In your case, you usually need two eyes to do it together, because the doctor is doing a comprehensive eye plastic surgery. First of all, design the radian and shape suitable for you according to your face and eye basic conditions, then remove excess fat and loose skin, and finally make eyelashes upturned by stitching. If you only have one eye, then this eye will be asymmetrical with the other eye, because it has redesigned the radian and shape, removed excess fat and loose skin, and the eyelashes are upturned, making the eye the most symmetrical. But if you insist on making one eye, and that double eyelid looks good, you can make the other one according to the shape of this double eyelid, but there will always be subtle differences between artificial and natural. In addition, when you decide to make eyes, you must be fully prepared and wait patiently for this artificial double eyelid to reduce swelling. It will take a while for the eyes to be symmetrical.
