White Cataract Surgery: USA Flag Sign (Femtosecond Laser)

The USA Flag Sign is seen when we use a femtosecond laser to assist in phaco of a white cataract.  You've heard of the Argentinian Flag Sign for white cataract phaco surgery, but what is the USA Flag Sign? The colors of the USA flag are red, white, and blue and we see these same colors when we use a femtosecond laser to create the capsulorhexis in a patient with a white cataract, we see the red (sub-conjunctival ring hemorrhage from the femto suction ring), white (the cataract), and blue (the Trypan dye used to stain the capsule). The femtosecond laser can be a useful tool for cataract surgery. In routine cataract cases, the benefit is typically mild and in expert hands, may not provide a meaningful improvement over manually performed steps of surgery. For this reason, in most of my cataract cases, I do not find myself using the femtosecond laser during cataract surgery. But in certain challenging cataract cases, the femto laser can be helpful in producing a better outcome and avoid certain complications.
