D = diopters; m = micrometres; = corneal dioptric power in the flattest meridian for the 3-mm central zone, = corneal dioptric power in the steepest meridian for the 3-mm central zone, = mean corneal power in the 3-mm central zone.
value—change from preoperatively to 1 year postoperatively (paired Student test).
