"Among potential intraoperative LASIK complications,
perhaps the most feared problems are those related to
the creation of the LASIK flap".

Surgical mishaps during the cutting of the flap may result in serious damage to the cornea. Images of some flap complications may be seen here: Link
There are several types of flap complications including thin flaps, thick flaps, irregular flaps, partial or incomplete flaps, buttonholed or donut-shaped flaps, free caps (the flap is cut completely off), flap striae (wrinkles), and decentered flaps.
Flap complications are inherent to the surgery and have the potential to produce serious vision loss. The best treatment for flap complications is prevention.
Surface ablations such as PRK which do not require cutting a corneal flap are making a come-back with surgeons who wish to avoid dealing with flap complications.

"In interview after interview, surgeons mentioned serious flap
complications as the main reason they've either stopped performing
LASIK or are seeking less invasive alternatives."
