Non-incisional vs. incisional double eyelid surgery: what the research shows

What does double eyelid surgery aim to do?

Many East Asian people are born without a double eyelid, so methods for creating an eyelid crease have been studied for decades ^[4]. One review of the incisional method names a long-lasting, natural-looking crease (the supratarsal crease) as the main goal ^[5].

What looks natural differs from person to person. A review of double eyelid surgery in East Asian patients explains that setting aesthetic goals means also considering cultural background and preserving a person's original look ^[1]. The same method will not produce the same result for everyone, so it is important to agree on the specific shape you want before surgery.

The non-incisional method: no skin incision

The non-incisional method (nonincisional blepharoplasty) creates a double eyelid crease with sutures, without cutting the skin. Many variations have been described, and the approach is regarded as simple, minimally invasive, and efficient ^[2]. One group of surgeons reported that they prefer a single continuous stitch of fine nylon suture passed through the full thickness of the eyelid ^[2].

The same review concluded that choosing the right patient and the right technique can produce a natural double eyelid and reduce the chance of the crease coming undone ^[2]. This can also be read as a reminder that no single technique suits every eye.

The partial-incision method: adjusting tissue through small incisions

The partial-incision method (small-incisional blepharoplasty) uses one or more short incisions in the eyelid. A 2023 systematic review analyzed 13 studies and 4177 patients: 5 studies (2460 patients) used one incision, 2 studies (645 patients) used two, 5 studies (700 patients) used three, and 1 study (372 patients) used four ^[3].

Through these small incisions, the surgeon can remove as much of the soft tissue in front of the tarsal plate (tarsus) as needed and secure the crease firmly and precisely ^[3]. Both the one-incision and three-incision approaches had a pooled complication rate of 5% and a crease loss rate of 2%, with no significant difference between the two groups ^[3].

The authors concluded that this method shortens recovery and that its rates of crease loss and complications are acceptable compared with the non-incisional and incisional methods ^[3]. However, the included studies varied widely in the number of incisions, how tissue was removed, and how the crease was secured, so the findings are hard to treat as results for one standard technique ^[3].

The incisional method: balancing stability and movement

The incisional method (incisional blepharoplasty) is considered an ideal way to create a double eyelid crease ^[4]. However, the classic approach tends to give a stable crease at the cost of less natural movement when the eyes open and close, so later refinements have focused on finding a balance between stability and dynamic movement ^[4].

Ways of forming the crease have also evolved, from directly fixing the skin to the tarsal plate to a range of methods aimed at a crease that moves more naturally ^[5]. A review comparing 19 studies sorted the techniques into four biomechanical types based on the main point of fixation, and noted that the differences between techniques were often not clearly explained along with their underlying principles ^[5]. Which approach is better is still being debated ^[4].

A 2026 systematic review summarized the key steps of the incisional method as the three below ^[4].

• Debulking the eyelid: removing skin, the muscle around the eye (orbicularis oculi), the fat behind that muscle, and orbital fat as needed
• Adjusting the eye-opening structures: refining the levator tendon (aponeurosis) and surrounding structures so the eyelid covers the cornea by the right amount
• Connecting the front and back layers: joining the front and back layers of the eyelid to form the double eyelid crease

Recovery, complications, and revision surgery

Whichever method you choose, the recovery process, possible complications, and the chance of needing revision surgery should all be explained to you before surgery. A review that walked through the incisional method step by step also treated preoperative planning and consultation, the course of recovery, and complications and revision as key topics in care before and after surgery ^[1].

The crease coming undone or becoming fainter is a risk to check with any method. The systematic review of partial-incision techniques tracked it as a separate outcome ^[3], and the review of the non-incisional method considered choosing the right patient and technique important for reducing crease loss ^[2].

Recovery time varies with the extent of the incision, the amount of tissue removed, and your individual condition. The authors of the partial-incision review judged that small incisions shorten recovery ^[3], but the actual timeline differs from person to person, so it is best to confirm it with your surgeon.

What to ask during your consultation

Researchers stress that surgical plans tailored to each patient's anatomy will be needed going forward ^[4]. Recent trends in surgery around the eyes have also moved toward preserving tissue volume and avoiding skin incisions or making them less visible ^[6]. Rather than focusing on the name of a method, it is more important to first be examined to find out what your eyelids actually need.

• The condition of your eyelid skin, muscle, and fat, and which method fits it
• The height and shape of the double eyelid you want, and what looks natural to you
• What happens if the crease comes undone, and the possibility of revision surgery
• Expected recovery time and when you can return to daily life
• An explanation of the complications for each surgical method
