Now that you've had a Korean double eyelid surgery cut, don't think about restoring the single eyelid. I feel a little uncomfortable when I just cut my double eyelids, but I get used to it after a long time, so please don't entangle, and my left eye will recover. The above is a suggestion on the question "Can a failed double eyelid be repaired into a single eyelid in four months?". I hope it helps you, and I wish you good health.
