Advanced Surface Ablation (PRK/LASEK)
If you are exploring laser vision correction but have been told you may not be a good candidate for LASIK, PRK eye surgery may be worth considering.
PRK (photorefractive keratectomy) is a proven laser vision correction procedure that uses the same laser technology as LASIK but without creating a corneal flap. For some patients, particularly those with thinner corneas, higher prescriptions, or certain lifestyle considerations, this flap-free approach may be the preferred option.
At CLEI, our experienced refractive surgeons have helped thousands of patients improve their vision through advanced laser eye procedures, including PRK and LASIK. While every patient’s eyes are different, our goal is always the same: helping you find the safest and most effective treatment for your unique vision needs.
If you are considering PRK eye surgery in New Jersey, our team can help determine whether this procedure may be the right fit for you.
What Is PRK Eye Surgery?
PRK eye surgery, also known as photorefractive keratectomy (PRK), is a type of laser vision correction used to reduce dependence on glasses or contact lenses. As the initial laser vision correction method to receive FDA approval, PRK established the foundation for LASIK and the diverse refractive options available today.
Like LASIK, PRK reshapes the cornea, the clear front surface of the eye, using an excimer laser to improve how light focuses on the retina. The goal is clearer vision and less reliance on corrective lenses.
The biggest difference between PRK and LASIK is how the surgeon accesses the cornea.
In LASIK, a thin flap is created and lifted so the laser can reshape tissue beneath the surface. In PRK, the thin outer layer of the cornea (called the epithelium) is gently removed so treatment can be performed directly on the corneal surface. Over the following days, this surface layer naturally regenerates.
Because PRK does not require creation of a corneal flap, more corneal tissue is preserved. For some patients, this makes PRK an excellent alternative to LASIK.
At CLEI, PRK and LASEK (also called advanced surface ablation or ASA) use the same laser technology as LASIK and are performed with the same commitment to precision, safety, and individualized care.
What Does PRK Treat?
PRK can treat several common refractive vision problems, including:
- Nearsightedness (myopia)
- Farsightedness (hyperopia)
- Astigmatism
- Certain vision concerns related to near or reading tasks
During your consultation, your surgeon will evaluate your eyes, prescription, corneal thickness, and overall visual goals to determine whether PRK is likely to provide meaningful improvement.
What Patients are Saying
“I have very complicated eyesight. I’ve had challenges with my eyesight my whole life, and we really needed to find the best. From a consultation standpoint, CLEI is top shelf when it comes to professionalism. They explain everything in detail, but in layman’s terms to help me understand it better. The results have been fantastic. As a contact wearer for my whole life, I no longer have to wear contacts. I can see short-sighted, long-sighted. I don’t even have to wear glasses anymore.” – Phillip
Who Is a Good Candidate for PRK?
PRK is not simply a “backup” option for LASIK. In some cases, it may actually be the preferred procedure. You may be a good candidate for PRK if you:
- Have thinner corneas
- Have a higher glasses or contact lens prescription
- Want a flap-free laser vision correction option
- Have lifestyle or occupational concerns that may increase the chance of eye trauma
- Are looking to reduce dependence on glasses or contact lenses
At CLEI, our goal is to select the laser vision correction procedure that is best suited to each individual patient. The right procedure depends on your eyes, prescription, goals, and daily activities. We perform a detailed evaluation to determine which laser vision correction option is most appropriate for you.
PRK vs. LASIK: What’s the Difference?
PRK and LASIK are very similar procedures in many ways. Both use an excimer laser to reshape the cornea and improve vision, and studies published by our team have shown comparable visual outcomes between LASIK and PRK/LASEK.
The primary distinction between LASIK and PRK is how the surgeon accesses the cornea before laser treatment. LASIK involves creating a thin corneal flap, while PRK gently removes the outer surface layer of the cornea. Once that access is achieved, the laser reshaping performed during both procedures is the same.
Another difference is recovery. LASIK typically offers faster visual recovery and less early discomfort because a corneal flap is created and repositioned. PRK recovery tends to take longer because the surface layer of the cornea must regenerate after treatment.
However, PRK preserves more corneal tissue and avoids flap-related considerations, which may make it a better fit for some patients.
The best procedure depends on the individual. During your consultation, CLEI’s refractive specialists will explain your options and help you understand which treatment may best align with your eyes and goals.
What Happens During the PRK Procedure?
PRK is performed in our in-office laser suite and typically takes about 20 minutes.
During the procedure, numbing eye drops are used to help keep you comfortable. Your surgeon gently removes the thin outer layer of the cornea and then uses an excimer laser to reshape the underlying tissue based on your prescription.
After treatment, a temporary bandage contact lens is placed to help protect the eye while the surface heals.
Although many people are understandably nervous before laser vision correction, the procedure itself is typically quick, and patients are often surprised by how fast it goes.
What Is Recovery Like After PRK?
PRK recovery happens in stages, and understanding what to expect can help reduce anxiety.
The first few days are considered the healing phase. During this time, the surface of the cornea regenerates, and it is normal to experience blurry vision, light sensitivity, tearing, some discomfort, or a gritty sensation. Many patients describe it as feeling like something is in their eye for a few days.
Most people begin feeling more comfortable as healing progresses. At CLEI, PRK procedures are often scheduled on a Thursday to allow patients the weekend to recover before returning to work or daily activities.
Vision recovery is gradual. While many patients can resume driving in about a week, vision may continue fluctuating and sharpening over several weeks as the eyes heal.
Following post-operative instructions carefully is one of the most important parts of recovery. This includes using prescribed drops, avoiding eye rubbing, and protecting the eyes as instructed by your doctor.
How Long Does PRK Last?
PRK permanently changes the shape of the cornea to correct vision.
For most patients, those corneal changes are expected to be long lasting. However, PRK cannot stop normal age-related changes that naturally occur inside the eye.
After age 40, many people experience presbyopia, sometimes called dysfunctional lens syndrome, which makes near vision more difficult. Later in life, cataracts may develop and affect both distance and near vision.
These age-related milestones happen whether or not you have had PRK or LASIK. Fortunately, there are additional treatment options that may help address vision changes later in life.
Is PRK Safe?
PRK has been performed for decades and is considered a safe, well-established form of laser vision correction for appropriate candidates. That said, no vision correction procedure is right for everyone.
The most important factor is choosing the right procedure for the right patient. For some people, LASIK may be the better fit. For others, PRK may offer advantages based on corneal thickness, prescription, or lifestyle.
At CLEI, patient safety begins with a comprehensive evaluation designed to determine candidacy and personalize recommendations.

Frequently Asked Questions About PRK
Does PRK hurt?
Everyone’s recovery experience is different. Some people experience very little discomfort, while others notice a gritty, scratchy sensation, tearing, or light sensitivity during the first few days after surgery.
Most discomfort improves as healing progresses and can often be managed with rest and medications recommended by your doctor.
How long after PRK can I drive?
Many patients can drive within about a week, though timing varies depending on healing and visual recovery. Your surgeon will evaluate your vision during follow-up appointments and let you know when it is safe to resume driving.
Is screen time ok after PRK?
Most people can look at phone, computer, and TV screens as soon as they feel comfortable enough to do so. During the first few days, however, your eyes may be sensitive to light or become tired more easily. Taking breaks and avoiding strain can help during early recovery.
Can you get PRK twice?
In some cases, PRK can be repeated if enhancement is needed. Whether a second procedure is appropriate depends on several individual factors, including corneal health, healing, and visual goals.
Does PRK fix astigmatism?
Yes, PRK can often correct astigmatism. However, results depend on factors such as the type and severity of astigmatism, corneal thickness, and overall eye health. A comprehensive evaluation can help determine candidacy.
How much does PRK cost?
The cost of PRK varies depending on your eyes, prescription, and treatment plan. During your consultation, we will discuss candidacy, options, and pricing so you understand what to expect.
