Is There a Way to Increase Eye Size for Asians?

Scaring the eyelid to increase the visible white of the eye is a high risk procedure.  Your friend was happy. However, if things don't go well, they could be very unhappy.  Will this be right for you?  I for one would not recommend or endorse this approach.

You can increase eye size for Asians by increasing the space between the lids. The eyeball itself cannot be increased. There is a common surgery that we can do either to create a double eyelid crease which can make the eye appear more rounded and less oval. And we can actually lift the lid where the lid is too low. It’s important to go to someone who really specializes in eyelids to help you decide which surgery you need, but both can be done in a way that looks very natural.

Surgery to cut the corner of the eye, (the "canthus"), is risky, in that this is a supporting structure of the eye. You may want to try a small, (1-2 units) of Botox in the middle of the lower lid just under the lashes which does "open" the eye a bit. find a physician whom does this and you may be happy with the result, and it is safe!
