Based on what you are describing, a lateral canthopexy is often one of the key procedures used to improve the lateral canthal angle and help restore a more natural position to the outer corner of the eye. After upper blepharoplasty, some patients can develop rounding, downward pull, or subtle malposition of the lateral corner, especially if there was underlying lower lid laxity or changes in support around the eye. A lateral canthopexy helps reinforce and reposition the outer corner of the eyelid to create a more natural, youthful contour. The exact approach depends on the degree of malposition and your anatomy. In milder cases, a canthopexy alone may be sufficient; in more significant cases, a formal canthoplasty or additional lower eyelid support procedures may be needed. I would recommend evaluation by a board-certified plastic surgeon who specializes in eyelid and facial rejuvenation surgery, as these are nuanced procedures where precise vector control and eyelid support are extremely important for achieving a natural result.
