How dangerous is upper eyelid surgery?

Any surgery in the wrong hands can be potentially dangerous. In the well-trained hands such as a board-certified plastic surgeon, a board-certified ENT surgeon or a board-certified oculoplastic surgeon there will have minimal if any complications.

However, as with any surgery there are risks associated with this surgery.  The real question is surgery right for me.  This assessment weighs you concerns and likely benefits against potential risks.  This comes down to individual considerations.  Generally it is best to find a surgeon with a great deal of experience and appropriate training to manage any concerns that might develop.  Because only board certified ophthalmologist are trained to examine and manage eye comfort, it makes sense to seek out a fellowship trained oculoplastic surgeon.  This is a board certified ophthalmologist who is fellowship trained in oculoplastic surgeon.  Generally, most oculoplastic surgeons seek fellow status with the American Society for Ophthalmic Plastic and Reconstructive Surgery.  They maintain a website with a regional directory to help you find a highly qualified surgeon close to home (ASOPRS dot org).  My website has extensive discussion of safety concerns associated with eyelid surgery and you don't have to be a patient of mine to benefit from the information on this website.

The biggest risk is bleeding which is temporary. Other risks include lagopthalmus (difficulty closing the eyelids which can result in dry eyes), ptosis (hanging eyelid), infection, scarring, asymmetry. Typically the risks are very small and if a conservative amount of skin is removed, the risk is extremely small and very safe and can often be done under local anesthesia. Good luck in your area.
