Dr. Whitman begins by making a 150- to 160-micron flap with a femtosecond laser. Next he measures the flap thickness using a 25-gauge cannula to keep the stromal side moist. He then lays the insertion device flat on the cornea, pushes down on the inlay, and pulls away the insertion device, keeping the stromal side of the flap wet. While the inlay is still moist, he checks that it is well-centered. Next he uses the cannula to apply BSS on the cut stromal side of the cornea, the edges, and the epithelial side. He then goes under the flap, flips it back into place, goes under the flap again, and lifts it to irrigate it and sweep it out for a much smoother, clearer flap. Finally, he sweeps it with a moist sponge, checks it with a slit lamp, uses an applanator to flatten it out, and sweeps it one last time.
