It depends on whether skin needs to be removed and other factors. In either case, the incision is very well hidden and again, fat is removed as needed. Usually, the upper lid is operated on first, then the lower lid. Depending on the extent of the surgery, the procedure may last from one to two hours. After the operation some soreness and discomfort may remain.
Actual pain is rare.
If pain is experienced, it should be mild and can easily be controlled with medication. One should rest quietly with head slightly elevated. Cold compresses may be applied to eyes to reduce post-operative swelling and bruising. Eyelids will be swollen and sore for about 5 days. Eyes will be sensitive to light, wind and dust for 2 to 4 weeks.
