Canthoplasty or cat eye surgery is one of the types of eye cosmetic surgery that has gained many fans in recent years. This operation is usually associated with lower eyelid surgery and makes your eyes bigger and longer. In addition, by using this procedure, you can make your eyes more beautiful and give your face a more attractive look.

Although the cat eye operation has been popular for several years and reputable clinics perform it, there are still many concerns about it. These concerns are mostly related to the complications of this procedure and the possibility of causing damage to people's eyes and vision. In this article, we intend to clarify these points and solve your concerns by fully examining this procedure and the way it is performed.

What is canthoplasty or cat eye operation?

Canthoplasty, which is also known as cat eye surgery, is usually done to change the shape of the eye and make it more elongated. The main purpose of this procedure is to enlarge the eyes. By using this surgery, you can make your face more attractive and younger. In canthoplasty, surgery is usually performed on the lower eyelid, and in this way, the inner corners of the eye are reconstructed.

5 signs that make you a candidate for canthoplasty or cat eye surgery

Our recommendation is that before any action to perform the cat eye surgery, you should definitely participate in the consultation sessions with the doctor. In these sessions, the doctor will make your expectations more realistic by showing photos or videos of the cat eye operation and show you the results of the operation.

Anyone with general health can use this operation to make their eyes more beautiful and elongated, but in general, if you have these characteristics, you are a more suitable candidate for eye canthoplasty:

  1. You have short horizontal eyes
  2. You have very close eyes
  3. You had unsuccessful blepharoplasty or eyelid surgery
  4. You want more elongated eyes
  5. You have sad and tired eyes

What are the different methods of cat eye surgery?

There are different techniques for lifting by cat eye surgery. Therefore, by participating in the pre-operative consultation sessions, help the doctor choose the best method to make your eyes more beautiful.


Canthoplasty surgery is usually performed using local anesthesia and takes about 2 to 4 hours. Of course, in some cases, the doctor may also use general anesthesia. In this method, first, a small incision is made in the circular muscle of the eye. After that, the external canthal tendon, which is located on the side of the eye socket, is slightly separated from the bone and cut.

In the continuation of this operation, the internal structure of the lower eyelid should be brought to the place of the tendon cut. For this purpose, this structure is slightly pulled up to reach the bone of the eye socket. After connecting these two parts, the excess skin is cut and the created incision is sutured.

Ectropion or lowering of the lower eyelid

As age increases and skin collagen decreases, the skin gradually becomes loose and sagging. This relaxation will be seen earlier in the areas around the eyes where the skin is thinner and more sensitive. If the drooping of the lower eyelid is not too severe yet, you can use other methods of eye lift or cat eye surgery to fix the drooping and pull the eyes. But if the drooping eyes are such that the lower eyelid is turned outward, the ectropion method is the most suitable method for you.


Some centers may use the name canthopexy instead of canthoplasty, but these two methods are different. In the operation of canthopexy, no incision is made in the circular muscle. In this method, no part of the tendon is cut. To pull the eyes in canthopexy, the circular muscle and the external canthal tendon are brought together and collected using a suture.

In this way, a little extra skin is created in the lower eyelid. In the continuation of the procedure, these skins will also be removed so that your eyelid does not look loose and droopy. This method can also be used to fix the drooping of the lower eyelid.

Epicanthoplasty or pulling the inner corner of the eye

You can combine this method with external canthoplasty to achieve a more attractive appearance and more elongated eyes. But if you like to draw only the inner corner of your eye, using epicanthoplasty is enough for you. Note that both methods require a lot of precision and skill. Therefore, if you plan to use a combination of two methods, be sure to make sure of your doctor's expertise.

Lateral canthoplasty or pulling the outer corner of the eye

This surgery is usually used to remove drooping of the upper eyelid and pull the eyes. Of course, in some cases, the lateral canthoplasty method can also be used to eliminate drooping of the lower eyelids. If you take a look at the photos of Korean models, you can clearly see the results of this procedure.

Korean models use this method to fix their drooping upper eyelids and make their eyes bigger. In addition to lifting the eyelids and smoothing the area around the eyes, in this method the outer corners of the eyes are also pulled up so that your eyes have a cat shape.

Canthoplasty cost

It depends on which method you use for canthoplasty. The cost of the operation can also be different. Also, if you want to use the combined operation and combination of cat eye operation and eye and eyebrow lift, your cost will be higher.

Canthoplasty complications

If you are confident enough about the skill and expertise of your doctor, leave this surgery in his hands and follow the doctor's instructions correctly. The cat eye cosmetic procedure will not be associated with dangerous complications for you, and you will have a short recovery period of 2 to 4 weeks.

During the recovery period, it is completely normal to feel some pain around your eyes and it is accompanied by side effects such as swelling and bruising. To reduce the swelling, you should rest well and avoid putting pressure on the eyes. These side effects will disappear after about a week.

Another side effect that worries you after the surgery is the stitches and scars. The stitches created in this procedure are in the lines under the eyelids or inside the eyes, so you will not see any stitches or scars. Even after complete recovery, no one will notice the location of your surgery, and if the wounds take a long time to heal, it is better to contact your doctor.

You should pay attention to the fact that cat eye cosmetic surgery must be done professionally and is a very sensitive procedure, so before any procedure, make sure of the credibility of the clinic and the skill of your doctor so that you do not experience rare and dangerous side effects.

The most important difference between canthoplasty and blepharoplasty

Many people think that canthoplasty is another name for blepharoplasty. While canthoplasty and blepharoplasty are two very different surgeries and you should not confuse them with each other.

In blepharoplasty surgery, eyelid drooping is treated by removing excess skin and fat without significantly changing the eye position. On the other hand, the reason for performing canthoplasty surgery is to change the shape of the eyes.

By performing canthoplasty, the corner of the eye will be raised and the eyes will take on an almond-shaped and elongated shape. Many people perform these two surgeries at the same time in order to remove the bags under the eyes and have bigger and more elongated eyes. Since the side effects of canthoplasty are less than blepharoplasty and the recovery period will be shorter.

Despite the differences, these two surgeries also have similarities. For example, the steps to prepare for surgery and after care are almost the same in both surgeries.

Last words

Today, there are various methods for cosmetic eye surgery, one of which is cat eye surgery. Because this surgical method is very easy and has few complications, it has become more popular than other methods. So, if you intend to have a livelier and younger face by drawing your eyes, you need to consult a plastic surgeon about this.

Frequently Asked Questions

  • No, if you have done cat eye surgery in a reputable clinic, you will not see any of these side effects. Because the surgeon is well skilled in doing this work and does not damage the tissues or nerves of the eye. Of course, in some cases, you may have a little trouble seeing immediately after the surgery. This problem is usually completely resolved a few days after the surgery and your vision returns to normal.

  • If the surgical incision is made from inside the eye, the doctor will use absorbable sutures. Otherwise, the incision is made under the eyelid and the sutures will be non-absorbable. If non-absorbable sutures were used, the sutures are usually removed three to five days after the operation.

  • You cannot wear eye make-up immediately after surgery. Avoid doing this at least until the stitches are removed. After that, it is better to hold back for a day or two. Usually, patients can use eye cosmetics a week after surgery. Of course, it is better to consult your doctor before using any cosmetics.
