Lower Eyelid Surgery Risks

Canthoplasty and canthopexy are relatively minor procedures and do not have many serious risks, but they do have some risk. As with all surgery, there is the possibility of complications due to anesthesia, as well as the risk of infection or nerve damage to the eyelids. The eyelids may also end up being asymmetrical.

Canthoplasty Risks

The more invasive canthoplasty procedure carries more chance of problems than does canthopexy. Because the orbicularis oculi muscle around the eye is cut, scar tissue forms that can interfere with the function of the muscle. The lateral canthal tendon at the corner of the eye is cut and shortened, and the lid is pulled in and reattached to the bone where the tendon was. If further problems with the lid develop in the future, there may not be enough tissue left in the lid to correct it any further. Future corrections may result in an undesirable change in the shape of the eyes.

Other Risks

Minor complications for both canthoplasty and canthopexy include temporary blurred or double vision, temporary swelling, and excessive scarring. Rare complications may include ectropion, where the lower lid is pulled down or gapes open, or entropion, where the lid is pulled too tightly and curl inwards. Further surgery may be required to correct either condition.
