers several advantages that make it a preferred option for many patients.
Without a corneal flap, the eye maintains more structural strength, which is helpful for thin corneas.
Once vision stabilizes, many people enjoy clear sight for years without corrective lenses.
PRK is often chosen by those with chronic dry eyes or corneal shapes that do not suit flap-based surgeries.
Patients with jobs or hobbies that involve eye impact risk face fewer flap-related complications.
Wavefront-guided techniques allow the laser to correct subtle imperfections for sharper vision.
Frequently Asked Questions
The questions below address common concerns patients share about PRK.
Surgery usually lasts five to fifteen minutes per eye, and total time in the office is brief.
Anesthetic drops prevent pain, and any mild pressure is temporary.
Initial discomfort lasts a few days, vision improves over weeks, and full stability occurs within three to six months.
A bandage contact lens protects the eye while the epithelium regrows. Tearing, light sensitivity, and blurring typically ease within a week.
Yes. PRK often avoids worsening dry eye symptoms because no flap is created.
If needed, an enhancement procedure can fine-tune your vision after healing is complete.

Dr. Ahmed Nasrullah is excellent! His bedside manner is second to none, and just one day after LASIK I’m already seeing 20/20. Highly recommend him for LASIK.
Darrell Kent
I had LASIK on both eyes, and the experience was amazing. I now see without glasses. Dr. Nasrullah explained everything and used advanced precise equipment "the Ferrari of Lasik machines".
Elliott Root
One of the best optometrists! Knowledgeable, kind, and reassuring. If you're nervous about LASIK, he makes you feel safe and comfortable. The whole process was smooth—I’d 100% recommend him!
Miguel Manzo
I had a wonderful experience getting LASIK! By the next morning, I was seeing 20/20. The doctor was kind and efficient, and the office made everything stress-free. Very happy with the results.
