This is a prospective randomized contralateral double-masked study. Each patient will be randomized as to which eye undergoes wave-front optimized (WFO) vs. wave-front guided (WFG) during Photorefractive keratectomy (PRK) or Laser-assisted in situ Keratomileusis (LASIK) surgery to determine which ablation profile provides the best visual outcome.
