Can I change my double-eyelid eyes to a monolids eye?

It would be difficult to determine this without seeing you for a
consultation.  Without seeing what areas
you are talking about, it is hard to know what technique would be best to treat
the area.  You should discuss your
concerns with your Plastic Surgeon.

Thank you for sharing your question. Most Asians prefer to create a well-defined crease. It is possible to remove the crease, but you will probably be disappointed with the results. See an experienced Oculoplastic Surgeon who has computer imaging which could give you an idea of how you are going to look after surgery. Good luck,

A personal consultation is really needed to determine if your goals are realistic.  Consider also posting photographs of yourself.

Hello!
Despite my work and expertise, i'm with you, I love the look of Monolids especially when it fits the features of someones face.  Despite what non-Asian (White people may think) Asians don't always "prefer" a visible crease or noticeable crease.  In any case if you gave use a photo that would help.  There are some situations in which you can raise a lid crease through a ptosis-style surgery or by adding volume to the upper lid but the options are limited.It's also VERY IMPORTANT TO UNDERSTAND that procedures that describe simply moving the crease down or relocating a crease in a lower position with a simple change in incision placement is grossly inaccurate.  Be careful.
Could you post a photo?
