What are my options to correct the slope of my lower eyelid? (Photo)

You need an in person consultation to determine the cause of your lower lid retraction/lateral canthal malposition. Depending on the cause will determine the treatment. Typically, these are corrected surgically with a canthoplasty and potential lower lid spacing graft. Best to see an eyelid specialist in your area.

A temporal brow lift can include an orbicularis oculi muscle suspension that can correct a negative canthal tilt.

Thank you for your question. The photos provided are limited and focus on a very small portion of your face, which makes it difficult to offer a precise evaluation. A full set of images—including frontal and side views of the entire face—would allow for a more complete assessment of both function and aesthetics.
That said, the procedure most often associated with correcting a negative canthal tilt (as you described) is canthopexy. This technique adjusts the position of the lateral canthus to achieve a more neutral or slightly upward angle.
As per RealSelf community guidelines, we are not able to provide price estimates within medical responses. However, you can share your full-face photos directly with a clinic’s patient coordinator or surgical consultant, who can help guide you through the process and provide information about cost based on your individual needs.
