Your experience begins with the application of anesthetic eye drops to ensure you feel no pain throughout the surgery.
An instrument is used to gently hold your eyelid open while you focus on a target light. This allows our refractive eye surgeon to work precisely on your cornea.
The surgeon delicately removes the outer layer of the cornea, known as the epithelium. This layer, which is as thin as a human hair, is necessary to be removed in order to access the stroma, where reshaping will occur.
An excimer laser then delivers controlled pulses of cool ultraviolet light; these precise bursts remove minuscule amounts of tissue from the cornea to achieve the proper curvature required for clear vision. The adjustments can be made with extreme accuracy, down to one-thousandth of a millimeter.
After the reshaping process, a protective bandage contact lens is placed over your eye. This lens helps shield the cornea as the epithelial cells begin to regenerate over the next few days.
Each of these steps is designed to maximize safety and precision, so you know you’re in good hands throughout your PRK treatment.
You may feel a slight pressure during the procedure, but thanks to the numbing drops, any discomfort is minimal. The entire process for each eye typically takes between five and fifteen minutes.
This laser is a remarkably precise tool that targets only the specific areas of your cornea requiring reshaping, without affecting surrounding tissues. This precision contributes to the overall safety and effectiveness of PRK.
Since the procedure is done with the aid of anesthetic drops, it is described as generally painless. Most patients are astounded by how smooth and controlled the process is.
Your experience during the procedure is carefully managed to ensure that you remain comfortable and secure, reinforcing the trust you place in our refractive eye surgeon.
Once the excimer laser has completed its work, a bandage contact lens is placed on your eye. This protective covering helps reduce discomfort while your corneal epithelial cells regrow. Typically, the lens is removed after three to five days, once enough new tissue has formed.
As the epithelium heals, you might experience mild to moderate discomfort that resembles having a foreign object in your eye. Common experiences include tearing, light sensitivity, and a transient blurring of vision. These symptoms usually peak around the second or third day after surgery.
In the days following the surgery, you may notice gradual changes in your vision. For many patients, the initial clarity ranges from 20/30 to 20/50, depending on the extent of the treatment. As the new epithelial layer continues to smooth out, which takes about four to six weeks, your vision will steadily improve.
Though it may take several weeks for you to notice the full benefits, your vision is typically considered stable by three to six months after PRK. If necessary, our refractive eye surgeon may discuss a secondary procedure to adjust and enhance your outcome.
The recovery period after PRK is a gradual process, and while patience is required, the long-term results are well worth the brief period of healing and adjustment.
PRK avoids creating a flap, which means the outer layer of your cornea is removed rather than being lifted and repositioned. This eliminates risks that can be associated with flap-related complications such as its dislocation after trauma.
For patients with thinner corneas or irregular corneal shapes, PRK offers a safer alternative since more of the corneal structure remains intact after surgery.
Since the procedure does not involve cutting through as many nerves as LASIK does, there tends to be a more rapid recovery of normal corneal nerve function, which in turn minimizes issues with dry eye symptoms.
Those who work or participate in sports where eye trauma is a possibility may find PRK a more secure option since there is no flap to be dislodged in the event of an impact.
LASIK involves the use of a microkeratome or a laser to create a corneal flap. Once the flap is lifted, the excimer laser reshapes the underlying tissue, after which the flap is replaced, helping to protect the cornea as it heals.
Patients undergoing LASIK often experience a faster initial recovery, with many noticing improved vision within a day.
Although rare, issues such as a dislodged or elevated flap can occur, especially if the eye sustains trauma after surgery.
Choosing between PRK and LASIK depends largely on your eye’s health, corneal thickness, and lifestyle considerations. Our refractive eye surgeon takes careful measurements and evaluates your vision needs during a comprehensive exam to determine the procedure that is best suited to you.
Since there is no flap creation, your cornea remains structurally stronger. This can be critical for patients with thinner corneas or those engaged in activities where sustaining an eye injury is a concern.
PRK not only improves your vision immediately after healing, but it also provides lasting results. After your vision stabilizes, many patients enjoy years of clear sight without the need for corrective eyewear.
If you suffer from chronic dry eyes or have a corneal shape that may not support a flap, PRK presents a well-suited alternative where these issues are less of a concern.
For those whose jobs or hobbies expose them to potential eye trauma, PRK reduces the risk of complications that could be associated with flap-related procedures.
Advanced approaches, such as wavefront-guided PRK, allow for a highly personalized treatment that maps and corrects subtle imperfections, aiming for vision that is closer to 20/20 or even better.
These benefits help explain why PRK is still chosen by many, even in an era where flap-based procedures like LASIK are more common. If your eye exam determines that you are a strong candidate for PRK, you can look forward to a lasting enhancement in your quality of vision.
Our refractive eye surgeon uses advanced wavefront technology to create a three-dimensional map of your eye’s optical imperfections. This personalized map highlights subtle issues that standard measurements might miss.
With this level of detail, the laser treatment is adjusted to address unique visual distortions and irregularities. This method can lead to results that come remarkably close to perfect vision, frequently approaching 20/20 clarity.
Apart from the enhanced mapping, the overall procedure remains similar to that of standard PRK. After the mapping is complete, the steps of numbing the eye, removing the epithelium, reshaping the cornea, and protecting it with a bandage contact lens follow as usual.
This wavefront-guided method offers patients an extra level of confidence knowing that the treatment is custom-tailored to the intricate details of their eyes. It can be particularly beneficial for those with complex refractive errors or subtle visual distortions.
You should be at least 21 years old with a stable refractive prescription for at least two years. Stability is key for long-lasting results.

PRK is effective in treating various refractive errors. It is designed to correct nearsightedness up to -12.00 diopters, farsightedness up to +6.00 diopters, and astigmatism up to 6.00 diopters.
Your cornea should be free of abnormal conditions such as significant scarring, infections, or atypical thinning. This ensures that the corneal reshaping will result in a smooth and effective outcome.
PRK is particularly suitable for those with chronic dry eyes or thinning corneas that might not be ideal for flap-based procedures. In addition, individuals whose lifestyles or professions involve a higher risk for eye trauma may find PRK a favorable option.
It is important to note that if you have a history of autoimmune diseases, corneal dystrophies, past viral infections like herpes, advanced glaucoma, or uncontrolled diabetes, PRK might not be the ideal procedure for you. Our refractive eye surgeon will carefully review your medical history and perform detailed examinations to determine the safest and most effective approach for your vision correction.
Your consultation will begin with a detailed eye examination. We will measure the curvature of your eye, check your corneal thickness, evaluate tear production, and assess the stability of your refractive error. This precise evaluation is vital for customizing your treatment plan.
If you wear contact lenses, you will be advised to stop using them for a period—typically at least two weeks—prior to your exam. This ensures that your corneas are in their natural state for the most accurate measurements.
It’s an excellent time to ask questions. Our refractive eye surgeon will clarify every step of the PRK process, review what to expect in terms of discomfort, recovery, and long-term outcomes, and discuss any lifestyle considerations you should be aware of during the healing phase.
These preparatory steps help establish a strong foundation for a successful surgery and ensure that you are fully informed and comfortable with the process.
In most cases, patients begin to notice significant vision improvement within the first few days. However, since the corneal epithelium is healing and reshaping, the vision may be somewhat variable during the early days post-surgery.
Over the course of four to six weeks, the healing tissue smooths out, and your vision continues to improve. You might experience minor fluctuations as the healing process completes.
Most patients reach a stable end point within three to six months after surgery. At this time, if additional adjustments are needed, our refractive eye surgeon can discuss enhancement procedures to fine-tune your vision even further.
While the healing process after PRK may seem gradual compared to other refractive surgeries, the carefully managed recovery period ensures lasting benefits. Many patients appreciate the long-term stability that comes with a procedure specifically suited for their corneal structure.
The PRK surgery itself typically lasts between five and fifteen minutes per eye. The entire process, including preparation and recovery room time, usually does not require extended time in our facility.
Thanks to the use of anesthetic eye drops, most patients report that the procedure is painless. While some describe a slight sensation of pressure, any discomfort is well managed with medications and is temporary.
Recovery from PRK takes a bit longer than flap-based procedures. Many patients experience initial discomfort for a few days, with gradual visual improvements observed over several weeks. Full visual stabilization typically occurs within three to six months.
Directly after the procedure, a bandage contact lens protects your eye as the epithelium regrows. You may notice tearing, sensitivity to light, and some blurring. However, these effects generally lessen significantly within the first week.
Yes. In fact, PRK is often chosen specifically because it avoids creating a flap, a factor that can contribute to dry eye symptoms in other procedures.
If your vision requires further adjustment, enhancement procedures can be performed. Although these additional steps are rarely needed, they follow essentially the same process as the original surgery.
These FAQs reflect the key areas of concern for many patients and highlight the thoughtful approach our refractive eye surgeon takes to ensure that you have all the information necessary to make an informed decision regarding PRK.
You will be prescribed specific eye drops—often including lubricating and medicated solutions—to reduce discomfort, minimize the risk of scar formation, and prevent infections during the healing process. In some cases, cortisone drops may be used for several months to diminish the potential development of any noticeable haze.
Follow-up visits in the days after surgery are critical to monitor healing progress. These visits allow our refractive eye surgeon to check that the corneal epithelium is regrowing properly and that no complications have developed.
During the early recovery period, you may need to avoid strenuous activities, swimming, or exposure to dusty or smoky environments. This careful management of your environment helps promote optimal healing and clear vision.
Staying engaged with your post-operative care routine ensures that you get the best long-term outcome from your PRK surgery. Our refractive eye surgeon is always available to answer your questions and provide personalized advice tailored to your recovery progress.
Deciding on a vision correction procedure is a significant decision that involves careful consideration of your lifestyle, eye health, and personal preferences. Many patients choose PRK because it offers a reliable, long-term solution without the need for a corneal flap, making it especially appropriate for those with thinner corneas or active lifestyles prone to eye trauma.
During your initial consultation, our refractive eye surgeon performs a detailed evaluation including corneal mapping and refractive error measurements to determine if PRK is the most appropriate treatment for you. Beyond the technical aspects, we take time to listen to your concerns, discuss your lifestyle needs, and ensure your expectations align with what the procedure can realistically achieve.
