PURPOSE Decentration of the ablation zone is an occasional complication of excimer laser refractive surgery. We describe a technique to recenter the ablation zone without changing the refractive status obtained by the first surgery. METHODS Sixteen eyes of 14 patients had moderate or marked ablation decentration after previous excimer laser surgery for(More)

PURPOSE We describe a retreatment technique using a combination of large-diameter myopic and hyperopic excimer laser ablations of a near equivalent diopter value to enlarge previous small ablation zones without altering the refractive result obtained by the initial surgery. METHODS Eight eyes of six patients were retreated with a Technolas Keracor 217(More)
