LASEK is safer because there is no flap created in the cornea, so all flap-related complications are eliminated!
Because there is no flap, LASEK preserves more corneal tissue and allows higher amounts of correction to be performed during laser treatment on the eye—as high as -14.00 D in certain cases! For this reason, LASEK is also preferred in patients with thin or irregular corneas.
LASEK is more comfortable than PRK because the skin is put back into place rather than discarded, allowing for more rapid visual recovery without significant discomfort.
LASEK is a better choice for people who are concerned about procedures that require cutting the eye.
