WHAT HOLDS THE FLAP IN PLACE AFTER LASIK AND DOES THE FLAP EVER COME LOOSE?
The LASIK flap is remarkably secure. Unless an eye had experienced significant trauma, I am not aware of a flap becoming dislodged after LASIK. The flap is primarily held in position by it’s inherent shape, like a piece of a puzzle. The flap is also held in place by the normal physiologic activity of the cornea, by mucopolysaccarides (a gluey substance secreted by the corneal cells), and by the overlying corneal epithelial cells (the clear, skin-like layer that covers the cornea).
