Assoc. Prof. Dr. Preamjit Saonanon

Assoc. Prof. Dr. Preamjit Saonanon (Thai: รศ.พญ.เปรมจิต เศาณานนท์) is a Bangkok oculoplastic surgeon, meaning an eye doctor who went on to subspecialise in plastic and reconstructive operations on the eyelids and the tissues that surround the eye. She holds the rank of Associate Professor in ophthalmology at Chulalongkorn University's Faculty of Medicine, and the Chulalongkorn Eye Center names her as head of its oculoplastic and reconstructive surgery unit, whose clinics run at King Chulalongkorn Memorial Hospital. Her private work takes place at Saonanon Clinic (เศาณานนท์คลินิก), which she runs on Soi Thonglor 25 in Watthana; the clinic says she consults and operates there by appointment.

Everything documented about her practice concerns the eyelids. On her personal website, the areas of expertise are double eyelid surgery, revision of an earlier double eyelid operation, ptosis correction (both the age-related and the congenital kind), lower blepharoplasty, epicanthoplasty, and eyelid changes caused by thyroid eye disease. Saonanon Clinic's own pages add an operation for the loose, hooded upper-lid skin of older patients. On this site those services correspond to five pages: double eyelid surgery (including revisions), ptosis correction for drooping lids, upper eyelid surgery for hooding, lower eyelid surgery for bags beneath the eyes, plus the broader blepharoplasty overview.

Her route into eyelid surgery ran through ophthalmology rather than general plastic surgery, and that shows in where she is registered: the ophthalmic plastic surgery society ThaiSOPRS, plus the Royal College of Ophthalmologists of Thailand, both described in the training section below. The official pages we reviewed describe eyelid procedures only, with nothing on noses, breasts, body contouring or facelifts, so if you hope to combine eyelid surgery with other cosmetic operations, you may need a separate surgeon for those parts of the plan.

If you would like to see her, from within Thailand or from abroad, our patient team forwards your consultation request. The team checks availability with the clinic or the hospital first, and nothing is fixed until that side confirms.

The training record below comes from her Chulalongkorn Eye Center profile and her personal website. It follows the usual Thai route from medical school to ophthalmology and then to an eyelid and orbit subspecialty:

• Medical degree: a Doctor of Medicine degree (แพทยศาสตรบัณฑิต) from Chulalongkorn University; her website adds that she graduated with first-class honours.
• Ophthalmology board: a Thai Board of Ophthalmology diploma (วุฒิบัตร); this qualification certifies specialist knowledge and competence in ophthalmology. Her website calls her a Diplomate of that board and names the Royal College of Ophthalmologists of Thailand as the awarding body.
• Oculoplastic subspecialty: certification in oculoplastic and reconstructive ophthalmology (จักษุวิทยาตกแต่งและเสริมสร้าง), which her website also credits to the Royal College.
• Overseas fellowship: her Eye Center profile records a research fellowship in oculoplastic and reconstructive surgery at the University of California San Diego (UCSD). The English version of her website calls this further fellowship training at UCSD, while the Thai version describes it as a further period of study there.

Both her website and the clinic mention time spent training alongside oculoplastic surgeons in the United States, Korea, China and Japan. Because neither names the hospitals or universities involved, UCSD is the only overseas post we list.

None of these qualifications carries a published year, so we do not say how many years she has practised. The clinic can answer that if it matters to your decision.

Society and college listings. ThaiSOPRS, the Thai Society of Ophthalmic Plastic and Reconstructive Surgery, includes her in its online member directory, although that entry still shows her former rank of Assistant Professor. The Faculty of Medicine, the Eye Center and her website all give Associate Professor, which is the title used on this page. In the Royal College's 'find an ophthalmologist' search she appears twice, and one of the two entries records oculoplastic and reconstructive surgery as her field of interest.

Licence. No official page we found prints her licence number; it can be looked up on the Medical Council of Thailand's public register at checkmd.tmc.or.th. You can run the same search yourself before surgery, as you would for any surgeon; how we check each fact, and where it comes from, is explained in our provider research methodology.

Official pages list three current positions for her:

• Associate Professor in ophthalmology at Chulalongkorn University's Faculty of Medicine, with an office on the 16th floor of the Rattanawittayaphat Building.
• Head, Oculoplastic and Reconstructive Surgery Unit (หน่วยจักษุตกแต่งและเสริมสร้าง) in the Chulalongkorn Eye Center's ophthalmology department, which is based at King Chulalongkorn Memorial Hospital. The hospital's own doctor list also names her under ophthalmology.
• Surgeon in charge of Saonanon Clinic in Thonglor; the clinic states that it is run by her.

According to its own page, the unit she leads looks after eyelid conditions such as blepharoptosis (a drooping upper lid) and dermatochalasis (surplus eyelid skin), together with lacrimal (tear-duct) problems, disorders of the orbit and artificial eyes.

An April 2026 archive copy of her Eye Center profile shows three weekly hospital sessions: general ophthalmology on Monday mornings, the oculoplastic and reconstructive clinic on Monday afternoons, and, on Wednesday mornings, a clinic that combines thyroid-related eye problems with prosthetic eyes. The live Eye Center website was down when we checked in September 2026, so treat that timetable as background rather than a guide to booking.

Research. Searching PubMed by her surname returns 19 records, and every one that states an affiliation gives Chulalongkorn. The eight chosen for this profile mirror her clinical interests:

• Ptosis surgery: a randomised clinical trial comparing external levator advancement with Müller muscle–conjunctival resection for aponeurotic, or age-related, ptosis (Plastic and Reconstructive Surgery, 2018).
• Asian eyelid anatomy: an ultrasound biomicroscopy comparison of single and double eyelids in Asian patients (Asia-Pacific Journal of Ophthalmology, 2016), an update on Asian eyelid anatomy and why it matters clinically (Current Opinion in Ophthalmology, 2014), and a review titled 'The new focus on epicanthoplasty for Asian eyelids' (Current Opinion in Ophthalmology, 2016).
• Thyroid eye disease: Müller's muscle–conjunctiva resection on the opposite lid as an option when thyroid eye disease retracts one eyelid only (Orbit, 2020), and a randomised controlled trial of selenium supplements for inactive moderate-to-severe Graves' orbitopathy (Orbit, 2024).
• Reconstruction: a newly designed gold weight placed above the tarsal plate, compared with the traditional pretarsal model, for long-standing paralytic lagophthalmos, in which the lid cannot close after facial nerve paralysis (Archives of Plastic Surgery, 2024); and a titanium mesh implant designed for the individual patient to rebuild complex orbital fractures (Plastic and Reconstructive Surgery Global Open, 2022).

Her website also lists a Thai-language textbook she wrote on eyelid surgery for appearance and for disease (การผ่าตัดเปลือกตาเพื่อความสวยงามและรักษาโรค, 2015), and Saonanon Clinic credits her with a book called 'Techniques in Aesthetic and Functional Eyelid Surgery'. Papers and books show what she studies and teaches; the services she offers private patients are the ones set out in the next section.

Each procedure below is named on her personal website or on Saonanon Clinic's pages. Where a paragraph gives general information, it is drawn from our procedure pages and applies to eyelid surgery broadly; what is right for your own eyes depends on her examination.

Double eyelid surgery (Asian blepharoplasty). This heads the expertise list on her website, and the clinic's services page says she performs it through either a small incision or a full, longer incision. In general, the aim is an upper-lid crease: a new one where the lid has none, or a reshaped one where it does. With a full incision the scar lies in the planned crease; the suture, or non-incisional, method suits only some lids and may not last as long. Which approach fits your lid and eye shape is a question for her examination. Patients often ask about crease height and whether the result will look natural; as a general rule a new crease looks higher at first and relaxes over the following months, so photos from the first weeks do not show the final result. Her ultrasound study of single and double Asian eyelids deals directly with the anatomy behind these choices. More on double eyelid surgery in Thailand.

Revision double eyelid surgery. Both her website and the clinic offer correction of an earlier double eyelid operation. A crease that ended up too high, came out uneven or has faded needs a different plan from a first operation, and she will want to know exactly what was done before, so gather operation notes and any photos you have. We have no separate revision page; the topic is covered within double eyelid surgery.

Epicanthoplasty. Her website lists it, and it is the subject of her 2016 review. The operation alters the epicanthal fold, the small fold of skin covering the inner corner of the eye, and some patients consider it together with a double eyelid procedure. Because this site has no epicanthoplasty page, add it to your consultation request if you would like it discussed.

Ptosis correction. Ptosis means the upper lid's edge sits lower than it should. That is a different problem from a fold of excess skin: the fix involves the lid-lifting muscle rather than the skin, which is why it has to be ruled in or out before any eyelid operation is planned. Her website covers both age-related and congenital ptosis, and the Chulalongkorn unit she heads lists blepharoptosis among the conditions it treats. Since her 2018 trial compared two established operations for age-related ptosis, it is reasonable to ask which of them she would choose for you, and why. More on ptosis correction.

Upper eyelid surgery for excess skin. Saonanon Clinic lists upper blepharoplasty for dermatochalasis, the slack, hooded upper-lid skin that develops with age, and its services page names her for it. In general, the scar sits in the natural lid crease, surplus skin (and sometimes fat) is removed, and heavy lids that were blocking the top of the visual field may improve. Sometimes the real cause of hooding is a brow that has dropped, and our eyelid surgery guide says a brow lift can then be the more suitable operation. Brow lifting does not appear in her documented work, so it is worth asking her to assess your brow position and explain whether it changes the plan. More on upper eyelid surgery.

Lower eyelid surgery for under-eye bags. Her website lists lower blepharoplasty for bags and excess fat under the eyes, and the clinic describes two routes: through the skin (transcutaneous) and from the inner surface of the lid (transconjunctival). In general, lower-lid surgery removes or repositions the fat pads and can tighten skin; an incision just beneath the lashes gives access to the skin, while the inside route leaves no visible scar. The better route depends on whether your concern is mainly fat, mainly loose skin, or both. One recognised risk is lower-lid malposition, where the lid is pulled downward, so ask how she assesses lid support before operating. More on lower eyelid surgery and our wider blepharoplasty guide.

Eyelid problems from thyroid eye disease. Eyelid abnormalities caused by thyroid eye disease, such as an upper lid retracted too high, are on her website's expertise list, and her archived Chulalongkorn profile shows a weekly clinic for thyroid-related eye disorders. This is reconstructive and medical work rather than cosmetic surgery, and no procedure page on our site covers it. If you have thyroid eye disease, include it in your request even when you are enquiring about a cosmetic operation, because it affects how safely eyelid surgery can be planned.

Expect an eyelid consultation to combine an eye examination with planning. In general the surgeon checks where each lid margin sits, whether the eyes close fully, how much loose skin and fat there is, the position of the brows and the condition of the eye surface. Because they bear on safety, you will be asked about your vision, any glaucoma or dry eye, and thyroid eye disease.

Questions that match Dr. Saonanon's documented procedures:

• Is my main problem surplus skin, a low lid margin (ptosis), puffiness under the eyes, or a mix? The answer decides between blepharoplasty, ptosis repair or both.
• For a double eyelid: small incision or full incision for my lids, and what crease height suits my eyes?
• For a revision: how much can be changed after my earlier operation, and should I wait longer before another one?
• For ptosis: which of the established operations would you use, and how will you match the two sides?
• For under-eye bags: inside the lid or through the skin, and why in my case?
• Would epicanthoplasty help with what I want, or is it unnecessary?
• Will the operation be at Saonanon Clinic or at the hospital, and under what anaesthesia? In general, eyelid surgery is performed with local anaesthesia plus sedation or with a general anaesthetic, lasts roughly 1–2 hours and does not usually need an overnight stay.
• Who takes out the stitches, and when can I fly?
• Should something need checking once I am back home, how is follow-up arranged?

Our blepharoplasty guide suggests confirming any surgeon's licence and specialist training, asking how many eyelid operations they carry out, and asking how complications are managed once you have left Thailand. Her training is set out above; she has not published case numbers, so ask her if that figure matters to you.

This profile does not give prices for Dr. Saonanon. The general factors behind eyelid surgery costs (which lids are treated, the double eyelid technique, the anaesthesia and any combined operations) are explained on our blepharoplasty page; once a plan is agreed, ask the clinic for a written quote.

Dr. Saonanon's two workplaces are in different parts of Bangkok and serve different purposes.

Saonanon Clinic, Thonglor. The clinic's address is 34 Soi Thonglor 25, Sukhumvit 55 Road, Watthana, Bangkok 10110, behind Camillian Hospital according to the clinic; its contact page adds Soi Sang Ngoen and the Khlong Tan Nuea subdistrict. Her own website directs private consultations to the clinic. Appointments for consultation and surgery are listed for Thursday evenings, 16:00–20:00, and Saturdays, 09:00–20:00. For anyone flying in, those two days shape the whole trip: plan to be in Bangkok for at least one of them, and leave it to our patient team to confirm the hours currently in force. Saonanon Clinic has no profile page of its own on this site yet, and our research file records no accreditation for it.

King Chulalongkorn Memorial Hospital, Pathumwan. This is the Faculty of Medicine's teaching hospital. You will find it at number 1873 on Rama 4 Road, Pathumwan; it is part of the Thai Red Cross Society. HA Thailand's database shows it holding Advanced Hospital Accreditation through May 2029. It has no entry in the JCI accreditation directory. None of the official hospital pages we read mention an international patient desk, interpreters or airport transfers, so plan as though you will arrange those yourself. Her unit holds its oculoplastic clinic in the Sor Thor (สธ.) building, on floor 8. More about the hospital is on our King Chulalongkorn Memorial Hospital profile.

Language. No official source says which languages Dr. Saonanon speaks. According to the clinic's FAQ, you can contact the clinic in English through LINE. If you want an interpreter present, put that in your request so our team can ask the clinic about it.

Time in Bangkok. In general, eyelid surgery patients allow about 5–7 days in Thailand, roughly the point at which stitches are removed. Swelling and bruising are at their most visible during the first 2–3 days, when cold compresses and sleeping with the head raised help; most bruising has faded by 1–2 weeks. Pack sunglasses, skip swimming pools and eye make-up until she says otherwise, and ask her about eye drops for the flight. Severe pain or any loss of vision after eyelid surgery needs urgent medical attention. As she decides when you are fit to travel, choose a ticket you can change, and with only two clinic days a week, leave a margin around them. Our Bangkok guide covers the rest of the trip.

Small details decide eyelid plans, so good photos and a brief history make the first reply more useful.

Photos (in even daylight, glasses off, with no make-up, false lashes, eyelid tape or glue):

• Straight on, eyes open, looking into a camera held level with your eyes.
• Straight on, eyes lightly closed.
• Eyes looking up, then down, without moving your head.
• A close-up of each eye separately.
• Both profiles, plus a three-quarter view from each side.
• If your lids have drooped over time: older photos showing how they used to look.
• For a revision: pictures taken before your first eyelid operation, if you still have them.

Information:

• Which procedure you are asking about and, in your own words, what bothers you most.
• Earlier eye or eyelid surgery, including double eyelid operations and laser vision correction, with dates, plus any operation notes you kept.
• Eye conditions like glaucoma or dry eye, and your current glasses or contact lens prescription.
• If you have thyroid eye disease: the diagnosis, your treatment so far and recent letters from the doctor treating it.
• Your general health, medicines (blood thinners especially), allergies and smoking.
• The dates you could travel and how long you can stay.

You can mention in your consultation request that photos are ready, and our patient team will explain how to send them.
