Are you considering laser eye surgery to correct your vision? Photorefractive keratectomy (PRK) might be a viable option, especially if you don’t qualify for LASIK.
In this article, we’ll discuss the PRK procedure, recovery process, factors influencing recovery time, and costs. We’ll also go over how it compares to LASIK.
Let’s explore whether PRK could be your key to a clearer vision.
What is PRK, and What’s the Procedure Like?
Photorefractive keratectomy (PRK) is a type of laser eye surgery. It can be used as an alternative for people who don’t meet the criteria for LASIK.
Similar to LASIK, it reshapes the cornea to fix refractive errors. However, unlike LASIK, it removes the top layer of the cornea (the epithelium) to expose the underlying surface.
After the cornea is exposed, an excimer laser is used to reshape the cornea. The procedure typically takes about 30 to 60 seconds per eye. They’ll also give you a bandage contact lens to protect your eyes and help them heal.
PRK Aftercare and Recovery
After surgery, you’ll need some time to heal. Take some time to rest and follow your doctor’s instructions for aftercare.
They may prescribe medication, antibiotic eye drops, lubricating eye drops, and steroid drops to manage discomfort and prevent infection.
Here are our other recommendations for aftercare:
- Wear protective sunglasses to avoid excessive sun exposure.
- Taking medications as prescribed.
- Taking a few days off work to rest.
- Avoiding physical activities for up to a week.
- Avoiding contact sports until your doctor says otherwise.
- Avoid rubbing your eyes.
- Avoid contact with dirty water.
- Attending follow-up appointments to monitor the healing process.
What is PRK Surgery’s Outcome?
For the first few days, you can expect blurry vision and light sensitivity due to the surface layer of your cornea growing back. You can also expect some pain and discomfort during this time.
However, after the first few weeks, you’ll start to notice significant improvements in your vision, but this may fluctuate from time to time. Most people’s vision stabilizes after 3 to 6 months.
Although rare, some people may need to undergo a small enhancement procedure if their vision isn’t fully corrected. It’s also important to understand that everyone heals differently, and your experience may vary.
Factors That Affect Recovery Time
While the initial recovery for PRK is longer than LASIK, the duration can be affected by different factors, including:
- Degree of correction. Higher prescriptions often take a bit longer to stabilize.
- Individual healing. Some people just heal faster than others.
- Follow-up care. Attending your appointments and following post-op instructions matters. It lets your doctor catch potential issues early.
How Much is PRK Surgery?
The average cost of PRK ranges from $2,000 to $4,000 for both eyes. However, the cost may vary depending on your location, available facilities, and the surgeon’s experience.
Because PRK is considered an elective surgery, most insurance won’t cover the cost. Fortunately, you can talk to your surgeon about different financing options to cover some of the cost. Your health savings account (HSA) or flexible spending account (FSA) may also cover some costs.
What’s the Difference Between LASIK and PRK?
The main difference between PRK and LASIK is how your cornea heals. Because the epithelium is removed in PRK, it takes a few days for a new layer to grow.
Meanwhile, for LASIK, a flap is created and then put back in place. The flap is a natural bandage, so your vision will recover faster.
Which Procedure is Better For You?
Talk to your doctor or surgeon to determine which procedure is better for you. They’ll consider your eye health, prescription, lifestyle, and visual needs.
Here are some factors you and your doctor may consider when deciding between the two surgeries:
| LASIK | PRK | |
| Procedure | Involves creating a thin flap to reach the cornea. | Involves removing the epithelium to reach the cornea. |
| Vision Correction | Significant vision improvement within a day or two. | Vision improvement occurs within 5 days to a week |
| Recovery Time | Full recovery typically occurs within a few months. | Full recovery can take up to a month or longer. |
| Suitability | Better for people with thick corneas, moderate to high refractive errors, and participate in low-risk activities. | Better for people with thin corneas, dry eye tendencies, higher prescriptions, and participate in high-risk activities like contact sports. |
Choosing between LASIK and PRK is a personal decision best made in consultation with your eye doctor. By understanding the nuances of each procedure, you can make an informed decision that aligns with your vision goals.
