Flap smoother is a topical, noninvasive compression procedure, that helps in eliminating what is believed to be microscopic striae or fluid accumulation that lingers once the flap is replaced following laser in situ keratomileusis. It usually has a 5mm button, angled 30 degrees from the handle. The button is placed centrally, compressing the cornea, then a squeegee motion outward is used to gently massage irregularities out of the flap immediately after surgery. This flap smoother is also ideal for dealing with irregular astigmatism problems secondary to laser in situ keratomileusis. It provides the surgeon with another option other than lifting the flap and re-treating the patient, up to 6 months post-operatively.
