Five procedures, one pair of eyes. Here's what actually decides which one you qualify for — prescription, corneal thickness, age and tear film — and what each costs in Korea.
Most people arrive at vision correction having already picked a procedure from an ad. That is backwards. Your eyes decide which procedures are available to you, and the list is usually shorter than the menu suggests.
This guide is the decision, not the sales pitch. For the detail on any one procedure, follow the links through.
| Best for | Ruled out by | |
|---|---|---|
| LASIK | Low-to-moderate myopia, adequate corneal thickness | Thin corneas, irregular topography, severe dry eye |
| LASEK / PRK | Thinner corneas, contact-sport or military lifestyles | Very high prescriptions; slower, more uncomfortable recovery |
| SMILE | Myopia and astigmatism; no flap, less dry eye | Farsightedness; limited astigmatism range |
| ICL | High myopia, thin corneas, dry eye | Shallow anterior chamber, low endothelial cell count |
| Lens exchange | Age 45+, presbyopia, early lens changes | Under ~45 with a healthy lens |
Corneal laser procedures reshape tissue, and there is only so much to remove. Roughly: laser works well up to about −8 to −10 diopters; beyond that, ICL becomes the better answer — not the consolation prize. High myopes often get a sharper result from ICL because no tissue is removed.
Measured by pachymetry and corneal topography. Too thin, or a topography suggesting early keratoconus, and laser is off the table entirely — permanently. This is the single most common reason a confident patient is turned down, and a clinic that skips these scans is not a clinic you want.
Under 40, the question is corneal versus lens-based. Past 45, presbyopia changes it: correcting distance perfectly means reading glasses arrive immediately afterward. Many patients in their late forties are better served by lens exchange or a monovision plan than by standard LASIK — see the presbyopia guide.
A real workup takes about two hours and includes:
Stop wearing soft contacts 1–2 weeks and hard/RGP lenses 3–4 weeks before the workup, or the measurements are wrong and the plan built on them is wrong too.
| Procedure (both eyes) | United States | South Korea |
|---|---|---|
| LASIK | $4,000–$6,000 | $1,000–$2,000 |
| LASEK / PRK | $4,000–$6,000 | $1,000–$1,800 |
| SMILE | $4,000–$8,000 | $1,800–$3,000 |
| ICL | $7,000–$12,000 | $3,500–$7,000 |
| Refractive lens exchange | $8,000–$16,000 | $5,000–$9,000 |
Illustrative ranges in USD. Confirm whether enhancements and follow-up visits are included — in Korea they usually are.
Note what the table implies: cost should not pick your procedure. The spread between LASIK and SMILE in Korea is smaller than a single US LASIK bill. Choose on candidacy and lifestyle, then enjoy that all of them are affordable.
A good Korean surgeon will tell you no, and roughly one in five candidates hears it. Common reasons: corneas too thin, a topography red flag, an unstable prescription (it should be stable ~12 months), uncontrolled dry eye, pregnancy or breastfeeding, or certain autoimmune conditions.
Glasses remain an excellent outcome. Any clinic that has never turned anyone away is telling you something about itself.
Curo is a registered patient-attraction agency, not a clinic. A Korean doctor reviews your prescription and history first, so you are matched to a board-certified ophthalmologist who performs the procedure you are actually a candidate for — and you pay the clinic's own price, no foreigner markup. Booking and interpretation are free. Start with Eye Surgery & LASIK in Korea, explore vision correction, or get a free quote.

Your eyes decide, not preference. Laser procedures work well up to roughly −8 to −10 diopters with adequate corneal thickness; above that, or with thin corneas or significant dry eye, ICL is the better option. From about 45 onward, presbyopia usually makes lens exchange or a monovision plan the smarter question.
Corneas that are too thin, a topography suggesting early keratoconus, a prescription that has not been stable for about 12 months, uncontrolled dry eye, pregnancy or breastfeeding, and some autoimmune conditions. Roughly one in five candidates is turned down — a clinic that never says no is a warning sign.
For both eyes: LASIK about $1,000–$2,000, SMILE $1,800–$3,000, ICL $3,500–$7,000, and refractive lens exchange $5,000–$9,000. US equivalents run roughly three to four times higher, so cost should not decide which procedure you pick.

Somewhere in your forties, reading glasses arrive and LASIK stops being the answer. Here are the options Korean eye surgeons actually offer, what they cost, and the trade-offs nobody mentions.
Cataract surgery in Korea pairs high surgical volume with premium lens options — at a fraction of US self-pay prices. Here's what US patients should know about lenses, cost, and recovery.
If your prescription is too high or your corneas too thin for LASIK, ICL may be the answer. Here's how implantable-lens surgery in Korea works — candidacy, cost, and recovery — for US patients.
