Whether you’re considering LASIK, PRK, SMILE, or ICL surgery, this guide will help you make an informed decision about the best option for your eyes.
Understanding Refractive Errors and Vision Problems
Before diving into the details of refractive surgery, it's important to understand the common vision problems these procedures aim to correct.
What Are Refractive Errors?
Refractive errors occur when the eye's shape prevents light from focusing directly on the retina, leading to blurred vision. The most common types include:
Myopia (Nearsightedness): Distant objects appear blurry while close objects remain clear.
Hyperopia (Farsightedness): Near objects appear blurry, while distant vision may be clearer.
Astigmatism: Vision is distorted due to an irregularly shaped cornea.
Presbyopia: Age-related difficulty focusing on close objects, usually occurring after age 40.
How Do Refractive Surgeries Help?
Vision correction surgeries reshape the cornea or implant corrective lenses to improve how light is focused on the retina, effectively reducing or eliminating the need for glasses or contact lenses. Modern advancements in laser technology have made these procedures safer and more effective than ever.

Overview of Vision Correction Surgeries Available in Korea
South Korea is at the forefront of ophthalmic surgery, offering the latest advancements in laser and lens-based procedures. The most popular options include:
LASIK (Laser-Assisted In Situ Keratomileusis)
Most widely performed refractive surgery.
Uses a laser to create a thin corneal flap, then reshapes the underlying cornea to correct vision.
Fast recovery—most patients experience clear vision within 24 hours.
PRK (Photorefractive Keratectomy)
Similar to LASIK but without creating a corneal flap.
Ideal for patients with thin corneas or active lifestyles (e.g., athletes, military personnel).
Longer recovery time than LASIK but with comparable visual outcomes.
SMILE (Small Incision Lenticule Extraction)
Newest laser eye surgery technique with minimally invasive technology.
Removes a small piece of corneal tissue (lenticule) through a tiny incision.
Less impact on the corneal structure, making it a better option for dry eyes.
EVO ICL (Implantable Collamer Lens)
A non-laser, reversible procedure that involves implanting a biocompatible lens inside the eye.
Best for high myopia or patients with thin corneas who are not LASIK candidates.
Provides high-definition vision with UV protection.
Each of these procedures has its own advantages and suitability criteria. The choice depends on factors like eye health, corneal thickness, prescription level, and lifestyle.
LASIK Surgery: The Most Popular Procedure
What Is LASIK Surgery?
LASIK (Laser-Assisted In Situ Keratomileusis) is the most well-known and widely performed laser vision correction procedure. It is popular because of its quick procedure time, minimal discomfort, and fast recovery. Most patients achieve 20/20 vision or better within a day or two.
How LASIK Works
The LASIK procedure is performed in a few simple steps:
Numbing eye drops are applied to ensure a painless experience.
A femtosecond laser creates a thin flap on the cornea.
A second laser (excimer laser) reshapes the underlying corneal tissue to correct vision.
The flap is repositioned, acting as a natural bandage.
The patient is sent home with post-op care instructions.
Who Is a Good Candidate for LASIK?
Individuals with stable vision prescription for at least 12 months.
Patients with healthy corneas (adequate thickness is required).
Those with mild to moderate myopia, hyperopia, or astigmatism.
Patients with no severe dry eye syndrome or corneal diseases.
Recovery and Results
Most patients experience dramatic improvement in vision within 24 hours. Some mild side effects, such as dry eyes or light sensitivity, may last for a few weeks but usually resolve on their own. Full stabilization of vision typically occurs within one to three months.
Common Side Effects of LASIK
Temporary dry eyes (managed with lubricating drops).
Glare and halos around lights at night (improves over time).
Mild discomfort or itching in the first few days.
Very rare complications (infection or undercorrection).
PRK Surgery: A Strong Alternative to LASIK
What Is PRK Surgery?
PRK (Photorefractive Keratectomy) was the first type of laser eye surgery and remains a widely used alternative to LASIK. While LASIK requires creating a corneal flap, PRK removes the outer layer of the cornea (epithelium), allowing the excimer laser to reshape the underlying tissue.
How PRK Works
The PRK procedure follows these steps:
Numbing eye drops are applied to minimize discomfort.
The epithelium (outer corneal layer) is removed using an alcohol solution or laser.
A laser reshapes the cornea to correct refractive errors.
A bandage contact lens is placed over the eye to aid healing.
Who Is a Good Candidate for PRK?
Individuals with thin corneas who are not suitable for LASIK.
Those at risk of corneal flap complications (e.g., athletes, military personnel).
Patients with mild to moderate myopia, hyperopia, or astigmatism.
PRK Recovery and Results
Unlike LASIK, PRK has a longer recovery period since the epithelium must regenerate. Key points:
Initial healing takes 5-7 days, during which vision may be blurry.
Full visual clarity takes about 1-3 months.
Final vision results are as good as LASIK but require more patience.
Why Some Patients Choose PRK Over LASIK
No risk of flap complications since no flap is created.
Better for individuals with thin corneas.
Ideal for people in contact sports where eye injuries are more likely.
Despite the longer recovery, PRK remains a preferred choice for many patients due to its safety and effectiveness.
SMILE Eye Surgery: The Latest Laser Vision Technology
What Is SMILE Eye Surgery?
SMILE (Small Incision Lenticule Extraction) is a relatively new minimally invasive laser eye surgery. Unlike LASIK and PRK, SMILE does not require a corneal flap or the removal of the epithelium. Instead, the surgeon creates a small disc (lenticule) inside the cornea, which is then removed through a tiny incision.
How SMILE Works
A femtosecond laser creates a lenticule (thin disc) inside the cornea.
A small 2-4mm incision is made to remove the lenticule.
By removing the lenticule, the corneal shape is altered, correcting vision.
Who Is a Good Candidate for SMILE?
Patients with moderate to high myopia (but not hyperopia).
Individuals prone to dry eye syndrome, since SMILE preserves more corneal nerves.
Those looking for a flapless, minimally invasive procedure.
SMILE Recovery and Results
Faster healing compared to PRK but slightly longer than LASIK.
Less dry eye risk compared to LASIK.
Excellent long-term results for myopia correction.
Why Some Patients Choose SMILE Over LASIK
Minimally invasive (no flap creation).
Better for patients with dry eyes.
Smaller incision means quicker healing and fewer complications.
Although SMILE is gaining popularity in Korea, it is not yet suitable for hyperopia correction like LASIK and PRK.
EVO ICL: A Non-Laser Alternative for High Myopia
What Is EVO ICL Surgery?
EVO ICL (Implantable Collamer Lens) is a non-laser, reversible vision correction surgery where a biocompatible lens is implanted inside the eye, in front of the natural lens. This procedure is ideal for patients who are not suitable for LASIK or SMILE due to high myopia or thin corneas.
How EVO ICL Works
A small incision is made in the cornea.
A collamer lens is inserted behind the iris, in front of the natural lens.
The lens stays permanently in place, correcting vision without removing corneal tissue.
Who Is a Good Candidate for EVO ICL?
Patients with moderate to severe myopia (up to -20.00D).
Those with thin corneas who are not eligible for LASIK or PRK.
Individuals looking for a reversible procedure.
EVO ICL Recovery and Results
Quick recovery—most patients see clearly within 1-2 days.
Does not cause dry eyes, making it suitable for sensitive patients.
Reversible—the lens can be removed or replaced if needed.
Why Some Patients Choose EVO ICL Over LASIK or SMILE
No removal of corneal tissue, preserving corneal integrity.
Works for extreme myopia and thin corneas.
Provides UV protection and high-definition vision.
Many patients traveling to Korea for eye surgery choose EVO ICL for its safety, reversibility, and effectiveness in treating high myopia.
