For many patients, the dream of clear vision without the hassle of glasses or contact lenses may be a reality thanks to advancements in vision correction procedures like photorefractive keratectomy (more commonly known as PRK or PRK LASIK).

Photorefractive keratectomy, or PRK, is a safe and effective alternative to LASIK surgery, for those who don’t qualify as candidates for LASIK. However, as with any medical procedure, there are things to consider when deciding if PRK eye surgery is right for you.

The ophthalmologists at Eye Center of Texas are here to shed light on the PRK eye surgery pros and cons, what to expect during the surgery and recovery, and who might and might not be an ideal candidate. We’re hoping that this will help you to make an informed choice for your ocular health.

What is PRK surgery?

Photorefractive keratectomy (PRK) is a type of refractive surgery that can correct common vision problems such as mild to moderate nearsightedness, farsightedness, and astigmatism. The PRK procedure itself is fairly short, lasting only around 15 minutes long. The surgery reshapes the cornea, the clear front part of the eye, so that light is focused properly onto the retina.

The difference between PRK and LASIK is that unlike LASIK, which creates a flap in the cornea, PRK gently removes the outer layer of the cornea before reshaping it with an ultraviolet beam of light. Once the cornea is reshaped, a “bandage” contact lens is placed over the eye to help protect the surface as it heals. The top layer of the cornea eventually grows back over the reshaped internal layers.

Want to know if PRK eye surgery is the best vision correction procedure for you? Let’s discuss the PRK eye surgery pros and cons.

What are the advantages of photorefractive keratectomy?

Here is a list of reasons why getting PRK may be beneficial for you and your vision.

1. PRK is typically safer than LASIK

Is PRK surgery safe? Yes! Since PRK does not leave a flap in your cornea like LASIK does, you are less likely to deal with complications such as flap displacement, wrinkling, or unexpected growth.

PRK is seen as safer for patients who have:

• Dry eye condition
• Active lifestyle preferences
• High corrective prescription (meaning you are more farsighted)
• Thin corneas

How safe is photorefractive keratectomy?

While every medical procedure has its risks, such as infection or miscorrection, PRK is considered a low-risk procedure when performed by a skilled eye surgeon. Because PRK does not require anesthesia, many patients worry about pain, but there’s no need to be anxious. Your ophthalmologist will use numbing drops in your eyes before the procedure and offer an oral sedative if you feel you need it. Many patients note that PRK is quick and painless.

2. More patients qualify for PRK

A big reason that not many people qualify for LASIK is that their corneas are too thin or they deal with dry eye syndrome as stated above. However, patients with thin corneas or corneal irregularities that may complicate the flap creation from LASIK could benefit from PRK instead.

Additionally, PRK can be a suitable option for people with certain professions or hobbies that may involve contact sports or other activities where contact with the eyes is possible.

How do I know if I qualify for PRK? Here is a list of indicators that you would be an ideal candidate for PRK:

• You’re at least 18 years old
• You experience refractive errors (myopia, hyperopia, astigmatism)
• You’re not pregnant or nursing
• You’ve had a stable prescription for at least one year
• You haven’t experienced eye injuries or infection within the last year
• You’re not suffering from dry eye syndrome
• You have no issues with keratoconus

Who is a bad candidate for PRK?

Certain health and lifestyle factors could make PRK a less-than-ideal choice for vision correction surgery. Candidates who do not qualify for PRK may include:

• People with an unstable prescription
• People with a history of corneal diseases
• People with systemic health conditions (especially those affecting the immune system)
• Individuals with unrealistic expectations about the results and recovery process

3. Fewer risks and side effects

PRK has fewer and less severe side effects than a surgery like LASIK. For example, you won’t run the risk of getting dry eye syndrome from disrupted nerves. However, every vision correction surgery will come with its own set of side effects to be aware of.

Common PRK side effects to keep an eye out for in the first week of recovery include:

• Mild to moderate discomfort or itching
• Light sensitivity
• Seeing bursts or halos of light for the first few weeks
• Cloudy or hazy vision (corneal haze)

4. High success rate

The PRK success rate is very high, making it a popular choice among patients. According to the FDA, about 95% of PRK patients achieve 20/40 vision without the need for corrective lenses or glasses after one-year post-op. This means that many patients can throw out their glasses or contacts within a year of getting PRK.

5. Long-term results

During the initial healing phase, the outer layer of the cornea regenerates, leading many ophthalmologists to believe that PRK offers a more stable and long-term outcome compared to LASIK. The gradual healing process also means that the vision may take longer to fully stabilize, but the results are often more predictable.

What are the cons of PRK surgery?

While photorefractive keratectomy may come with many benefits, it also is accompanied by a short list of things that all patients should consider before committing to PRK.

1. Longer recovery time

PRK recovery is a little longer than LASIK due to the nature of the surgery. Where the corneal flap can simply be realigned after LASIK, the outer layer that was scraped away during PRK needs time to grow back. Patients can expect to be fully recovered within 2-4 weeks of getting PRK, but recovery time may depend on the individual patient’s circumstances.

2. Discomfort and sensitivity

Due to the removal of the protective outer layer of the cornea during PRK, the initial days following the procedure can bring a little more discomfort than LASIK or other surgeries. Patients often experience some mild pain, light sensitivity, or hazy vision which generally subsides within a few days as the cornea begins to regenerate. Make sure to not do any strenuous exercise or activities while you’re in recovery.

3. Possibility of vision overcorrection or undercorrection

In the event that your vision was over or undercorrected during your surgery, you may need to go back to glasses or contacts or even get an additional surgery to remedy the problem. Although it is rare, there is a possibility that your vision could worsen after getting PRK. Being aware of these possibilities and speaking to your doctor about them will make the process a lot smoother.

4. Risk of infection

Because PRK requires removing the outer layer of the cornea which serves as a natural protective barrier, your eyes are slightly more vulnerable to infection post-PRK. However, this risk can be minimized greatly if you are diligent about your post-operative dos and don’ts.

PRK dos and don’ts:

Do:

• Follow up with your doctor
• Use your eye drops as prescribed
• Wear sunglasses to avoid bright lights
• Consult your doctor before and after your procedure about medications to help with possible discomfort

Don’t:

• Rub or touch your eyes
• Participate in strenuous activities
• Drive until you are safe to do so
• Swim
• Put on makeup or any cream products near your eyes
• Smoke

For many, a life without contact and glasses sounds like a dream — but if you suffer from already dry eyes or a thin cornea, you may wonder whether there are good alternatives to LASIK. The good news? The road to better vision doesn’t stop at LASIK. There are several other options such as EVO Visian ICL or photorefractive keratectomy PRK surgery that can bring you the clear vision you’ve been hoping for.

At Eye Center of Texas, we offer a range of vision corrective surgery options including LASIK, EVO Visian ICL, and PRK. Depending on your unique vision and goals of the procedure, one of these procedures may be a great fit for you.

What can you do if you can’t get LASIK?

EVO Visian® ICL Lens

The EVO Visian ICL lens is an implantable Collamer lens that is an excellent alternative to LASIK for astigmatism as well as for patients who are not a good candidate for LASIK due to dry eyes, thin corneas, and high levels of nearsightedness.

When comparing the LASIK vs. ICL procedures, during EVO, a removable lens is placed behind the colored part of your eye (your iris) through a small hole rather than creating a flap and reshaping your cornea with a laser. Not only does this provide most patients with immediate vision improvements, but unlike LASIK which permanently changes the shape of your eye, it allows your eye surgeon to remove the lens at a later date if you require additional eye surgery. The entire procedure is very quick and virtually painless, taking only 20-30 minutes.

Other benefits of EVO Visian ICL include:

• Clear, sharp vision
• Short recovery time
• Offers UV protection
• Not visible once they are placed
• Can improve night vision
• Does not cause dry eyes

Photorefractive keratectomy (PRK)

Patients that are looking for a safe alternative to LASIK due to dry eyes or thin corneas may want to consider PRK vision corrective surgery. PRK is a refractive surgery that removes the outer layer of your cornea to allow access to the cornea without creating an incision. It then uses a laser to help correct vision loss due to nearsightedness, farsightedness, and astigmatism similar to LASIK.

Because the outer layer of your cornea is being removed entirely, the recovery time for PRK is a bit longer than it is for LASIK but it is still a great option for patients who want to break free of their contacts and glasses but aren’t a good candidate for LASIK.

If you’ve already tried LASIK and are curious about additional eye treatments to further improve your vision, you are able to get PRK after LASIK although it is rarely needed.

Refractive lens exchange (RLE)

RLE is a vision corrective surgery that replaces your entire natural lens with an artificial intraocular lens. This is a great alternative to LASIK for patients who struggle with age-related vision changes or presbyopia, a condition that gradually affects the eye’s ability to focus on objects that are close-up.

The RLE procedure is very similar to cataract surgery except in RLE, you’re removing a clear lens rather than a cloudy one. Most patients can resume normal activities after a week of resting but may not experience completely clear vision for a couple of weeks.

What is the safest corrective eye surgery?

Each of the above-mentioned eye surgeries has had high success rates and is considered a safe procedure. That said, the safest corrective eye surgery for you will depend on your vision impairments, individual goals, the thickness of your cornea, and any other existing symptoms.

For example, if you’re looking for LASIK alternatives for dry eyes, you may be a good candidate for either PRK or EVO Visian ICL. But because EVO Visian ICL is only used to treat nearsightedness or nearsightedness with astigmatism, if you have dry eyes and are farsighted, the best alternative for you may be PRK.

Need an alternative to LASIK? Eye Center of Texas can help you choose the right vision corrective surgery for you.

There are many factors to consider when it comes to choosing the right alternative to LASIK for you. You’ll want to take into consideration aspects such as your prescription, other symptoms, your lifestyle, and the types of benefits you are seeking. Fortunately, the best LASIK surgeon in Houston, TX at Eye Center of Texas will be able to tell you whether or not you’re a good candidate for LASIK and inform you of other options to help you achieve your goal of a life without dependence on glasses or contact lenses.

If you’re looking for an eye doctor to help explain your vision corrective surgery options and recommend a treatment plan tailored to your needs, look no farther than Eye Center of Texas.

Patients who are considering corrective laser surgery, particularly PRK surgery, should familiarize themselves with some do’s and don’ts after PRK surgery to encourage a speedy and painless recovery.

Photorefractive keratectomy (PRK) is an outpatient laser procedure that usually only takes about fifteen minutes and produces 20/40 vision in 95% of those who elect to get it. If you are thinking about taking the next step in making poor vision an ailment of the past, keep reading to get an idea of what to expect during and after PRK surgery.  

What to expect during PRK surgery

Is PRK eye surgery safe? The actual procedure is quite short, usually finishing up in just under 15 minutes. We understand that the experience can be nerve-wracking, so we offer an oral sedative for your comfort if you feel you could use it. 

Your ophthalmologist will administer numbing drops in your eyes to reduce discomfort and work on one eye at a time, gently removing the top layer of your cornea (epithelium) and reshaping its irregularities with ultraviolet light. This beam is only used on the surface of your cornea and does not interfere with the corneal flap in the same way that LASIK does, it does however make the healing process a bit longer because the epithelium needs to regrow instead of just being reattached. 

Continue reading: PRK vs LASIK recovery time

When the procedure is finished the surgeon will place a soft bandage contact lens on your eye, which both protects it and encourages healing of your cornea. You will be given eye drops (which you should use early and often over the following weeks) and consummate instructions before being driven home to rest.

The Don’ts: What can you not do after PRK surgery? 

What you can do is rarely as important as what you cannot do when recovering from surgery. You probably have some questions like “Can you go outside after PRK surgery?” or “How soon can I drive after PRK surgery?” Here is a list of a few don’ts that will complicate recovery:

• Do not under any circumstances rub or touch your eyes: It can displace the bandage contact lens and land you back in the office for a replacement.
• Do not exercise or physically exert yourself: Perspiration can irritate and dry your already irritated and dry eyes.
• Do not drive until your doctor tells you it is safe to do so.
• Do not swim. This means no pools, no hot tubs, and no steam rooms. You may shower starting the day after your procedure but keep those eyes shut to make sure soap and water get nowhere near your eyes.
• Avoid dust, dirt, and smoke.
• Avoid eye makeup and skin creams around the eyes for a week after surgery.
• Avoid bright lights.

The Dos: Recovery tips for PRK surgery

The best way to ensure a comfortable recovery is to lay the groundwork. Inform your boss that you might need a couple of days off of work to ensure you are fully recovered before returning. It can take a few days for your vision to begin to clear up but if you are patient with your eyes and communicative with your doctor, you will have nothing to worry about. Here is some more practical advice:

• Follow up with your doctor: You can expect vision changes in the positive and negative as your eyes heal. It is normal for your eyes to feel dry for a few weeks following the procedure.
• Use your eye drops!
• Wear eye shields at night following the procedure.
• You may return to work once the bandage contact lens has been removed. If the bandage contact comes out do not attempt to put it back in and call your doctor.
• You will experience increased sensitivity to bright lights. Wear sunglasses, even during the day and indoors, for the first few days following the procedure.
• Consult your doctor before and after your procedure about meds to help with possible discomfort.
• Be aware of the PRK side effects so that you know when (and more importantly) when not to be alarmed. Things like dry eyes and blurry vision should not worry you.

Considering PRK surgery? The experts at Eye Center of Texas are here to help.

Our team at Eye Center of Texas has been working to give patients the eyesight that they deserve for years. With the help of surgeons like cornea specialist  Dr. Yasir Ahmed, we are able to put the best minds and the most advanced techniques to work in service of your vision.

If you struggle with poor eyesight and are looking for ways to correct it without the use of contact lenses or glasses, you may find yourself wondering “what is PRK eye surgery?”

Photorefractive keratectomy (PRK) is an outpatient laser eye surgery that focuses on reshaping the cornea to treat astigmatism, nearsightedness, and farsightedness. The entire procedure takes up to 15 minutes and will likely have you back on your feet in just a couple of days.

You don’t have to live with poor eyesight. See how PRK eye surgery can permanently improve your vision and how it compares to LASIK.

What to expect during PRK laser eye surgery

PRK treats refractive errors in your eyes using a laser to reshape parts of your cornea. This process adjusts the way light is bounced into your retina, improving your eyesight.  

Before going into surgery

In your appointments leading up to your PRK surgery, you and your eye surgeon should review the risks, benefits, and costs. He or she will test and examine your vision to determine whether PRK eye surgery is right for you.

Immediately before the eye surgery, you will receive numbing drops in your eyes and an oral sedative if necessary.

During PRK surgery

The surgery itself won’t last longer than 10 to 15 minutes. During the procedure, your eye surgeon will gently remove the top layer of your cornea to expose the part of your eye that needs to be reshaped. This removed outer layer will grow back on its own while you are healing. The laser in PRK, which delivers a pulsing beam of ultraviolet light, is used on the surface of the cornea, not underneath the corneal flap like in LASIK.

Recovery after surgery

You won’t be able to drive for up to a week after the surgery so be sure you have a trusted ride home. There may be some pain or discomfort for the first 24 to 36 hours so you’ll need to ensure that you can get adequate rest, avoid physical activity, and avoid any products that could cause irritation or infection to your eye.

So, how long does it take to recover from PRK eye surgery? 

The initial recovery can take a couple of days and may require some pain medication for a day or two. Your doctor will place an eye bandage similar to a contact lens over your eyes while the top layer of your cornea regenerates. There may be some light sensitivity or blurred vision in those first couple of days but your vision should stabilize after the initial recovery.

Full recovery will take about a month but you’ll be back to normal once the eye bandage is removed a few days post-surgery.

PRK surgery side effects

There are a few expected PRK surgery side effects to keep in mind during the first couple days of the healing process including:

• Mild to moderate discomfort or itching
• Light sensitivity
• Seeing halos of light for the first few weeks
• Cloudy or hazy vision

If you notice any unusual symptoms or the above side effects persist, call your ophthalmologist immediately.

PRK vs. LASIK

Chances are if you’re wondering “what is PRK eye surgery?”, you are also curious about LASIK and the differences between the two.

Both laser eye surgeries utilize the same corrective portions when reshaping the cornea with slight variances in how the doctor accesses the cornea. As mentioned, with LASIK, the surgeon will access the surface of your cornea by creating a corneal flap. Whereas during a PRK procedure, the top layer of your cornea, or the epithelium, is removed to allow access to the irregularities needing to be corrected.

Another big difference between the two procedures is their recovery time. Since the hinged flap can simply be realigned after the procedure, your vision will likely be functional immediately after your LASIK procedure. 

Wondering why to choose PRK over LASIK? Your ophthalmologist might suggest PRK eye surgery over LASIK if you have certain structural variances, like a thin cornea or dry eyes, that make LASIK unsafe. Your doctor might also suggest you receive PRK after LASIK if you did not receive the desired outcomes.

FAQs

Is PRK worse than LASIK?

One eye surgery isn’t worse than the other. They are both fairly low-risk, dependable procedures with good outcomes. PRK does take a bit longer, has a slightly longer recovery time, and may cause some discomfort following the procedure. But there is less of a risk for dry eyes and/or your corneal thickness to be affected if you already have thin corneas.

Continue reading: Am I a good candidate for LASIK surgery?

Does PRK or LASIK last longer?

The PRK surgery takes a bit longer than LASIK due to the fact that it often requires two lasers — one to remove the epithelium and one to correct the cornea. The entire process is typically done in less than 15 minutes.

How long after PRK can you wear contacts?

Can you wear contacts after PRK? Yes, but you shouldn’t need to. PRK is a refractive surgery that helps correct vision loss. Should you need to wear contacts after the procedure, opt for soft contact lenses as rigid contact lenses may not fit correctly after surgery.

If you are interested in wearing soft lenses or decorative contacts, wait at least six months.

If you’ve been considering laser eye surgery, PRK might be on your radar, and may find yourself wondering, is PRK eye surgery safe?

Photorefractive keratectomy (PRK) is a type of laser eye surgery used to treat vision loss or astigmatism. What is the PRK success rate? According to the FDA, about 95% of PRK patients achieve 20/40 vision without the need for corrective lenses or glasses one year post-surgery. As with any medical procedure, there are risks, but PRK eye surgery is generally a very safe and predictable procedure with great outcomes.

With PRK, poor vision can be an ailment of the past. In this article, we’ll cover what you can expect during and after PRK eye surgery.

What happens during PRK eye surgery?

The PRK procedure itself is fairly short, lasting only around 15 minutes long. Your ophthalmologist will use numbing drops in your eyes before the procedure and offer an oral sedative if you feel you need it. 

Then they will gently remove the top layer of the cornea, or the epithelium, and reshape the irregularities with a pulsing beam of ultraviolet light. The outer layer that was removed will regenerate while you’re healing. To help it along, your doctor will place a protective bandage over your eye. This eye bandage will be removed a few days after your procedure.

Recovery: the do’s and don’ts after PRK surgery

Recovery for PRK is a little longer than LASIK due to the nature of the surgery. In LASIK, the corneal flap can simply be realigned after the procedure. But in PRK, the outer layer that was scraped away needs time to grow back.

You may experience some slight discomfort and pain immediately after the surgery and for the first 24 to 36 hours after. It’s best to take off work for the first couple of days and avoid driving yourself home from the surgery. 90% recovery can take up to a month but you’ll be back to your normal activities a few days post-surgery.

Here are some other tips for the week following your PRK procedure:

• Do not rub or touch your eyes
• Avoid wearing eye makeup
• Avoid swimming, hot tubs, and dry or dusty environments
• You may shower, but do your best to avoid getting water in your eyes
• Do not drive until you receive your doctor’s approval
• Use post-operative drops as often as needed
• Wear your eye shields at night
• Use sunglasses for at least the first three days

If you have any questions or concerns about the recovery process, please contact your doctor.

The side effects of PRK

Some typical PRK surgery side effects to keep an eye out for in the first week of recovery include:

• Mild to moderate discomfort or itching
• Light sensitivity
• Seeing bursts or halos of light for the first few weeks
• Cloudy or hazy vision (corneal haze)

If you notice any unusual symptoms such as pus, swelling, and/or fever, or the above side effects persist, call your ophthalmologist immediately.

What are the long-term effects of PRK?

Is PRK safe long term? Generally speaking, PRK is a safe laser eye surgery with high rates of success. That said, although they are rare, there is always a chance for long-term risks. The main long-term risks of PRK include the loss of vision that cannot be corrected, double vision, severe eye damage, and night vision issues like seeing glares or halos at night.

What’s the difference between PRK vs. LASIK?

The biggest difference between LASIK and PRK is the procedure process itself and the recovery time. The cornea is reached by removing the outer layer in PRK, but in LASIK the doctor reaches the cornea through a corneal flap. This difference in technique accounts for a longer healing time for PRK patients. Waiting a few extra days for your PRK recovery can lead to year after year of clear vision and a vastly improved quality of life.

You may be wondering, “which eye surgery is best for me?”
(more…)

At the Eye Center of Texas, we want to make sure our LASIK and PRK patients can see clearly and have the healthiest eyes possible. This means carefully screening our patients and doing whatever we can to prevent complications.
While wavefront LASIK allows excellent custom laser eye surgery results, there are some cases in which LASIK is a poor option for vision enhancement. With that in mind, let’s consider why corneal thickness is so important.
What Is LASIK Surgery?
LASIK is a refractive surgery procedure that involves the use of lasers to reshape the cornea, which is the topmost central transparent layer of the eye. By reshaping the cornea, the passage of light through the eye is improved. Light will focus on a single point on the retina, which is the light sensitive tissue located at the backs of the eye.
LASIK is ideal for treating the following refractive errors:

• Nearsightedness (myopia)
• Farsightedness (hyperopia)
• Astigmatism

How LASIK Is Performed?
During LASIK surgery, a flap is created in the topmost portion of the cornea, which is known as the epithelium. Once the epithelial flap is lifted, a laser can then reshape the rest of the cornea to improve vision quality. The flap is set down after the laser contouring is completed.
Why Corneal Thickness Matters:
Good candidates for LASIK have corneas that are of regular thickness. Corneal thickness matters since it’s important to have sufficient corneal tissue in place to be reshaped. Thin corneas can make it difficult to create an epithelial flap. A lack of corneal tissue can make the surgery risky. The laser will remove a minute amount of corneal tissue, but if there is not enough corneal tissue in place this can result in keratoconus (an outward bulging of the eye) as well as other serious complications.
Can People with Thin Corneas Undergo LASIK?
In general, LASIK is a bad idea for people who have thin corneas or corneas that are irregularly shaped. This is just a common sense approach to laser vision correction that helps prevent serious complications and other issues.
Alternatives to LASIK for People with Thin Corneas:
If you do have thin corneas, there are other laser vision correction options that work on similar principles. This includes PRK. Rather than create a corneal flap, these surgery will involve removal of the epithelium or the shifting of the epithelium to allow for corneal reshaping.
In terms of results, these LASIK alternatives can each enhance vision in a significant way, with results that are comparable to LASIK. Healing times and overall healing experience may be different from LASIK, but patients should noticed improved vision without the need for corrective prescription lenses.
Discussing Your Treatment Options
During the consultation process, we can assess the thickness of your corneas and determine the ideal treatment option for you and your needs. We will work closely with you each step of the way to ensure you undergo optimal treatment for your vision needs. This includes a full discussion of the risks and benefits of laser eye surgery and why one option may be better for you than another.

When patents come to us to find out if they are a good candidate for LASIK vision correction we conduct a very thorough eye examination – because not everyone is a good candidate .  For example, your cornea might be too thin, or the shape of your eye might not be appropriate for LASIK.  ECT also offers PRK, which is an excellent option to improve your vision.

What is LASIK?

LASIK is the most popular surgical procedure to correct vision problems. LASIK is a type of laser vision correction performed by a surgeon using a computer-controlled laser that emits precise pulses of energy to reshape the cornea. LASIK dramatically reduces the need for glasses or contact lenses by treating nearsightedness, farsightedness and astigmatism. After LASIK, nearly all patients see well enough that they don’t need glasses or contacts for most or all activities requiring distance vision.

What is PRK?

PRK, which stands for photo-refractive keratectomy, works in exactly the same general way as LASIK by reshaping the cornea. While both LASIK and PRK are two-step processes, in PRK the first step is different. Whereas LASIK involves providing the laser treatment under a flap, PRK is the application of the laser treatment on the corneal surface.

What is Clear Lens Exchange?

This procedure is much like cataract surgery, where the natural lens of the eye is exchanged for a custom lens implant. So, when LASIK or PRK is not the best option for you, we most likely have other procedures to improve your vision!
The only way to know what procedure is right for you is to schedule a no-obligation evaluation. We will do a comprehensive set of specialized tests and talk to you about what will work best for your eyes. Our friendly LASIK Counselors and Physicians look forward to seeing you to answer all your questions.
