i have a very small monolid asian eye. i want to enlarge it, both in height and width. However, i don't want to have a double eyelid. I only want big eye but still monolid and no crease after the surgery. Is this possible? And is it more difficult and more risky to perform? and how much will it cost? also, is there any long term risk? is this is a risky procedure? and do i have to visit the doctor for the rest of my life to get something like routine injection or taking medicine after the recovery? Thank you so much..
