Asymmetry is normal, and may be improved on with surgery; however, if your goal is to create complete symmetry or you want to do surgery only because of the asymmetry then you may not be the right candidate for surgery. Please post your photos so that we can give you better recommendations.
Hi. It sounds like you are describing ptosis, but it's impossible to tell without photos. If you actually have ptosis, it can be corrected surgically. Best regards, Ira Vidor, M.D.
Thank you for sharing your concerns. Asymmetry is not uncommon. It always appears worse to the individual than others looking at the person. Most of the time, the problem is correctable. Often ptosis (drooping) or dermatochalasis (extra skin) is the problem. See an experienced Oculoplastic Surgeon for comprehensive evaluation and discussion of treatment plan tailored to your needs.
There are many options to address eyelid asymmetry depending on the cause. Photos are necessary to give you advice.
