What is the risk of lateral canthopexy and the cost of it? Can it be done under local anesthesia?

Lateral canthopexy can be done under local anesthesia but usually it is not a useful technique. Even canthoplasty may not be adequate as more extensive lower eyelid surgery may be necessary, depending on the exact eyelid problem and desired outcome. Consultation with photos if necessary.

The greatest risk of a lateral canthoplasty is that it is the wrong single surgery to correct your lower eyelid issues.  You have not provided a photograph but when you have had lower eyelid surgery and have an issue, lateral canthoplasty alone is seldom the right answer.  Tightening the lower eyelid does not have the proper mechanics to fix what is wrong with these eyelids.  For this reason, it is often necessary to address a number of factors that occur simultaneously in these damaged eyelids.  In fact, lateral canthoplasty alone can actually pull the lower eyelid down further below the curvature of the eye worsening the overall situation.

Thanks for the great question a lateral canthopexy is not typically performed all by itself. It is however commonly used as an adjunct to lower lid surgery. A canthopexy is the first in a range of procedures to help tighten and support the lower eyelid. It is something that can be performed under local if need be. I recommend seeing a surgeon in your are for more information on the procedure and pricing. Best,~Dr. Sieber
