What are the risks of upper eyelid surgery?

Dear Alexa
Please don't let anyone rush you into eyelid surgery because it is simple and straight forward. My colleagues have done a good job describing the textbook issues that can arise after upper eyelid surgery.
However, by far the most common and most important potential complication is a failure of communication between you and your surgeon. You go to the doctor and you might even ask for an upper eyelid blepharoplasty. However this may or may not be what you need. The doctor might even agree to preform eyelid surgery, after all the surgeon may consider this a very simple procedure.
Here is the issue: is this what you need? Most people assume that they need eyelid surgery when the upper eyelid fold hangs onto the eyelid platform or eyelashes. Due to how the brain is wired, the upper eyelid fold is supported by activity in the forehead lifting muscles that raise the eyebrow. When upper blepharoplasty is performed, the skin resting on the eyelid is removed and so is the signal for the forehead muscle to activate. The forehead relaxes and the eyebrows fall. This can make the eyes look smaller after upper eyelid surgery. In this circumstance, the correct surgery is not upper eyelid surgery but rather an endoscopic forehead lift.
Another area for disappointment is loss of the upper eyelid fold itself. Many surgeons will resect all the available upper eyelid fold while still permitting the eyes to close. This is generally a big surprise to the patient. The upper eyelid fold is a very important aesthetic feature of the face. The unexpected loss of this important feature can lead to long term disappointment with the surgery. The surgeon often does not understand why the patient is unhappy with surgery because to their thinking, this is what eyelid surgery is supposed to accomplish. However, the answer here is that most people would preserve the fold but have it cleaned up if they had been given the choice. It is possible to do very elegant eyelid surgery and yet leave the upper eyelid fold.
Other areas of disappointment include the placement of the upper eyelid crease too high. The plastic surgery textbooks routine describe making the lowest upper eyelid incision 10 mm above the eye lashes. However, this is much too high. Normally in women, the natural upper eyelid crease is actually located at about 8 mm. However, when an incision is made, the final location of the incision will be 1 to 2 mm higher than intended due to how the eyelid heals. So the 10 mm incision heals to a 12 mm height. This is a very bad thing. It is much safer to place the incision at 6 or 7 mm.
Also, it is important to put the eyelid platform skin on slight stretch. This tension helps support the upper eyelid lashes so they perk up after surgery rather than point down. This maneuver is called anchor blepharoplasty. To perform it, the eyelid platform skin needs to be attached to the tendon that raises the upper eyelid. This requires a specialized knowledge of eyelid anatomy that most eyelid surgeons lack.
So the biggest risks of the surgery come from a lack of a detailed and systematic approach to performing eyelid surgery, through consultation and communication. If you spend less than 5 minutes with your potential eyelid surgeon, this should be a big red flag.

The risk of eyelid surgery is similar to risk of any surgery, minor or major, every surgery always has the risk of bleeding, infection, injury to surrounding tissue or the need for revision. But eyelid surgery when properly done in experienced hands is usually a procedure that requires minimal risk and need for revision. During surgery if the incision is near the eyeball, often a protective shield will be used. So in general very safe surgery.

Bleeding and infection are early problems.  Dryness of the eye is common but only lasts a few days or weeks.  Upper lid bleoharoplasty is a very easy procedure to go through and heal from.

Upper blepharoplasty is a fairly straightforward, minimal risk surgery in experienced hands. The scarring is in most cases hardly perceptible, and and wound healing problems/infection are extremely rare due to the generous blood supply in the area. The anatomy is fairly consistent, limiting the chance for damage to surrounding structures, again in the hands of an experienced surgeon. Perhaps the greatest risk is that of under or over resection of skin. Again, accurate judgement on the part of the surgeon comes with experience. Over-resection can result in dry eyes, but his is usually self limited as the upper eyes are very forgiving. Under-resection is easily corrected by excising additional skin. Please not that many cases of post-operative lid heaviness are really due to brow droop rather than upper lid skin excess. Surgeons often point out that patients should have a brow lift before or in conjunction with upper eyelid surgery. This may come as a surprise to patients as the public is more familiar with upper eyelid skin excision as opposed to brow malposition. For best results, discuss this with your surgeon prior to surgery.

Upper lid surgery is not a very risky surgery if performed by a well trained physician. The surgery involves removing excess upper lid skin and herniated fat. Care must be taken not to remove too much skin, or the eye won't close and the eyes can dry out. Other risks include scarring and asymmetry (one side different from the other). Infection is rare. Bruising is usually minimal and resolves in about a week.

As with any major cosmetic surgery, there are inherent risks associated with upper eyelid surgery. Some of these risks include intense and unsightly swelling, bruising, bleeding and scarring. Along with the specific risks associated with an upper eyelid blepharoplasty, there are general risks such as infection or any adverse effects to medication or anesthetics. While some patients think they want upper eyelid surgery, the desired results can sometimes be achieved with similar procedures such as an eyebrow lift or other non-surgical alternatives. I have repeatedly seen patients walk into my office and stubbornly insist on having a procedure done when in reality it might not improve their situation as much as an alternative surgery or non-surgical option. Please be sure to fully explore all options and risks before undergoing any major surgery, especially one on such a sensitive part of your face.

Thank you for your question. Complication are uncommon and when they happen they are usually mild and transitional, such as hematomas and chemosis, infection and bleeding, dry, irritated eyes etc. Nonetheless, sometimes they can be definitive such as blindness, or they require new surgical approaches for correction, such as ectropion and eyelid ptosis. These complication prevention or even their forecast starts with careful preoperative assessment (include detail clinical history and careful physical examination). Also the surgical technique to be used is based on the anatomical changes found and the patient's complaints, always taking into account patient expectation and the real surgical possibilities for cosmetic improvement. These will suggest why it is best to be treated by an expert whether a plastic surgeon, oculoplastic, or ENT.All The Best

The risks of blepharoplasty are minimal but excessive swelling, persistent fat or loose skin, dry eyes, and rarely visual loss have been reported.

Over correction is the most common complication. This could result in poor eyelid closure, an artificial appearance, sunken upper eyelids, elevated lid crease and dry eyes. Asymmetry is another relatively common problem. In addition, if the surgeon does not recognize certain issues before surgery, the results will be poor afterwards. This includes eyebrow ptosis (drooping), eyelid ptosis and lower eyelid abnormalities. You should see an eyelid specialist (oculoplastic surgeon) for evaluation and for a treatment plan tailored to your specific issues. 

                  Complications
following blepharoplasty surgery are fortunately uncommon. This procedure is
associated with high patient satisfaction rates and low complication rates.

                  Complications
seen with blepharoplasty include infection, bleeding, hematoma, asymmetry,
excess scarring, injuries to the eye, blindness and dry eye syndrome.

                  In
addition, rarely patients have less then optimal aesthetic results which requires
secondary surgery.

                  It’s
important to understand that the majority of patients have uneventful
recoveries and are extremely happy with their aesthetic results. 

Fortunately, most complications following an eyelid lift are minor and self-limiting. Prolonged bruising, swelling, and irritation of the conjunctiva are the most common, minor complications following eyelid surgery.

More serious complications following an eyelid lift include removal of too little or too much skin, cysts at the suture line, or eyelid malposition. Most of these complications can be corrected in a small, revisionary procedure performed under local anesthesia in an office setting.
