It's not a good idea to fly home 2 - 3 hours after eyelid surgery for a few reasons. First, it is important to rest after eyelid surgery. Any activity (including walking) increases blood flow to your eyes and raises the risk of bruising and swelling. Carrying a suitcase raises the risk even further. You should be resting with your head elevated and with cold compresses on your eyes for the first 24 hours.
In addition, with any eyelid surgery, there is a very small chance of bleeding behind the eyes that could cause vision loss. This is reversible if addressed right away. If that were to happen on an airplane, there is little chance that there would be a doctor on your flight who would know what to do.
When you have surgery on your eyelids, ointment is placed in your eyes immediately afterwards to protect your eyes from getting too dry. This ointment will blur your vision and make it difficult to see clearly. This would make traveling more complicated.
And finally, surgery schedules are not adhered to precisely. You could easily have surgery an hour later than you expect. You may need to stay in the recovery room longer than expected. If you are delayed, you could miss your flight or need to rush to make it. This kind of stress will increase your chance of complications.
It's a good thing that you are thinking about this beforehand and doing your homework. I think of surgery as a "team sport." Your doctor is the quarterback, and you must be a good receiver. Good luck with your surgery.
