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.
In 2015, the FDA approved a new laser ablation profile for performing laser corneal refractive surgery. Multiple sophisticated profiles have been developed in an attempt to optimize visual outcomes and reduce post-operative lower and higher-order optical aberrations. Among these include wave-front optimized (WFO) and wave-front guided (WFG) ablation profiles. The former compensated for corneal curvature to reduce spherical aberration and the latter, a more complicated ablation profile, was designed to minimize specific aberrations in an individual eye. Topographic profiles have also been used…
