Canthoplasty (commonly known as cat-eye surgery) is cosmetic eyelid surgery. It involves reshaping the eyelids to assume a cat’s eye shape, which is often considered attractive and youthful.
The surgery targets the lateral canthus, the outer corner of the eye, where the upper and lower eyelids connect to form a V-shape.
After canthoplasty, the canthus appears raised, and the eyes become brighter, just like a cat’s eyes.
Sometimes, eye doctors refer to canthoplasty as cat-eye lift surgery.
Aside from enhancing looks, canthoplasty can also treat ectropion. Ectropion means the lower eyelids are turned outwards. This increases the chances of eye infections and other vision complications, especially due to overexposure to dry air, dust, and environmental debris.1
Severe ectropion may require canthoplasty to restore the integrity of the eyelids.
Cat-eye surgery must be performed by a highly skilled oculoplastic surgeon.
Your initial consultation and examination will determine whether this eyelid surgery suits you.
The ideal candidate for canthoplasty has:
Canthoplasty is an elective procedure, so insurance will likely not cover it unless it’s required to treat a medical problem, such as chronic dry eyes.
The American Society of Plastic Surgeons (ASPS) estimates the cost of canthoplasty at about $4,120.2 Cost may vary based on your location, available facilities, and the surgeon’s experience.
Talk to your doctor and insurance provider about pricing before committing to the surgery. Some doctors offer financing options such as payment plans.
Cat-eye surgery is an outpatient procedure, meaning you’ll be discharged immediately after surgery. It uses local anesthesia and intravenous sedation to ease pain and help you relax throughout the procedure.3
If your doctor needs to do something more invasive, they will use general anesthesia to make you fall asleep.
The entire procedure lasts about 2 hours or less.
Preparation is important before any reconstructive surgery. You will be required to do the following before canthoplasty:
After administering the local anesthesia, the surgeon will make an incision on the lateral canthal tendon.4 The lateral canthal tendon attaches the eyelids to eye muscles supporting the structure and function of the eyelid.
The surgeon will then detach the tendon and reposition, shorten, or tighten it to achieve the cat-eye shape. An experienced surgeon can hide the scar by making an incision in the eye’s natural crease.
If the eyelids are just slightly sagging, a minimally invasive approach known as canthopexy may be the best option. This procedure eliminates tendon detachment.5 Instead, the surgeon will tighten the eyelids using thread-like stitches known as sutures.
After surgery, the ophthalmologist will close the incision and dress it to prevent infection.
They will prescribe antibiotic eye drops or ointments, steroid eye drops, and/or artificial tears to relieve any pain and discomfort.
They may also provide an eyeshield to protect eyes from dust, debris, and potential trauma, especially during sleep.
Follow these post-op care instructions for successful recovery:
For most people, recovery takes 2 to 3 weeks. Full recovery may take several more weeks.
The recovery process happens in three stages: bruising, swelling, and scar formation. The scars will disappear with time.
The full effects of the surgery (cat-eye-shaped eyes) will become apparent after a few months.
Side effects of canthoplasty include:
In most cases, bruising and swelling will disappear within a week. Vision changes are likely in some people. These symptoms are only temporary.
Potential risks of cat-eye surgery include:
Seek emergency medical care if you experience severe pain, shortness of breath, chest pains, bleeding, or infection after surgery.
According to studies, the average success rate of canthoplasty is over 90%.9
Canthoplasty can be safe, reliable, and successful if done correctly. Trained and knowledgeable ophthalmologists should perform the surgery and only on suitable candidates.
Depending on the person’s condition, other surgeries, such as double eyelidplasty or epicanthoplasty may be necessary to provide the best results.8
Canthoplasty is an inpatient surgical procedure that improves the eye’s appearance. It involves cutting, repositioning, shortening, or removing excess skin from the outer part of the eyelids.
Once done, the eyes assume a cat’s eye shape, which is a commonly desired cosmetic feature.
Canthoplasty also corrects drooping eyelids and ectropion, a condition characterized by outwardly turned lower eyelids.
For best results, only an experienced eye surgeon should perform this procedure.
