~10 min (both eyes)
Back to daily life in 1-2 days
Picture the morning you take off your glasses and the world is already in focus — and then picture night driving without the glare and halos. Personal Custom (wavefront) LASIK maps the aberrations across your entire eye, reading the higher-order aberrations a standard prescription test misses, and designs your correction — night vision and contrast sensitivity included — for your eyes alone. More than just seeing well, it pursues crisp, clear visual quality even in dim light: a deeper layer of tailored LASIK for demanding eyes and high standards.
A personalized LASIK that analyzes higher-order aberrations, designed with night vision and contrast sensitivity in mind for a sharper outcome.
- Aberration analysis
- Night-vision optimized
- 1:1 custom design
Is it right for me?
A good fit if
- You drive at night often, or you're sensitive to glare, halos, and starbursts in the dark and care about the quality of your vision
- Your myopia and astigmatism fall within the standard LASIK range, yet detailed testing shows pronounced higher-order aberrations
- Your work demands fine, sharp vision — design, video editing, night driving — and standard LASIK alone left you wanting more
- Your cornea is stable, well-shaped, and thick enough that the flap-based LASIK approach can be applied safely
- You want one dedicated surgeon to own your exam, design, surgery, and lifetime aftercare — and precision worth traveling to Korea for
Consider carefully if
- If your cornea is thin or your prescription is very high, it may be safer to also compare flap-free SMILE or ICL (implantable lens), which doesn't reshape the cornea. We'll honestly recommend an alternative based on your exam.
- If you have severe dry eye, progressing keratoconus, are pregnant or breastfeeding, or your prescription is still changing, it's better to postpone surgery or stabilize your eyes first.
- If your eyes have little higher-order aberration, standard LASIK or LASEK may give an excellent result on their own, and we sometimes won't recommend custom design at all. Not pushing more than you need is our principle.
1What sets Custom LASIK apart from regular LASIK
Where standard LASIK corrects your myopia and astigmatism — your prescription — using a standard pattern, Custom LASIK adds your eye's own subtle higher-order aberrations on top of that. Like a fingerprint, every eye carries its own tiny refractive irregularities, so even two eyes at -3.00 diopters focus light onto the retina differently. That difference is exactly what governs glare in the dark, contrast sensitivity, and the quality of night vision. The heart of Custom LASIK is reading those individual differences as data and refining a profile made for you alone.
2The aberration map — why precision decides the outcome
Custom LASIK uses precision instruments — a wavefront analyzer and corneal topography — to measure, across hundreds of points, how light entering your eye bends and focuses on the retina. The resulting aberration map becomes the very blueprint the laser follows, so the accuracy of that measurement and the surgeon's experience in reading the data directly determine how good the outcome is. A topography-guided approach can account for fine surface irregularities of the cornea to create a smoother corrected surface. This is precisely why, with the same equipment, results differ depending on who reads the data and designs the treatment.
3What we check to keep you safe
Even with a custom design, safety ultimately rests on the exam. We carefully assess corneal thickness and shape, pupil size, tear film, the residual cornea, and any warning signs of keratoconus to first decide whether LASIK is right for you. Large pupils, in particular, are directly tied to nighttime glare, so we account for them more attentively at the design stage. If the exam shows insufficient cornea or any red flags, we won't push ahead — we'll honestly point you to safer options like SMILE or ICL. Good results, I believe, begin not with a flashy design but with an honest exam.
4Support for patients coming from overseas
Healing Eye sits one minute from Sinnonhyeon Station and is about 70 minutes from Incheon Airport, and as an MOHW-registered institution for international patients we help guide you from the moment you land. On-site interpreters in Japanese, Traditional Chinese, and English mean you can fully understand your complex aberration results and what custom design involves in your own language before deciding. We typically arrange your schedule so testing and surgery can be completed within a few days, and we keep following your progress by video call or messenger after you fly home. So that surgery in an unfamiliar country never feels daunting, we lay out the whole flow from arrival to departure in advance.
How the surgery goes
- 1
Precision aberration exam
A wavefront analyzer and corneal topography map the aberrations across your whole eye while we also check corneal thickness, pupil size, and tear film to determine if Custom LASIK fits you. This data becomes your personal blueprint.
- 2
Custom design & consultation
From your measured data, your dedicated surgeon designs a laser profile for you alone and, with an interpreter, fully explains the findings and realistic expectations in your own language. You decide once every question is answered.
- 3
Numbing drops
Just before surgery, anesthetic eye drops numb the surface of your eye. With drops only and no injection, the worry about pain is greatly eased.
- 4
Flap creation & custom laser correction
A precise laser creates and lifts a thin corneal flap, then an excimer laser corrects the cornea exactly to your pre-designed custom data. This key step is what differs most from standard LASIK.
- 5
Flap repositioning & same-day check
Once correction is done, the flap is laid back into place to adhere naturally, and both eyes are usually finished in about ten minutes. After a short rest we personally check your vision and eye condition the same day before you leave, and arrange your next visit.
Recovery timeline
For a few hours after surgery you may tear up or feel grittiness and light sensitivity, but this usually settles quickly. The most important thing today is not to rub your eyes and to rest well, wearing a protective shield while you sleep to guard the flap.
Many patients return to daily life the next day with noticeably clearer vision, and a next-day check confirms the flap has settled well and your sight is recovering. Using your prescribed drops on schedule is central to healing.
Because the design is custom, we carefully track how visual quality — night vision and contrast sensitivity — settles in. During this period, avoid saunas, swimming, eye makeup, and strong UV, and manage dryness with artificial tears.
Because the same dedicated surgeon who handled your exam, design, and surgery also follows your progress, even subtle changes in your eyes are managed by one accountable doctor. With our lifetime surgery guarantee, patients from afar can receive long-term care with peace of mind through video and messenger consultations after returning home.

Frequently Asked Questions
How is this different from regular LASIK?
While standard LASIK corrects your myopia and astigmatism with a standard pattern, Custom LASIK also accounts for your eye's unique higher-order aberrations, fine-tuning visual quality like night vision and contrast sensitivity. It isn't right for everyone, and which option suits your eyes better is something we'll honestly compare in a free LINE or WhatsApp consultation after a detailed exam.
Can it reduce nighttime glare or halos?
Because the design also corrects higher-order aberrations, it can help reduce nighttime glare and halos. That said, how much you notice depends on pupil size and eye condition, and we can't promise every halo disappears completely — so after a detailed exam we'll tell you honestly what to expect. Feel free to ask anything in a free consultation.
Does it hurt? Does testing and design take longer?
Anesthetic drops are given before surgery, so you'll feel almost no pain — at most a slight sense of pressure during the procedure. Added precision tests like aberration mapping can make the exam a little longer, but that's what enables a design tailored exactly to your eyes. The surgery itself takes about ten minutes for both eyes, and we can outline the testing schedule in advance during a free consultation.
How many days do I need to stay in Korea?
Allowing for the detailed exam, surgery, and a next-day check, we usually recommend a stay of about three to four days, which may be adjusted to your eye condition. We're right by Sinnonhyeon Station and about 70 minutes from Incheon Airport, so getting around is easy. After you fly home we keep following your progress by video and messenger, and we'll plan it all with you in advance during a free consultation.
Is it safe? Are there side effects?
LASIK is a vision-correction procedure backed by long clinical experience, but no surgery is entirely without risk. Early dry eye or temporary glare can occur and usually improves over time. That's why, before surgery, we examine corneal thickness, shape, pupil, and tear film closely and recommend it only to those it suits — and if the cornea isn't sufficient, we'll honestly point you to safer options like SMILE or ICL. Start by checking whether it fits your eyes in a free consultation.
How much does it cost, and do foreigners pay more?
International patients pay exactly the same price as Korean patients, with no tourist markup at all. That said, Custom LASIK costs vary with your exam results and the scope of design, so a single flat figure isn't really possible. After a detailed exam, we'll give you a precise, transparent quote in a free LINE or WhatsApp consultation — please feel free to reach out.
