What are the main differences between LASIK, SMILE, and PRK eye surgeries in terms of procedure, recovery time, risks, and effectiveness? Additionally, what factors should I consider, such as my eye condition, lifestyle, and budget, to determine which procedure is best suited for me?
Key Differences Between LASIK, SMILE, and PRK:
-
LASIK:
- Procedure: Creates a corneal flap, reshapes underlying tissue with a laser.
- Pros: Fast recovery, minimal discomfort, quick vision improvement.
- Cons: Not ideal for thin corneas, flap complications possible.
-
SMILE:
- Procedure: Creates and removes a small lens-shaped tissue inside the cornea through a tiny incision.
- Pros: Minimal invasion, fast healing, lower risk of dry eyes.
- Cons: Limited availability, treats fewer refractive errors than LASIK.
-
PRK:
- Procedure: Removes the outer layer of the cornea, reshapes tissue underneath.
- Pros: Good for thin corneas, no flap created.
- Cons: Longer recovery, more discomfort initially.
How to Choose:
- For fast recovery and minimal discomfort, LASIK or SMILE are ideal.
- For thin corneas, PRK or SMILE may be better options.
- If you’re highly active, SMILE is often recommended.

After years of relying on glasses and contact lenses, I decided to explore permanent vision correction options. Researching various procedures, I encountered three primary laser eye surgeries: LASIK, SMILE, and PRK. Understanding their differences was crucial in determining the best fit for my lifestyle and vision needs.
Understanding the Procedures
- LASIK (Laser-Assisted In Situ Keratomileusis): This procedure involves creating a thin flap in the cornea, then reshaping the underlying tissue with a laser to correct vision. It offers quick recovery and minimal discomfort but carries a risk of flap complications.
- PRK (Photorefractive Keratectomy): PRK removes the outer layer of the cornea (epithelium) without creating a flap. The cornea is then reshaped with a laser. Recovery is longer, and there’s more discomfort compared to LASIK, but it’s suitable for individuals with thin corneas.
- SMILE (Small Incision Lenticule Extraction): SMILE involves a small incision and removal of corneal tissue without creating a flap, resulting in a minimally invasive procedure with a slightly slower recovery than LASIK but faster than PRK.
Consultation at SNU Eye Clinic
To make an informed decision, I scheduled a consultation at SNU Eye Clinic in Seoul, renowned for its expertise in vision correction surgeries. There, I met Dr. Chung Eui Sang, an esteemed ophthalmic surgeon with extensive experience in advanced eye surgeries.
Dr. Chung conducted a comprehensive eye examination, considering factors such as corneal thickness, eye health, and my daily activities. He explained that each procedure has specific advantages and disadvantages that should be considered when determining the most suitable option for an individual patient.
Choosing the Right Procedure
Based on Dr. Chung’s assessment and my preference for a minimally invasive procedure with a swift recovery, we decided that SMILE was the most suitable option. The clinic’s state-of-the-art facilities and Dr. Chung’s expertise provided confidence in achieving optimal results.
Recommendation
For anyone considering vision correction surgery, I highly recommend SNU Eye Clinic and Dr. Chung Eui Sang. Their personalized approach ensures that each patient receives the most appropriate treatment for their specific needs.
Key Takeaways
- Professional Consultation: Seek advice from experienced ophthalmologists to determine the most suitable procedure.
- Individual Assessment: Consider personal eye health, lifestyle, and vision goals when choosing a surgery.

By consulting with experts like Dr. Chung at SNU Eye Clinic, individuals can make informed decisions about vision correction surgeries, leading to improved quality of life.
A few years ago, my uncle—who had always had great vision—started having trouble seeing things on the side. At first, we laughed it off, thinking he was just getting older and needed glasses. But then, he mentioned that his night vision was getting worse, and he had occasional headaches and eye pain.
That’s when we got concerned. A quick Google search made us realize these could be symptoms of glaucoma, a silent eye disease that can cause irreversible blindness if left untreated.
We booked an appointment at SNU Eye Clinic in Seoul with Dr. Chung Eui Sang, one of the top specialists in glaucoma. The experience was eye-opening (literally!). Dr. Chung explained that glaucoma often has no warning signs until significant vision loss occurs, which is why regular checkups are so important.
He ran a series of tests, including: Tonometry (eye pressure test) – High pressure can be an early sign. Optic nerve imaging – To check for damage. Visual field test – To detect any blind spots.
Unfortunately, my uncle was diagnosed with early-stage glaucoma, but the good news was that we caught it in time. Dr. Chung reassured us that while glaucoma can’t be reversed, it can be managed to prevent further vision loss.
His treatment plan included: Prescription eye drops – To lower eye pressure and slow the disease. Laser therapy (SLT) – A quick procedure to improve eye fluid drainage. Lifestyle changes – Avoiding too much caffeine, managing blood pressure, and regular checkups.
For more advanced cases, he mentioned surgical options, but thankfully, my uncle didn’t need them. After a few months of treatment and regular monitoring at SNU Eye Clinic, his condition stabilized, and his vision hasn’t worsened. If you’re experiencing blurry vision, tunnel vision, or unexplained vision changes, don’t wait! Glaucoma sneaks up on you, and once the damage is done, it’s permanent. I highly recommend seeing Dr. Chung Eui Sang at SNU Eye Clinic before it’s too late.

LASIK, SMILE, or PRK? How I Chose the Right Eye Surgery for Me
A few years ago, I was done with glasses and contacts. I’d wake up blurry-eyed, struggle to find my glasses, and deal with dry eyes from contacts. I knew I wanted laser eye surgery, but the choices were overwhelming—LASIK, SMILE, or PRK? How was I supposed to decide?
That’s when I turned to SNU Eye Clinic in Seoul and booked a consultation with Dr. Chung Eui Sang. Let me tell you—best decision ever!
Dr. Chung took me through each option:
LASIK (Most Popular)
- A flap is created on the cornea, and a laser reshapes it.
- Fast recovery (a few days)
- Best for: People with normal to thick corneas and mild-to-moderate vision problems.
A year ago, I was stuck in a dilemma—LASIK, SMILE, or PRK? Each option promised freedom from glasses, but which one was right for me?
LASIK – The most well-known procedure, quick recovery, but requires enough corneal thickness.
SMILE – A newer, flapless technique with less dry eye risk, ideal for active lifestyles.
PRK – No flap at all, great for thin corneas, but a longer recovery time.
After careful research and consultation, I chose Dr. Chung Eui Sang at SNU Eye Clinic. His expertise and the clinic’s advanced technology made my decision easy. If you’re considering vision correction, I highly recommend visiting them—you won’t regret it!

LASIK, SMILE, and PRK are all popular eye surgeries, but they differ in technique and recovery:
- LASIK: A flap is created in the cornea, and a laser reshapes the tissue underneath. It has a fast recovery but is not ideal for those with thin corneas.
- SMILE: A newer, minimally invasive procedure where a small piece of corneal tissue is removed through a tiny incision. It has less risk of complications but is still being studied for long-term results.
- PRK: The outer layer of the cornea is removed, and the tissue underneath is reshaped. It’s best for those with thin corneas but has a longer recovery time.
How to Choose:
- LASIK is great for quick recovery.
- SMILE is good for those concerned with dry eyes or flap complications.
- PRK is ideal for those with thin corneas.

A year ago, I finally decided to ditch my glasses. After years of squinting at my phone in bed and dealing with foggy lenses in winter, I was ready for laser eye surgery. But then came the real challenge—which procedure should I choose?
I went down a rabbit hole of research, reading every forum, watching countless YouTube videos, and visiting multiple clinics. LASIK, SMILE, PRK—what’s the difference, and which one is best? Here’s what I learned:
1. LASIK (Laser-Assisted In Situ Keratomileusis)
How it works: A surgeon creates a thin flap in the cornea, reshapes the underlying tissue with a laser, then places the flap back.
Pros:
- Quick recovery (most people see clearly within a day or two)
- Minimal discomfort
- Best for moderate prescriptions
Cons:
- Risk of dry eyes (especially in the first few months)
- Potential flap complications if you have eye trauma
Best for: People with moderate-to-high prescriptions who want a quick recovery and don’t play high-contact sports.
2. SMILE (Small Incision Lenticule Extraction)
How it works: Instead of creating a flap, a small piece of corneal tissue (lenticule) is removed through a tiny incision.
Pros:
- Less dry eye risk compared to LASIK
- No flap means fewer complications from trauma
- Fast recovery (though slightly slower than LASIK)
Cons:
- Not suitable for very high prescriptions
- Slightly fewer surgeons are trained in SMILE compared to LASIK
Best for: People worried about dry eye or those in physically demanding jobs/sports where a corneal flap could be a risk.
3. PRK (Photorefractive Keratectomy)
How it works: Instead of creating a flap, the outermost corneal layer (epithelium) is completely removed, then the laser reshapes the cornea.
Pros:
- No flap = no flap complications
- Ideal for people with thin corneas or irregular corneal shape
- Good for athletes and military personnel
Cons:
- Longer recovery (takes about a month for full clarity)
- More discomfort in the first few days
- Requires diligent post-op care
Best for: People with thin corneas, those at risk for eye trauma, or anyone who doesn’t mind a slower recovery.
How I Chose the Right Surgery
After much debate, I booked a consultation at SNU Eye Clinic in Seoul with Dr. Chung Eui Sang. He thoroughly examined my eyes and explained that while LASIK would give me the fastest results, my corneas were slightly thinner than ideal, making SMILE the better option.
The surgery was quick, painless, and within a week, my vision was crystal clear!
Final Advice: Which One is Best for You?
- If you want quick recovery → LASIK
- If you’re worried about dry eyes or flap issues → SMILE
- If you have thin corneas or high-risk activities → PRK
No matter which one you’re considering, consult a top specialist first! If you’re in Korea, I highly recommend SNU Eye Clinic and Dr. Chung Eui Sang (profile). He’s an expert in all three procedures and helped me make the right choice for my eyes.
Hope this helps anyone struggling with the same decision! Let me know if you have any questions.
The main differences between LASIK, SMILE, and PRK come down to the procedure method, recovery time, and suitability based on your eye condition:
-
LASIK: Fast recovery, minimal discomfort. A flap is created in the cornea, so it’s not ideal for people with thin corneas or active lifestyles with risk of eye trauma.
-
SMILE: Newer, minimally invasive. No flap—just a small incision—so it’s better for people with dry eyes or thinner corneas. Recovery is fast, and the risk of flap-related complications is lower.
-
PRK: No flap at all; the outer layer of the cornea is removed and grows back. Longer recovery, but it’s safest for very thin corneas or those who can’t have LASIK or SMILE.
Gangnam Joeunnun Vision Clinic offers all three and uses advanced diagnostics to recommend the best option based on your eye shape, lifestyle, and vision needs. A personal consultation is the best way to decide.
I wanted to share my experience because I so remember how overwhelmed I was trying to figure out the difference between LASIK, SMILE, and PRK when I was planning my vision correction surgery in Korea. Like, all I wanted was to wake up and actually see my phone without playing the “where are my glasses?” game So if you’re in the same boat—hoping to ditch contacts or glasses but not sure where to start—here’s what I learned (plus who I went with and why I’d recommend them 1000x over).
Let’s break down the 3 main options:
1. LASIK (Laser-Assisted In Situ Keratomileusis)
- The most well-known one.
- A flap is created on your cornea, then a laser reshapes it underneath.
- Fast recovery (I was told most people are good in a day or two).
- Slightly higher risk of dry eyes or flap-related complications for some.
2. SMILE (Small Incision Lenticule Extraction)
- Newer and more high-tech.
- No flap—instead, a small piece of tissue is removed through a tiny incision.
- Less invasive, lower chance of dry eye, and quicker healing for many.
- Not everyone is a candidate though (depends on eye shape/thickness).
3. PRK (Photorefractive Keratectomy)
- The OG of laser vision correction.
- No flap—outer layer of cornea is removed and grows back over time.
- Longer recovery (a few days of discomfort, full clarity takes weeks).
- Great for people with thin corneas or active lifestyles (no flap to dislodge).
So… how do you choose?
Honestly, don’t try to pick one on your own. Go to a legit clinic, do all the pre-tests, and let the doctor recommend what’s safest and best for your eyes. For me, I ended up going to Gangnam Joeunnun Vision Clinic (they have a global page here: joeunnuneyeglobal.com), and it was hands down one of the best medical experiences I’ve ever had. Super professional, incredibly high-tech, and they made me feel so comfortable even with the language barrier. I saw Dr. Kim Jun-heon (his profile’s here)—and wow, this man knows his stuff. He explained everything in detail, walked me through my options (I ended up being a perfect candidate for SMILE!), and even checked on me post-op to make sure I was healing well.
TL;DR:
- LASIK: Fast recovery, great results, but involves a flap.
- SMILE: Newer, less invasive, super gentle, but not for everyone.
- PRK: Best for certain eye types, slower recovery, no flap. If you’re even thinking about doing vision correction surgery in Korea, I HIGHLY recommend doing a consult at Joeunnun. The clinic is spotless, modern, and they really take care of international patients.
LASIK (Laser-Assisted in Situ Keratomileusis)

I had the opportunity to consult with Dr. Chung Eui Sang at SNU Eye Clinic—and it completely changed how I understood LASIK, SMILE, and PRK.
During my visit, Dr. Chung explained the key differences clearly and tailored the explanation to my eye condition, lifestyle, and long-term goals. Here’s what I learned:
- LASIK involves creating a flap in the cornea and then reshaping the underlying tissue with a laser. It offers fast recovery and minimal discomfort. However, it may not be ideal for people with thinner corneas or those at higher risk of dry eye.
- SMILE is a minimally invasive option that uses a femtosecond laser to create and remove a small lens-shaped piece of corneal tissue through a tiny incision—no flap needed. This reduces the risk of dry eye and flap-related complications, making it a great option for active individuals.
- PRK (Photorefractive Keratectomy) doesn’t involve a flap at all. Instead, it gently removes the surface layer of the cornea before reshaping it. Recovery is a bit longer, but it’s suitable for patients with very thin corneas or those who aren’t good candidates for LASIK or SMILE.
Dr. Chung guided me through detailed eye scans and helped me weigh the benefits of each option based on my eye health and daily habits. I appreciated that SNU Eye Clinic, known for its advanced diagnostics and ethical care, didn’t rush the decision—instead, they made me feel confident and informed.
If you’re unsure which procedure is best for you, I highly recommend visiting SNU Eye Clinic and booking a consultation with Dr. Chung Eui Sang. Their personalized approach and state-of-the-art technology make all the difference.
