This is a question I answered for someone who was interested in a double eyelid surgery for Asian eyes:
The double eyelid procedure will help to make your eyes look bigger. Based on the picture, it doesn’t look like you have any crease. Sometimes skin is allowed to override your eyelid margin which can make the eye opening look smaller. Also by creating an eyelid crease, the shadowing contributes to the appearance that your eyes are bigger by creating the shadow the meets up with the dark part of your eyes. Another procedure that can help open up your eyes is the medial epicanthoplasty that is done in the middle part of the eyes that will open the eyes up horizontally. Lastly, you can do a procedure that tightens up the muscle that opens up your eyes but this is advanced, is not standardized or universally accepted to open up your eyes. Here is video on Asian Blepharoplasty and Medial epicanthoplasty.
I hope that was interesting for you!
