Is it possible to change tapered eyelid to parallel eyelid?

A tapered crease can be altered towards a parallel crease. Often this will also include an epicanthoplasy which open the eyes horizontally. An in person consultation with an oculoplaslastic surgeon can help you decide if it's a right choice for you.

Yes, typically you can.  It would usually require incision technique with anchoring sutures and there's a possibility the a medial epicanthoplasty would be needed (although I prefer not to perform epicanthoplasties when possible).  You skin elasticity and the depth of your eyes can sometimes effect how noticeable a parallel crease can be made.Consult only with surgeons who clearly perform Asian eyelid surgery regularly.Chase Lay MDAsian eyelid surgery specialist.
