The choice between incisional and non-incisional is decided by skin thickness and the amount of excess fat, not by preference. Thin lids with little fat suit the buried-suture method, which takes about 30 minutes and settles within two weeks. Thicker lids, drooping skin or a previous failed procedure usually require the incisional method, which takes about an hour and shows visible swelling for three to four weeks.
The length of your trip is set by the mandatory follow-up interval, not by how quickly you feel well, and flying too early raises the risk of swelling, bleeding and thrombosis.
