LASIK and PRK eye surgeries help patients achieve clear vision without glasses or contact lenses. About 90% of patients who undergo either procedure attain 20/20 vision or better. Both surgeries effectively correct common vision problems like nearsightedness, farsightedness, and astigmatism, though they use different approaches.
Your choice between LASIK and PRK depends largely on your specific eye characteristics and lifestyle needs. LASIK offers quicker healing – most patients return to normal activities within 24 hours. PRK patients need more recovery time, typically about a month for complete healing. The cost difference also matters in decision-making. LASIK costs around $2,200 per eye, while PRK usually costs several hundred dollars less.
Talk with your eye doctor about which procedure better suits your vision needs. This guide explains the key differences between LASIK and PRK to help you understand your options. We’ll examine how each surgery works, compare recovery times, and discuss factors that determine which procedure might work best for you.
Understanding PRK and LASIK Basics
Our natural lens is like a camera lens – crystal clear in most of us. Both PRK and LASIK reshape this lens (the cornea) to correct vision problems, though they use different surgical approaches. Let’s explore how each procedure works to help you understand which might better suit your eyes.
What is PRK surgery?
PRK (Photorefractive keratectomy), developed in 1983, was the first laser vision correction surgery. During PRK, your eye doctor removes the cornea’s outer protective layer (epithelium). An excimer laser then reshapes the underlying corneal tissue to correct your vision.
The procedure takes just 1-2 minutes per eye. Your doctor first applies numbing drops to ensure your comfort. Then, using either a blade, laser, brush, or alcohol solution, they gently remove the epithelium. After reshaping the exposed corneal tissue with the laser, a protective contact lens bandage covers your eye until the outer layer naturally grows back.
PRK can effectively treat:
- Myopia up to -12 diopters
- Astigmatism up to 6 diopters
- Hyperopia up to 5 diopters
How LASIK works
LASIK takes a different approach to corneal reshaping. Instead of removing the outer corneal layer completely, your surgeon creates a thin, hinged flap. They make this flap using either a bladeless laser or a precise surgical tool called a microkeratome.
After numbing your eye, the doctor places a small device to keep your eyelids open. They create and lift the corneal flap, much like opening a tiny door. The excimer laser then reshapes the cornea underneath according to your specific vision needs. Finally, the flap returns to its natural position, where it heals on its own without stitches.
Key differences in approach
The main difference between these procedures lies in how they access your cornea. Here are other important distinctions:
- Corneal Treatment: PRK completely removes the outer corneal layer, letting it grow back naturally. LASIK preserves this layer by creating a hinged flap.
- Surgical Time: PRK takes about 1-2 minutes per eye, while LASIK needs 5-9 minutes per eye.
- Corneal Thickness: If you have thin corneas, PRK might work better since it doesn’t require creating a flap. Athletes and people in high-impact activities often choose PRK to avoid risks of flap complications.
- Procedure Complexity: Many eye doctors find PRK less complex than LASIK. PRK also helps enhance results after other eye surgeries like corneal transplants, LASIK, and cataract procedures.
- Long-term Results: Research shows both procedures work equally well for mild to moderate nearsightedness. Both achieve similar success rates in vision correction over time.
Modern technology has made both procedures highly precise. Today’s equipment creates detailed maps of your cornea, ensuring exact laser placement during surgery.
The Surgery Process Compared
The way smudgy lenses cause blurring of vision, changes to our cornea affect how clearly we see. Though PRK and LASIK both reshape the cornea, they use different surgical approaches. Let’s examine how each procedure works.
PRK procedure steps
PRK surgery begins with eye drops to numb your eye and ensure your comfort. Your doctor places a small device to keep your eye open during the procedure. The entire process takes about 15 minutes for both eyes.
Here’s what happens during PRK:
- Removing the Outer Layer: Your eye doctor removes the cornea’s protective outer layer (epithelium) using one of these methods:
- A gentle brush
- Laser technique
- An alcohol solution
- Special surgical instruments
- Reshaping Your Cornea: After removing the outer layer, the excimer laser precisely reshapes the corneal tissue underneath. This step takes just 30-60 seconds per eye. The laser removes tiny amounts of tissue without creating heat.
- Protecting Your Eye: Finally, your doctor places a special contact lens bandage over your eye. This protective lens stays in place for 5-7 days while the outer layer naturally grows back.
LASIK procedure steps
LASIK surgery typically takes less than 30 minutes for both eyes. The procedure follows several careful steps to ensure the best results.
Here’s how LASIK works:
- Getting Ready:
- Your eye receives numbing drops
- A gentle suction ring holds your eye steady
- A small device keeps your eye open
- Creating the Flap: Unlike PRK, LASIK involves making a thin, hinged flap in your cornea:
- The doctor uses either a precise laser or surgical tool
- They carefully lift the flap, like opening a tiny door
- One side stays attached
- Reshaping the Cornea: The laser reshaping varies based on your vision needs:
- For nearsightedness: Flattening the center
- For farsightedness: Removing tissue around the edges
- For astigmatism: Creating an even curve
- Closing the Flap: Your doctor gently puts the flap back in place, where it heals naturally without stitches.
During both procedures, you’ll focus on a target light while advanced tracking systems watch your eye movements. If your eye moves too much, the laser automatically stops, ensuring precise treatment. Some patients notice an unusual smell during the laser process, similar to burning hair.
After surgery, PRK patients wear a protective contact lens until the outer layer heals. LASIK patients might need a protective shield to prevent accidentally touching their eyes.
Your eye characteristics and lifestyle help determine which surgery suits you best. For example, if you have thin corneas or play contact sports, PRK might work better since it avoids risks associated with a LASIK flap. However, if you need to return to work quickly, LASIK’s faster recovery might be more suitable.
Recovery Timeline Differences
After laser eye surgery, your healing journey differs significantly between PRK and LASIK. Let’s explore what you can expect during recovery to help you prepare for the process.
First 24 hours after surgery
Concerned about pain during recovery? LASIK patients see vision improvements right away, though things look a bit foggy at first – like looking underwater. About 30 minutes after surgery, as the numbing medicine wears off, you might feel some burning and mild itching.
For the first day, your doctor will ask you to:
- Rest your eyes for 2-4 hours after returning home
- Avoid any heavy activity
- Wear sunglasses when outdoors
- Use your eye drops as prescribed
- Keep your hands away from your eyes
PRK patients need more careful attention initially. Your doctor places a special bandage contact lens over your eye right after surgery to protect the healing surface. Though you can see, your vision stays blurry during this time, and your eyes might feel sensitive to light with mild irritation.
Week 1 recovery experience
LASIK healing moves quickly in the first week. Most patients get back to their normal routine within 24 hours. You might notice some temporary effects:
- Dry eyes
- Sensitivity to light
- Slight redness
- Seeing halos around lights at night
- Some tearing
PRK takes more time to heal. The protective lens stays on your eye for 5-7 days while the surface grows back. During this period, you’ll likely experience:
- Blurry or unclear vision
- More sensitivity to light
- Eye discomfort
- Different levels of irritation
Your doctor will give you pain medicine and special drops to help with these symptoms. Keep your eyes away from dust and water during this early healing time.
Long-term healing process
The biggest difference between LASIK and PRK shows up in long-term recovery. With LASIK, your vision usually stabilizes within days, though complete healing takes several months. Most people return to work within 48 hours, but should wait at least four weeks before playing contact sports.
PRK healing follows this timeline:
- Surface layer healing: 3-5 days
- Less light sensitivity: 7-10 days
- Usable vision: 2-4 weeks
- Full stability: 3-6 months
Though PRK takes longer to heal, it offers some unique benefits. Research shows both procedures stay equally safe and effective over many years. Studies following patients for over 10 years find very few complications with either surgery.
The way vision improves differs between procedures. LASIK patients often see dramatic improvements within 24 hours. PRK vision gets better gradually, day by day. Your doctor will check your healing at follow-up visits, with best vision typically coming around three months for LASIK and up to six months for PRK.
For both procedures, following your doctor’s instructions carefully helps ensure the best results. Remember to use your eye drops, protect your eyes from sun damage, and keep all your follow-up appointments. These steps help your eyes heal properly and achieve the clear vision you’re hoping for.
Choosing Between PRK and LASIK
Talk with your eye doctor about whether PRK and LASIK might work for you. While both procedures effectively correct vision problems, your eye characteristics and lifestyle help determine which surgery fits best.
Cornea thickness considerations
We measure corneal thickness carefully before recommending either procedure. Most people have corneas about 555 microns thick. For LASIK surgery:
- Your cornea needs to be at least 500 microns thick
- The surgical flap takes up 90-160 microns, usually around 110 microns
- Your cornea must maintain 250-300 microns after surgery for eye health
If you have thinner corneas, PRK might work better for your eyes. PRK especially helps patients whose corneas measure less than 480 microns. Since PRK doesn’t create a flap, it preserves more of your corneal tissue.
Interestingly, if you have a stronger prescription (-8.00 or -9.00), you might see better results with PRK. This happens because LASIK needs enough remaining corneal tissue after reshaping, which becomes harder with stronger prescriptions.
Lifestyle factors
How do your daily activities affect your choice between these procedures? Consider these important factors:
Athletic Activities and Sports
- Do you play contact sports? PRK might work better for you
- PRK avoids risks of flap problems during physical activities
- Many athletes choose PRK because it heals more durably
Recovery Time Flexibility
- LASIK lets you return to work within 24 hours
- PRK needs about a week for initial recovery
- Can you take enough time off work for PRK recovery?
Medical Conditions
- If you have dry eye syndrome, PRK might feel more comfortable since LASIK can temporarily affect tear production
- Autoimmune conditions need special evaluation before either surgery
- Uncontrolled diabetes might affect how well your eyes heal
Age and Vision Stability
- You must be at least 18 years old
- Your vision prescription should stay stable for one year
- If you wear contacts, switch to glasses several weeks before surgery
Professional Requirements
- Some jobs make one procedure safer than the other
- If your work risks eye injury, consider PRK
- Need to return to work quickly? LASIK might suit you better
Post-operative Care Commitment
- PRK requires wearing a protective lens for about a week
- With LASIK, avoid touching your eyes during early healing
- Both surgeries need careful following of medication schedules and check-ups
Remember, choosing between PRK and LASIK isn’t one-size-fits-all. Your eye doctor will help evaluate your unique situation, considering your corneal health, lifestyle needs, and personal preferences. Both procedures have helped many patients achieve clear vision when chosen carefully for the right candidates.
Cost and Insurance Factors
The way smudgy lenses causes blurring of vision, unclear financial information can cloud your decision-making. Let’s examine the costs, insurance coverage, and payment options for both procedures.

Success Rates and Outcomes
Talk with your eye doctor about whether surgery is right for you. Both LASIK and PRK have shown remarkable success in helping patients achieve clear vision. Let’s examine how well these procedures work and what patients say about their results.
Vision improvement statistics
About 90% of patients achieve 20/20 vision or better with either procedure. This high success rate shows how effective modern laser eye surgery has become.
LASIK results show:
- Nearly 96% of patients see 20/25 or better two years after surgery
- About 98% achieve excellent corrected vision (CDVA)
PRK also delivers strong outcomes:
- Around 80% of patients reach 20/25 or better vision without correction two years later
- About 94% achieve excellent corrected vision
When comparing both procedures:
- LASIK shows slightly better effectiveness (1.00) than PRK (0.82)
- LASIK more predictably achieves the desired correction – 92% versus 65% for PRK
Like any procedure in body, results can vary based on your eye health, prescription strength, and corneal thickness. Long-term studies following patients for over 10 years show very few complications with either surgery.
Concerned about astigmatism correction? Here’s what research shows:
- After two years, about 59% of PRK patients had remaining astigmatism over 0.5 diopters, compared to 40% with LASIK
- For higher astigmatism levels over 1.0 diopter, numbers dropped to 20% for PRK and 6% for LASIK
Patient satisfaction levels
