Eyelid Correction Revision: Causes and Fixes for Overcorrection and Undercorrection
Eyelid correction that leaves eyes too wide open or still heavy can be fixed with revision surgery. Here is how overcorrection and undercorrection are treated.
“
My eyes look too round and wide open after eyelid correction, and they don’t close well.
On the other hand, even after surgery, my eyes still feel heavy.
Eyelid correction is not surgery to make your eyes bigger. It adjusts the function of the muscles that open your eyes. If your eyes open too widely after surgery or still feel heavy, revision surgery may be considered to return the muscles to a normal range.
When to Consider Revision Surgery
Your eyes should open naturally and comfortably right after surgery. However, in the early stages, swelling can make the two eyes look uneven, so we monitor your progress together. Revision surgery to return the eyes to a normal range may be considered in the following cases.
• Overcorrection
The muscle becomes too short, so the eyes look startled and wide open (tōan), or they cannot close completely. This condition, in which the eyelid rises excessively and exposes the whites of the eyes, is also called eyelid retraction.
• Undercorrection
This occurs when the muscle is left too long, or is tied down too tightly and cannot move through its full range. The pupils are covered, making the eyes look sleepy, and the double eyelid crease does not fold properly.
• When the double eyelid crease interferes with the muscle
This happens when the double eyelid crease is set too high or fixed too tightly, blocking the movement of the muscles that open the eyes.

Eyes that have normal eye-opening strength but look droopy only because of loose skin are called ‘pseudoptosis.’ If eyes like this are treated with eyelid correction, they may open too widely or fail to close fully, so they must be distinguished before surgery.
Overcorrection and undercorrection can sometimes occur in the same person. In a U.S. study of 1,519 patients (average age 63, most with age-related eyelid drooping), 8.7% underwent repeat surgery after eyelid correction, and undercorrection was the most common reason.
There Are Two Muscles That Open the Eyes
The eyes are opened by two muscles, the levator palpebrae superioris and Müller’s muscle, which differ in both location and the nerves that control them.
• Levator muscle
This muscle moves when you consciously decide to open your eyes, as in “Time to open my eyes.”
• Müller’s muscle
This muscle moves on its own when you are tense, such as when you are startled. It is very delicate and easily damaged, and scarring can occur. A Japanese study also found more recurrences with methods that fold and tie only Müller’s muscle, as the muscle became thinner or changed.
This is an illustrative diagram showing the positions of the two muscles.
How Are Overcorrection and Undercorrection Fixed?
Overcorrection — Re-lengthening the Shortened Muscle
When correcting eyelid retraction that occurs after surgery, the end of the muscle is carefully separated. Next, the thin membrane at the end of the muscle (the aponeurosis) is moved back by the appropriate distance and reattached to the tarsal plate. If there is not enough aponeurosis, tissue is grafted into the gap to connect them.
Undercorrection — Shortening the Muscle Again
After assessing how much the eyelid droops (the distance from the tarsal plate), the muscle is shortened again. If the double eyelid crease is judged to be interfering with the muscle, the double eyelid is also recreated during the revision eyelid correction.

Gangnam Dr. Woo’s Principles for Eyelid Correction Revision ① Tissue preservation — The aponeurosis is essential tissue, so we leave some spare tissue. The more tissue that remains, the higher the chance that revision surgery will improve the result. |
For revision surgery, we usually recommend waiting until six months after the tissue has stabilized. However, if daily life is difficult, such as when the eyes do not close well, a decision can be made earlier after an examination by the clinic director.
Side Effects and Post-Surgery Care
The following reactions or side effects may occur after eyelid correction revision surgery:
- · Swelling and bruising — Most people experience these, and they subside over time. While the swelling goes down, the two eyes may look uneven in height.
- · Bleeding, hematoma, and inflammation — These may occur.
- · Incomplete eye closure, dry and gritty eyes, and damage to the corneal surface — These may occur.
- · Uneven eye height, and a hollowed or uneven eyelid contour — These may occur.
- · The other eye looking droopy after only one side has been operated on — These may occur.
- · Re-drooping or excessive eye opening — These may occur, and in such cases another surgery may be needed.
In the early days after surgery, applying cold compresses and sleeping with your head slightly elevated can help reduce swelling. Avoid alcohol, smoking, saunas, and strenuous exercise for a while. Do not rub or press your eyes. Follow your attending doctor’s instructions for washing your face, applying makeup, and wearing contact lenses.
The recovery period and speed of recovery vary from person to person after revision surgery. It is more important to focus on your own progress than to compare yourself with others.
If You Have Questions If your vision suddenly blurs after surgery, or if pain, bleeding, or swelling becomes severe, please contact us right away. If you tend to raise your forehead to open your eyes or your eyes tire easily, please let us know during your consultation. Whether your previous eyelid correction was an incision or non-incision procedure also helps with diagnosis. Phone consultation: 055-338-7585. |
In Closing
The goal of eyelid correction revision surgery is to restore the ability to open and close the eyes to a normal range, rather than focusing on eye size. The approach differs depending on whether the problem is overcorrection or undercorrection, and whether the double eyelid crease is interfering with the muscle, so an accurate diagnosis of your current eye condition comes first. The cost and recovery period for eyelid correction revision surgery vary depending on your condition, and we will explain them during a consultation after your examination.
Frequently Asked Questions
Q. Does everyone who raises their forehead to open their eyes have ptosis?
No. Ptosis is a condition in which the eyelid covers the pupil because the strength to open the eye is weak. When there is no double eyelid crease and the skin covers the pupil, people use their forehead muscles to lift the drooping skin. This kind of ‘pseudoptosis’ is different from weak eye-opening strength, so a clear eye shape can be expected with double eyelid surgery. After surgery, as the strain on the forehead is released, the eyebrows may drop slightly.
Q. Does non-incision eyelid correction always lead to recurrence?
No, that is not the case. Making an incision to directly see and adjust the muscle is the preferred approach, but if a specialist’s diagnosis determines that this method suits the eye, some patients may see results. A Japanese study also found that most mild ptosis was corrected, but the rate of complete correction was low for moderate cases. However, studies on recurrence have short follow-up periods, so it is hard to say definitively how long the results last.
Q. What methods are used for a first-time eyelid correction?
It depends on the degree of drooping. For mild cases, only the aponeurosis is tightened. For moderate cases, both muscles are tightened together, leaving a margin of spare tissue. For severe cases, the excess loose tissue is trimmed away. If the muscle has almost no strength, the eyelid is lifted by attaching it to a different membrane called the common fascial sheath (CFS). Our clinic believes that severe ptosis should be treated using the common fascial sheath to lower the risk of recurrence.
