What keeps the corneal flap in position after LASIK surgery?
You will be relieved to know you will not need any stitches. Initially, a vacuum effect keeps the corneal flap in position. The cells lining the inner surface of your cornea, known as endothelial cells, pump water out to the inner part of the eye. This suction holds the corneal flap in place. During the first day or two after surgery, the outer surface of the cornea, known as the epithelium, seals the edges of the corneal flap. Over the next few weeks, natural substances inside your cornea bond the corneal flap to the underlying tissue.
