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 myopia, but with only minor residual refractive error.
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 laser in order to enlarge the optical zone. All patients had a good refractive result after the initial surgery, but reported halos under low light conditions.
