Laser vision correction
Reviews are right that glare, halos and dry eye can follow SMILE. They mislead when early weeks are read as the final result: these effects usually fade within weeks, and vision settles over 1β3 months.
Reading Korea SMILE LASIK side effects reviews and wondering whether the dry eye and night halos people describe will follow you home?
Read this before you book a flight or rule the surgery out.
You'll know which review claims hold up medically, what decides the cost, which methods suit which eyes, and how recovery usually goes, so you can weigh SMILE against your own eyes and budget.
Hello, I'm Dr. Hyun Chul Cheon, Representative Director at Bright Eye Clinic Gangnam. I'm an ophthalmology specialist, and my published record lists 140,000 vision correction cases, 50,000 of them SMILE.
The clinic has 3 VisuMax lasers on site and interpreters for international patients. It is KAHF accredited for 2025β2029, under Korea's program for hospitals serving foreign patients.
I wrote this because a review describes one person's first weeks, and readers often take it as a forecast for their own eyes.
Most reviews are right that glare, halos and dry eye can follow SMILE. They mislead when they treat the early weeks as the final result: these effects usually fade within a few weeks, and vision settles over 1β3 months.
If one review has stuck in your mind, send a photo of your latest glasses prescription on WhatsApp and name the side effect that worries you most. Your first question is then about your numbers rather than a stranger's.
Partly. Dry eye in the early weeks is real, and SMILE doesn't remove the risk. What reviews tend to leave out is why it differs so much from one person to the next.
SMILE takes out a small disc of tissue, called a lenticule, through a small incision, with no flap. In a 2014 review in Eye and Vision, corneal sensation and nerve findings generally favored SMILE over LASIK in the first months. The same paper notes that dryness scores worsened early after both operations in one study, and its authors think SMILE is unlikely to eliminate dry eye, because other factors feed into it.
Those other factors are the part a review can't show you: years in contact lenses, hours at a screen, how the eye behaved before surgery. When dryness does appear, it can usually be managed with artificial tears or prescribed medication.
When I read a dry-eye complaint, my first question is how those eyes felt before the operation. Someone whose lenses already burn by evening starts from a different place than someone who has never noticed their tears. So I'd treat your own evening dryness as more useful information than any thread. Tell your doctor about it plainly, because your lifestyle and visual needs belong in the decision alongside the measurements.
Dr. Hyun Chul Cheon
In the first weeks, usually not. Glare and nighttime halos are among the temporary effects we list after SMILE, and they typically improve within 1β2 weeks, sometimes taking a few weeks to settle.
So a review written in week one and describing halos around every streetlight is probably accurate about that week. It tells you little about month three. Some people do notice night glare for longer, so if you drive after dark for work, raise it before surgery rather than after.
One more thing worth separating: glare that was already there before any surgery. In an older eye, a clouding natural lens can be the cause, and no corneal procedure treats that. If this sounds like you, choosing a lens for cataract surgery may be the more relevant conversation.
Vision may be slightly blurry on the day of surgery, and most people see clearly from the next day. Glare, halos and dryness typically ease within 1β2 weeks, and final results come within 1β3 months.
Reviews sometimes claim SMILE is sharper the next morning than any other laser option. The evidence doesn't support that. The review paper above describes slightly slower visual recovery with SMILE compared with LASIK as its current disadvantage, while noting that laser setting changes have improved this. If your first morning is a little soft, that alone doesn't mean anything has failed.
A second common claim is that the prescription always creeps back. Vision can drop after surgery, and when it does, the usual explanations are myopic regression or dry eye, with dry eye the more common of the two. Dry-eye blur can usually be improved with care. If regression is the cause, enhancement options such as LASEK or ICL may be considered, and how much corneal tissue remains is what limits them.
Fear of blinking at the wrong second comes up in almost every thread. A lid speculum holds the eye open, so blinking isn't something you have to control. Eye movement is involuntary, which is why VisuMax systems use eye fixation.
The real event behind the horror stories is losing that fixation, known in the literature as suction loss. One series in the same review reported it in 14 eyes, or 0.8%. It is uncommon, and it has a plan: the surgeon decides whether to continue safely or convert to another method such as LASEK. I'd rather you know that exists than read about it at midnight on a forum.
The choice comes from measurements, and I would not assume SMILE before seeing them. Corneal thickness, how much tissue can safely be removed, endothelial cell health, eye anatomy and astigmatism all count, along with how you live and work.
Say you're at minus 7.50 with astigmatism, you've worn toric lenses for ten years, and your eyes feel dry by evening. A surgeon elsewhere told you your corneas are on the thin side. I would look first at how much tissue the correction needs and what would remain. If that margin looks comfortable, SMILE stays on the table. If it doesn't, removing more tissue is the wrong trade, and I'd move to another option.
Here are the methods we offer for that conversation:
The trade-offs among the laser options are laid out in how SMILE, LASIK and LASEK compare. If your cornea points you away from laser, read what counts for EVO ICL surgery next.
Common and temporary. Glare, nighttime halos and dryness, usually resolving within a few weeks.
Less common. Slower visual recovery or a small remaining prescription, which may lead to an enhancement.
Rare but serious. Corneal inflammation or opacity. These are typically treatable with medication when caught early, which is why new symptoms shouldn't sit for days.
As general guidance, these situations are reasons to hold off or think again:
If pain, sudden blur or increasing redness appears after you fly home, see a local eye doctor promptly and bring your surgical records. The CDC's medical tourism page advises getting copies of all your records before leaving and warns that complications may need treatment back home, possibly at your own expense. Results differ between people, so read every figure here as typical rather than as a promise.
If you wear contact lenses, add your lens type and how many years you've worn them to your WhatsApp message, and ask whether that history changes your options.
Send your prescription and one question on WhatsApp
The clinic doesn't publish a price list, so I can tell you what moves the figure rather than the figure itself. These are the main factors:
If you're also weighing a flap procedure, what moves the cost of LASIK covers that side. For your own figure, ask on WhatsApp what it would cost for your case, and name the procedure you have in mind.
Reviews can tell you what to ask. They can't tell you what your cornea will do, because they never measured it.
A single prescription photo is enough to start on WhatsApp, along with the sentence from a review that bothers you most, and you can ask before booking anything. When you do come in, the doctor examines your eyes and recommends the option that fits them.
Results vary by individual, and your exam decides which procedure is proposed.
Cataract and presbyopia
For cataract surgery in Korea, the cost is shaped mainly by the lens implanted, whether one or both eyes are treated, extra measurements your eye history calls for, and your follow-up days.
Laser vision correction
Three laser options, three different trade-offs. A side-by-side look at method, recovery time and who each one tends to suit, using the clinic's own comparison.
Lens surgery
EVO ICL surgery cost in Korea is set mainly by the lens type, the sizing measurements, whether both eyes are treated and your follow-up days; after about 45, compare it with presbyopia lens surgery first.
