Dr. Nattawut Wanumkarng

Dr. Nattawut Wanumkarng (Thai: นพ. ณัฐวุฒิ วะน้ำค้าง) is an ophthalmologist in Bangkok whose surgical field is oculoplastic and reconstructive surgery: operations on the eyelids, the eyebrow region directly above them, the tear-drainage passages and the orbit (the bony cavity around the eyeball). Bumrungrad International Hospital lists him in its Eye Center under two specialty labels, Comprehensive Ophthalmology and Oculoplastic & Reconstructive Surgery. He also works at At Eye Clinic (ณตา จักษุคลินิก), a private eye clinic in Chatuchak whose earlier website describes him as its founder and director and as an oculo-facial plastic surgeon.

His route into cosmetic eyelid work runs through eye medicine rather than general plastic surgery. He qualified in medicine at Siriraj Hospital, Mahidol University, trained there as an ophthalmology resident, earned the Thai Board of Ophthalmology diploma, then spent 2003–2004 at the University of California, San Diego, as a clinical fellow in orbital and ophthalmic plastic surgery. For a patient comparing surgeons, that places Dr. Nattawut as an eye surgeon who concentrates on the structures around the eye. None of his published profiles mention breast, body or nose operations, so he is not the surgeon to approach for those.

Procedure areas we list for Dr. Nattawut Wanumkarng, each tied to an official source:

• Blepharoplasty (eyelid surgery): “Functional and Cosmetic Eyelid Surgery” is a special clinical interest on his Bumrungrad profile and appears under “Expertise and Experience” on his At Eye Clinic profile.
• Ptosis correction: the one service his At Eye Clinic profile names is Mullerlectomy, which the clinic describes as surgery for a drooping eyelid.
• Brow lift: endoscopic eyebrow lift is listed among his endoscopic operations at At Eye Clinic and among his special clinical trainings at Bumrungrad.
• Double eyelid surgery: he wrote Bumrungrad's Thai-language patient article on double-eyelid surgery by the hospital's eyelid-specialist ophthalmologists.

Alongside these cosmetic and functional eyelid procedures, his published interests include tear-duct (lacrimal) surgery, orbital tumours and orbital surgery, reconstruction after eyelid and orbital injuries, orbital decompression for thyroid eye disease, and intense pulsed light (IPL) treatment for dry eyes. According to his Bumrungrad profile, he consults in Thai and English.

If one of these eyelid or brow concerns is bringing you to Bangkok, send a consultation request for Dr. Nattawut Wanumkarng. Our patient team checks his availability with Bumrungrad or At Eye Clinic and normally replies within one working day; your date is fixed only when our confirmation reaches you.

Each step below is taken from his Bumrungrad and At Eye Clinic profiles or from the ophthalmology college's directory; where two sources differ slightly, we give both.

• M.D., 1996: Mahidol University, at its Faculty of Medicine Siriraj Hospital. The Thai-language Bumrungrad profile records the year as 2539 in the Thai Buddhist calendar, which is 1996; the clinic's older website gives the study period as 1991 to 1996.
• Ophthalmology residency, 1999 to 2002: Siriraj Hospital, Mahidol University, Bangkok, as published on At Eye Clinic's older website.
• Diploma of the Thai Board of Ophthalmology, 2002: recorded on the Thai Bumrungrad profile as a วุฒิบัตร (board diploma) in ophthalmology, dated 2545 (2002). The clinic's older site uses the wording “Diplomate of Thai Board of Ophthalmology”.
• Fellowship in orbital and ophthalmic plastic and reconstructive surgery, 2003 to 2004: University of California, San Diego. The clinic's older site places this clinical fellowship at the Shiley Eye Center, Department of Ophthalmology, UC San Diego School of Medicine, and an archived Royal College directory entry records it as oculoplastic and reconstructive surgery, Siriraj–Shiley Eye Center–UCSD.
• Special clinical trainings: Bumrungrad lists endoscopic dacryocystorhinostomy (a tear-duct operation), endoscopic eyebrow lift, and orbital decompression surgery for thyroid eye disease. The profile does not say where or when this training took place.

What the sequence tells a patient. His path runs from a general medical degree, to specialist training and a national board qualification in ophthalmology, to a fellowship devoted to the eyelids and orbit, the subspecialty known internationally as oculoplastic or oculofacial plastic surgery. That is a different route from the one taken by plastic surgeons, who train in general and plastic surgery and operate across the whole body. Neither route is automatically better for eyelid surgery; what matters is that the surgeon's training covers the operation you need, and for Dr. Nattawut the documented training centres on the eye region.

Society and college listings. Three pages published by ThaiSOPRS (Thai Society of Ophthalmic Plastic & Reconstructive Surgery) carry his name: the public member directory; the Leadership page, where he is Chair of International Relations; and the Founding Members page, which places him on the academic committee. In the public doctor search run by RCOPT, the Royal College of Ophthalmologists of Thailand, his entry records oculoplastic and reconstructive surgery as his field of interest and Bangkok as his location, without stating a membership class or year. His name is absent from the member list of ThPRS (the plastic surgeons' society), which we went through page by page on 27 September 2026. For a doctor who reached eyelid surgery through ophthalmology rather than general surgery, that is what you would expect: the eyelid-and-orbit society named above is the body that matches his field.

Medical licence number. Medical License 21746 is printed on his At Eye Clinic profile and again on the clinic's team page. The number appears here as the clinic publishes it; it can be looked up on the Medical Council of Thailand's public register at checkmd.tmc.or.th. You can repeat the search on the Council's register yourself, or ask to see the licence at your appointment.

Not publicly documented. No academic title appears on any source we opened, and no source states how many eyelid, ptosis or brow operations he has performed. Our provider research methodology page explains the sources we rely on and the reasons.

Bumrungrad International Hospital, Eye Center. Bumrungrad lists Dr. Nattawut as an ophthalmologist on the Eye Center roster (18th floor, Building A), carrying two labels there, Oculoplastic & Reconstructive Surgery plus Comprehensive Ophthalmology. His published Eye Center hours, as of our 27 September 2026 check, were Monday, Wednesday, Thursday and Friday 09:00–11:30 and 13:00–15:00, and Tuesday 09:00–12:00. Because the hospital can change these sessions, a date is fixed only after our patient team has agreed it with Bumrungrad. Note that his listing sits with the Eye Center rather than with the hospital's Plastic (Cosmetic) Surgery Center, so the Eye Center is where his appointments are arranged. Our Bumrungrad International Hospital profile covers the hospital itself.

At Eye Clinic (ณตา จักษุคลินิก), Chatuchak. The clinic's address is 9/99 Ratchadaphisek 33 Alley, Lat Yao, Chatuchak, Bangkok 10900. Its current website lists Dr. Nattawut first under “Our Team”, with the position “Surgeon” and Mullerlectomy as his service; the clinic's earlier, Wix-hosted website calls him its founder and director. The current site shows clinic opening hours of 9.00 to 20.00, but those are the clinic's hours rather than his personal sessions, and the doctor schedule on the older site may be out of date. We do not yet have a separate profile page for At Eye Clinic, and we have not documented its facilities, operating arrangements or accreditation.

ThaiSOPRS roles. On the eyelid-and-orbit society's Leadership page he is Chair of International Relations within the executive committee. Its Founding Members page lists him on the academic committee (คณะกรรมการวิชาการ).

Patient articles and research. Bumrungrad's Thai-language health blog carries articles credited to him, including a June 2020 piece on double-eyelid surgery at the hospital and two 2017 pieces on drooping upper eyelids and blepharoplasty. The hospital's bylines describe him as an ophthalmologist working in plastic and reconstructive surgery around the eye and in the tear-drainage system at its Eye Center. Other articles and a hospital podcast episode credited to him cover blocked tear ducts and endoscopic dacryocystorhinostomy, problems of the orbit, orbital fractures, dry eye, IPL and eyelid spa care.

On PubMed, a 2023 case report in *Frontiers in Ophthalmology* on ocular intense pulsed light and the eyelash microbiome in severe meibomian gland dysfunction lists his affiliation as the Department of Ophthalmology at Bumrungrad International Hospital. Two older papers from Siriraj's ophthalmology department, on eye disease and blindness in elderly Thais (2001) and on electrodiagnostic testing in nonsyndromic microcephaly (2003), carry the author name “N Wanumkarng” without a personal affiliation. They date from around his Siriraj training years and are likely his, though the records cannot confirm it.

Not publicly documented: the year he joined Bumrungrad, the year At Eye Clinic was founded, and any count of patients treated or operations performed.

The four procedures below are the ones we can link to Dr. Nattawut through official sources. The general points under each come from our procedure guides and apply to eyelid and brow surgery broadly; your own plan depends on his examination.

1. Blepharoplasty: functional and cosmetic eyelid surgery

The phrase “Functional and Cosmetic Eyelid Surgery” appears in the special-interest section of his Bumrungrad profile and again under his expertise at At Eye Clinic. The pairing of the two words is worth noticing. Our blepharoplasty guide describes the operation as taking away or repositioning surplus skin, muscle and fat on the upper eyelids, the lower eyelids, or all four lids. Where drooping upper lids have narrowed the field of view, the same surgery can also help sight, which is the functional half of his listed interest. Thai-language articles he wrote for Bumrungrad in 2017 cover drooping upper eyelids and blepharoplasty, treating sagging lids as an eye problem that can be corrected.

Points to raise when you consult him about eyelid surgery:

• On the upper lid, the scar is normally placed in the existing fold. The lower lid can be approached through a fine cut just under the lash line, or through the lid's inner lining (the transconjunctival route), which leaves no mark on the skin. Our guides to upper eyelid surgery and lower eyelid surgery set out the difference. His profiles do not say which lids or approaches he prefers, so ask him.
• As an eye specialist, he will want to know about your eyesight and about conditions such as glaucoma, thyroid eye disease or a tendency to dry eyes, since each of these can change whether, or how, eyelid surgery is done.
• According to our blepharoplasty guide, the operation is commonly performed either with sedation plus local anaesthetic or with a general anaesthetic, normally as a day case, and takes about 1–2 hours in theatre.

2. Ptosis correction: Mullerlectomy

The only service named on his At Eye Clinic profile is Mullerlectomy, which the clinic describes as a surgical procedure used to treat ptosis, a drooping eyelid. Ptosis is not the same as loose eyelid skin: the lid margin itself sits too low, and correcting it generally involves the muscles that raise the lid rather than simply removing skin. A person can have excess skin, ptosis or both, which is one reason an examination by an eyelid specialist matters before choosing an operation. Mullerlectomy is the one ptosis technique his profile names; whether it suits your eyelid, or whether a different repair is needed, is decided after he has examined the lid. As general guidance, our ptosis correction page treats 5–7 days in Thailand as a typical trip, with the surgeon deciding when you can fly.

3. Brow lift: endoscopic eyebrow lift

At Eye Clinic lists endoscopic eyebrow lift among Dr. Nattawut's endoscopic operations, and Bumrungrad records it among his special clinical trainings. Endoscopic means the surgeon works with a small camera and instruments passed through short incisions. The brow belongs in an eyelid conversation because heaviness above the eye does not always come from the lid. If the eyebrow has sagged, trimming lid skin alone will not raise it, which is why a brow lift is sometimes recommended instead of, or together with, eyelid surgery. Ask him whether your heaviness comes from the lid, the brow or both, and where the incisions for his approach would sit. For a brow lift, our general guidance is a longer trip, typically 7–10 days in Thailand.

4. Double eyelid surgery

Our listing rests on a Thai-language article Dr. Nattawut wrote for Bumrungrad in June 2020 about double eyelid surgery performed by the hospital's eyelid-specialist ophthalmologists; the article states that the ophthalmologists of the hospital's eyelid centre have experience with the operation. We found no service list that names him for double-eyelid surgery directly, so ask at your consultation whether he performs it himself and which technique he would use. Our eyelid guide describes two general ways of forming an upper-lid fold: an incisional method, and, where the lid is suitable, a suture (non-incisional) method whose result may not last as long. Whichever is used, a newly made fold often looks high in the early weeks and settles over the months that follow.

Eye-area problems outside our procedure list

His published work also covers conditions that are medical or reconstructive rather than cosmetic: tear-duct (lacrimal) surgery including endoscopic dacryocystorhinostomy, orbital tumours and orbital surgery, reconstruction after eyelid and orbital trauma, orbital decompression for thyroid eye disease, and IPL treatment for dry eyes. We do not publish guides for these, and published sources do not say which of them are offered at which of his two locations. You can still describe the problem in a consultation request, and our team will ask the hospital or clinic whether an appointment can be arranged. A recent injury around the eye or a sudden change in vision needs prompt local medical care rather than a travel booking.

At Eye Clinic's website lists further eyelid services, such as baggy eyelid surgery, subbrow blepharoplasty and entropion and ectropion repair, but those service pages do not name a surgeon, so we do not attribute them to Dr. Nattawut.

Patients often arrive at an eyelid consultation with a broad complaint, such as tired-looking eyes, heavy lids or one eye looking smaller than the other, and the first job of the appointment is to find which structure is responsible. Because Dr. Nattawut's documented work spans the eyelid skin, the muscle that lifts the lid and the brow, that sorting-out is the most useful thing a first visit with him can achieve.

What is usually covered

• Your concern in your own words, which side it affects and how long it has been present.
• Your eyes so far: how well you see, any glaucoma or thyroid eye disease, dryness or irritation, and past operations on the eyes or lids.
• Your general health, medicines and allergies, which bear on anaesthesia and on the risk of bleeding.
• An examination of the eyelids and brows. The plan, and any estimate, depends on this in-person assessment.

Questions worth asking Dr. Nattawut

• Which part is causing the heaviness I notice: loose skin, a lid edge that sits too low (ptosis), a dropped brow, or more than one of these?
• If I have ptosis, is Mullerlectomy suitable for my eyelid, or would a different repair be needed?
• For a brow concern, is an endoscopic brow lift suitable for me, and where would the incisions be?
• If I want a double-eyelid fold, will you operate yourself, and do you favour an incisional or a stitch-based technique for lids like mine?
• Where would the operation happen, Bumrungrad or At Eye Clinic, and would I be sedated with a local anaesthetic or fully asleep?
• When are stitches removed, when may I fly, and which doctor handles any complication after I have flown home?
• What does the estimate include, and what could change it? Upper, lower or both lids, the technique, the anaesthesia and any combined procedure all affect the price; our cost guides explain the main factors.

Risks to talk through

Our eyelid guide lists the complications to discuss, in general terms: eyes that feel dry or gritty, a spell of blurred vision, trouble shutting the lids completely, the two sides healing unevenly, noticeable scars, a lower lid that pulls away or down, infection, and, as a very rare event, bleeding behind the eye that threatens sight. Ask Dr. Nattawut how his team lowers each of these risks and what would be done if one occurred. Treat sudden, severe eye pain or any drop in vision after surgery as an emergency.

Online first, or in person?

Let our team know if you prefer a first contact online or would rather meet him in person. Photos can support a first conversation, but a surgical plan depends on examination, so anything prepared before that is provisional. We have not found a published statement on whether Dr. Nattawut offers video consultations himself; our team confirms the options with the hospital or clinic when you send your request.

Bumrungrad International Hospital (on Soi Nana Nua, 33 Sukhumvit 3, Wattana). What the hospital publishes for patients travelling from abroad, set out stage by stage:

• Before travel. Coordinating doctors and nurses in the hospital's free Medical Coordination Office (10th floor, Building A) can review your records, give estimated prices, set up appointments or telemedicine, and deal with insurers, embassies and medical transport. The same office stays involved while you are in Bangkok and, after discharge, handles medical reports, fitness-to-fly letters and follow-up.
• Arriving. A Bumrungrad representative counter sits in the international arrivals area at Suvarnabhumi (Exit C, Gate 9) and opens 07.00–23.00 daily. From the airport, a complimentary van heads to the hospital, or to hotels in its neighbourhood, at roughly hourly intervals, subject to passenger numbers.
• Getting around. Complimentary hospital vans link BTS Nana and BTS Phrom Phong stations with the hospital every day of the week.
• Language. Bumrungrad's factsheet counts over 130 interpreters. For patients whose first choice is not English, the hospital also has Cultural Support Officers and Cultural Helpdesks.
• Paperwork and bookings. Visa extensions for patients and companions are coordinated through the hospital's Business Center with the Bangkok Immigration Office, and the same desk handles hotel and air-ticket bookings.

On accreditation, the JCI directory shows Bumrungrad as accredited since February 2002, its HA Thailand Advanced Hospital Accreditation runs to May 2029, and Global Healthcare Accreditation recognises it for medical travel. Sources for each are on our Bumrungrad profile.

At Eye Clinic is a private eye clinic in Chatuchak, on Ratchadaphisek 33 Alley in Lat Yao. We have not found published information about services for overseas patients there, such as interpreters, transfers or accreditation, so plan your own transport and ask our team to confirm the exact location and whether your consultation or any surgery would take place at the clinic or at Bumrungrad.

How long to stay. Our procedure pages give typical trip lengths as general guidance: 5–7 days in Thailand for ptosis correction, blepharoplasty or a double-eyelid procedure, and 7–10 days for a brow lift. For eyelid surgery, the blepharoplasty guide puts stitch removal at around 5–7 days and says most bruising settles within 1–2 weeks. Healing differs between people, so book a flexible return ticket and let Dr. Nattawut confirm when you are fit to fly.

Packing and flying. Pack sunglasses for glare and for the journey home. Keep away from pools and eye make-up until the surgeon clears you, and ask his team which drops to use, and how often, while you are on the plane.

Language. Dr. Nattawut's Bumrungrad profile gives Thai and English. Patients who need a different language can ask us to request a hospital interpreter when we arrange the appointment. We have no published information about interpreters at At Eye Clinic.

A concise, specific request lets Dr. Nattawut's team judge whether starting online makes sense and what to examine when you arrive. Medical information should reach us only via our booking form or the WhatsApp line on this site, and photos only once his team requests them.

Useful in every request

• The concern, which eye or eyes it affects, and when you first noticed it.
• Whether heavy or drooping lids affect your sight, for example when reading or driving.
• Eye conditions and past treatment: for example thyroid eye disease, glaucoma or dryness, earlier operations on the eyes or lids, and a recent eye-test report or glasses prescription if you have one.
• General health conditions, the medicines you take regularly, and any allergies.
• Reports from any earlier surgery on the eyelids or brows, naming the operation and when it was done.
• Your travel window and preferred location, Bumrungrad or At Eye Clinic.
• The questions you want to ask Dr. Nattawut.

If the team asks for photos

• Your face straight on, in even daylight, without make-up, glasses or false lashes, eyes open and looking ahead with the camera at eye level.
• A matching photo taken with your eyes softly shut.
• For a brow concern, the forehead relaxed, then with the brows raised.
• For a drooping-lid concern, a close-up of both eyes at eye level while you look straight ahead.
• Older photos showing how your eyelids looked in earlier years, if you have them; they help show what has changed.

Keep the original files rather than screenshots, and do not apply filters or beauty modes, which can hide the very folds and asymmetries the surgeon needs to see.
