Shifted or dislodged flaps are rare complications, occurring in less than 2 out of 100 patients. This is simply when the flap is significantly moved from its original position. Usually, these complications occur with removal of the eyelid speculum, eye rubbing or other eye injuries. Therefore, it is very important to follow your healthcare provider's post-surgical instructions.

The treatment options and results will vary slightly, depending on the exact problem. However, they need prompt surgical intervention to be repositioned and prevent significant problems.

Wrinkled flaps, on the other hand, are typically a non-emergency and are usually seen on the first postoperative day. They may be left alone if they do not impact the vision, or if needed they may be smoothed into position in the operating suite.
