A wet sponge is used to gently squeeze out excess fluid in the flap edges, further speeding the re-adhering process. Finally, Dr. Horn takes a dry sponge or spatula, a thin rod like instrument, and repeats the maneuver, further drying and thinning the previously soaked edges of the flap. Once another two minutes of drying take place Dr. Horn rechecks the firmness of the flap adherence which by this time is typically quite strong. Drops are then applied, reestablishing the luster of the cornea, and leaving the corneal appearance so clear it looks as if it has not been treated. After resculpting, fluid is used to wash the inner cap and the corneal cap that was folded back is then repositioned.
Surgical markers placed along the flap edge allow very precise realignment if needed.
Corneal suction of fluid out of the cornea usually allows the cap to be secured quickly within minutes. Within two minutes normal blinking and related function occurs, though most surgeons allow five minutes. Strongly milking the flap edges may improve the initial adherence and have other advantages as well. However normal protective function, such as from a freak injury or strong rubbing of the eye, takes longer. Wearing sunglasses or other protective glasses for a few weeks guards against freak injury during this time.
